The Flyway migration previously ran BAM migration scripts and Flyway attempted to execute the scripts before LSPS migration scripts. As a result, the migration failed. The scripts have been excluded from the dependencies. (LSPS-10056)

3.3.2061

Installer

Fixed Issues
  • Migration scripts for BAM Library have been added to the LSPS maven repository so the user no longer needs to acquire the LSPS Runtime package to perform database migration. (LSPS-10052)

3.3.2060

Additional Libraries

Fixed Issues
  • The scaffolding_forms::EntityDetail and scaffolding_forms::EntityOverview components, could not define the value of the Caption property: Any attempt to define the value resulted in a validation error.

  • If a parameter passed to navigation to a document (navigateToDocument(DocumentType documentType*, Map<String, Object> parameters) or to its Java version getNavigationUrl(RecordHolder navigation) ) had value null, it was incorrectly converted to a parameter with value "null". Now the parameter value is ignored as expected. (LSPS-9992)

UI

Fixed Issues
  • In the Vaadin-8 implementation, even if the options of a ComboBox did not contain an option with no label, an empty option was available. (LSPS-9989)

  • The UITester class can now specify the timeout parameters for page load, script timeout, and implicit wait for the clicker tests. (LSPS-9954)
  • When a Dashboard was hidden and re-displayed, for example, when switching between Tabs, the size of the Dashboard was not set correctly. (LSPS-9956)
  • The Single-Select List was rendered incorrectly when its data contained only one item. (LSPS-9960)
  • In the form definition, you can now add CSS rules to a form directly from a form component with the addStyleSheet(String sheet) and remove such rules with the removeStyleSheet(String id) method. The methods allow style-sheet changes in cases when the user works exclusively with a model without the LSPS Application. The style rules as applied and removed as the given component is attached and removed respectively: it is therefore recommended to define the rules on the uppermost form component. The feature is intended for prototyping and testing of style rules. Once you are happy with the styles, add them to your LSPS Application.
    c.addStyleName("unread-comment")
    def String cssId := c.addStyleSheet(".unread-comment { background-color:aliceblue }");
    c.removeStyleSheet(cssId)
    (LSPS-9968)
  • The LspsTabSheet test class could not open a tab if it was not visible due to too many tabs. (LSPS-9969)

Fixed Issues
  • When you drop multiple files to a single Drop Zone component, the files are handled at once by a single callback. Note that the change is backwards incompatible since the upload result listener has now a list of files and a list of error messages as its input. (LSPS-9009)
  • The multiple options filter of a grid with a custom datasource returned its current value as an Object of a non-record type making it difficult to work with it in the Expression Language. This has been corrected so it now returns a list of Filter records. (LSPS-9889)

Management Console

Improvements
  • The user data on the Settings page now contains all relevant data and features, such as, substitution, and security roles data. (LSPS-9802)
Fixed Issues
  • If the user did not have the Log:Read security right, accessing logs of model instances in the Management Console caused an error. Now the message on insufficient access right appears. (LSPS-9878)

3.3.2051

Forms

Improvements
  • The value-change event (ui::ValueChangeEvent) now has the oldValue property with the value that was stored in the binding prior to the given value change event. Therefore, if the user is changing the value, it returns the last valid value. If the binding value was set programmatically, it returns the value from binding even if the value is incorrect. (LSPS-9863)
Fixed Issues

3.3.2044

Forms

Improvements
  • You can now listen for sorting and filtering on Grid with the setSortListener() and setFilterChangedListener() methods. (LSPS-9793)
  • The clearBinding() convenience method for <componentWIthBinding>.setBinding(null as ObjectBinding) has been added. (LSPS-9798)
Fixed Issues
  • Error messages on components can be added as validators (addValidator()), custom messages (setCustomErrorMessage()), the infer validation feature (inferValidator()), or showing constraint violations (showConstraintViolations() and showDataErrorMessages). Previously, only one set of the error messages was displayed resulting in missing error messages. (LSPS-9691)
  • The error popups in the Application User Interface now contain the full call-stack with precise information about the error cause. (LSPS-9786)
  • Previously, the server returned an exception when the user attempted to edit an enumeration in an editable grid. This update adds the editor for enumerations and the enumerations in the scenario become editable as expected. (LSPS-9789)
  • When filtering a grid, the selection retained items that were no longer visible. (LSPS-9791)
  • When a Grid Column had the value provider set to Property path and the record had value null, the server returned an NPE. With this update, a non-editable row is rendered. (LSPS-9794)

UI

Fixed Issues

3.3.2042

Forms

Improvements
  • You can now define the value providers for sorting and filtering for grid columns and that either in their Properties on the Sorting and Filtering tab or as parameters of the addColumn() method. (LSPS-8953)
  • The PDFViewer component is now by default rendered with a non-zero width and height. (LSPS-9683)
Fixed Issues
  • The setFiltrable(false) method did not work correctly and resulted in, the filter was displayed on all columns, even if you set it to disabled on a column. (LSPS-9582)
  • Methods for sorting Grid Columns setSorted(), isSorted() and isSortAscending() have been added. (LSPS-9770)
  • Drag-and-dropping of Grid Columns is now supported: the feature is enabled and disabled by the setColumnReorderingAllowed() method. To allow the user to check if the feature is active, the isColumnReorderingAllowed() methods have been added. The getColumns() method has been adjusted to return column in the current order with the possible changes introduced by dragging-and-droppping of columns and to include any hidden columns; (LSPS-9771)
  • You can now select all items in a grid in multiselect (MULTI) selection mode with the Select All check box. Note that by default the check box is not available. The availability of the check box is set with the setSelectAllCheckBoxVisible(Boolean) method. When you use the select-all feature, all items in the datasource are loaded into memory therefore make sure not to use the feature on large data sources. (LSPS-9776)

Management Console

Improvements
  • When the user did not have the security right to change their own password, their password fields were still editable on their detail when accessed from the Persons page. After an attempt to change the password, the operation failed with an error. This also prevented the user from changing other details and setting on this page. Now the password fields are read-only under these circumstances. (LSPS-9754)
Fixed Issues
  • Previously, when editing the security rights of a person, all the rights were unset and therefore removed from the person on save. This was caused by Vaadin update and has been fixed. (LSPS-9766)

SDK

Improvements
  • In addition to generating a Java class for a record, you can now define for each Record whether to generate Java interfaces with the required properties and, the property getters and setters. (LSPS-9773)
  • When generating Java classes for your data types, you can now map an existing Java class to your Enumeration types: the setting is available on the Java tab of Enumeration properties and prevents the enumeration classes from being generated. (LSPS-9774)
  • When generating classes for records, you can now specify the target project and package for the generated Java sources for each module. (LSPS-9775)

  • When the user tried to sort a table column that contained a record, the action resulted in a NullPointerException, which occurred as a result of a ClassCastException. Now, the column content is sorted according to record ids. (LSPS-9767)
  • API for UI Vaadin 7 and UI Vaadin 8 component factories is now exposed via the createV7Factory(connector) and createV8Factory(connector) methods to allow easier factory customization. (LSPS-9777)

3.3.2041

Command-Line Console

Improvements
  • The db-migration tool used an outdated SQL Server driver. Since the driver was no longer maintained, hibernate errors could have occurred. The Microsoft JDBC driver for SQL Server driver is now used.

    (LSPS-9732)

Forms

Fixed Issues
  • If a table column contained a multi-select options filter, the filter fired events that caused redundant loads of the table data source. (LSPS-9737)

PDS

Improvements
  • You can now easily define count queries for HQL queries directly in the query definition. Note that count queries of HQL queries with group by do not work correctly. (LSPS-9727)
Fixed Issues
  • You can now use parameters of HQL query in the start index and count parameters of the query. (LSPS-9726)

Server

Fixed Issues
  • Local variables of Inline Event Subprocesses failed to be initialized correctly. (LSPS-9729)

UI

Fixed Issues
  • The Vaadin 8 implementation of the UITextBox has been added: note that switching to this implementation introduces backwards incompatible changes and hence requires thorough testing. (LSPS-9734)
  • The UI Vaadin 8 implementation of the check-box component has been added. (LSPS-9736)
  • The LSPS Application has been adjusted to allow switching between Vaadin 7 and Vaadin 8 implementations of UI forms. This requires you to adapt existing LSPS Applications so that they use one of the new component factories: in the DefaultLspsAppConnector class or your custom class that extends it, adjust the getComponentFactory() method so it returns the required UI factory implementation:
    • UIComponentFactoryV7Impl to retain the current implementation, originally called UIComponentFactoryImpl.
    • UIComponentFactoryV8Impl to use Vaadin 8 implementation.

      With this factory, component implementations in Vaadin 8 will be used if available (The implementations will be provided gradually). Note that new implementations will not be backwards compatible and your forms will require thorough and full testing.

          @ Override
          public UIComponentFactory getComponentFactory() {
                      //original content:
              //return new UIComponentFactoryImpl(this);
              return new UIComponentFactoryV7Impl(this);
          }

  • The db-migration and lsps-cli tools available in the LSPS runtime package have been reworked to provide a more consistent experience: they are now provided as jar files and delivered in the cli-tools directory of the runtime package. (LSPS-9596)

Forms

Improvements
  • The table failed to detach some of the components that were no longer needed. Later these were detached automatically and the event was logged as a warning. This has been fixed and the logs are no longer cluttered. (LSPS-9483)
  • The modeling ID defined on a Reusable Form component in the calling form is now preserved on runtime. Also the findByFormId method that returns the components created by the reused form has been added to the test bench. (LSPS-9682)
  • To provide better support for the sorting feature of tables, the following methods have been added to table columns:
    • setSorted: sorts the column in the ascending or descending order and deactivates sorting
    • isSorted: returns whether the table is sorted by the specified column
    • isSortAscending: returns true if the sorted column is sorted in ascending order (LSPS-9688)
Fixed Issues
  • In the testing suite, the getId() on components with no ID defined now returns null and no longer fails with an exception. (LSPS-9697)
  • Previously, in Pdf Viewer, pressing Enter did not produce a change event in Internet Explorer: as a result, when the user entered a page number into the page-number field and pressed Enter, the document failed to navigate to the page. (LSPS-9713)

PDS

Fixed Issues
  • When defining constraints in the text editor, validation now checks if the used constraint property, tags, and constraint types exist. (LSPS-9718)

UI

Web Application

Improvements
  • When attempting to perform an action over finished model instances, the server threw an exception, which was logged with its stacktrace into logs leaving them cluttered with generally irrelevant data. Now, the server logs a brief warning into the logs and the details are added to error logs. (LSPS-9711)

3.3.2038

Improvements
  • A new security right, Log:Read, that governs access to Logs created by the Log task and log() function has been added. (LSPS-9657)

Web Application

Fixed Issues
  • Maven used by PDS has been upgraded to a newer version, which tracks the source server of artifacts instead of only checking their name and groud id. As a result, when generating the LSPS Application, some artifacts fetched from other repositories were ignored and the generation failed. After this upgrade, the maven build of the LSPS Application is run with -Dmaven.legacyLocalRepo=true which restores the original behavior. (LSPS-9609)

3.3.2037

Forms

Improvements
  • The setOnValidValue() method has been added to input components. The method runs after the value has changed and the isValid() call has returned true. (LSPS-9629)
  • Input components now have the getUserText() method, which returns the content of the input field even if the input does not meet the requirements of validators. Also, the setNumberFormats(List<String>) method has been added to the DecimalField so that you can now define multiple input format. (LSPS-9635)
Fixed Issues
  • It is now possible to clear binding of a component by passing the null parameter to the setBinding() method, for example, myTextField.setBinding(null as Reference). (LSPS-9584)
  • In testbench, the selectBySubstring() method has been added to the combo-box components so you can select an option that contains a substring. (LSPS-9586)
  • Under certain circumstances, an expandable Text Area could have lost the scroll bar. (LSPS-9616)
  • The robustness of data serialization has been improved to prevent potential security exploits. (LSPS-9640)
  • The property DataSeriesItem.itemColor that defines the color of the given data item has been added. Also, the DataSerieItem.color property, which has never been applied on the data item, is now deprecated. (LSPS-9671)

PDS

Improvements
  • You can use an expression to define the BLOB size in data type models, such as, 1024*1024 //evaluates to 1048576. The BLOB expression must return an Integer and cannot access any constructs or variables from higher contexts. (LSPS-9541)
  • Textual definitions of constraints now support auto-completion. (LSPS-9560)
  • The Filtered roles field of the Modeled Roles dialog for a person no longer overflows to the drop-down with its values. (LSPS-9619)

  • You can set the error message displayed on a Date Field or Local Date Field when the entered date is not in an allowed format with the setParseErrorMessage(String message) method. (LSPS-9624)
  • When opening a PDF in your browser, the browser saves data about the currently open page, applied zoom, and sidebar position. Previously, the PDF Viewer component always applied this data when it was available. Now you can enable or disable this behavior with the setRestorePdfStateOnLoad() method. (LSPS-9626)
  • The isConvertible() method of components that hold a value has been deprecated. Equivalent functionality is provided by the isValid() and getErrorMessages()methods. (LSPS-9634)

PDS

Improvements
  • In property paths, the use of dot access (.) operator is now validated as a warning when preceded by the safe-dot (?.) operator since the safe-dot access is rendered ineffective. For example, person?.address.street is considered invalid since the street access could return a NullParameterError. (LSPS-9632)

Server

Improvements
  • LSPS now logs messages about database schema update when a model with a modified schema is uploaded. (LSPS-9638)
Fixed Issues
  • When uploading a model with an updated data model and the upload strategy set to Updated database schema and a conflict between the schemas arose, the upload failed with the SqlExceptionHelper error violated - child record found. This occurred due to incorrect order when deleting the model data. (LSPS-9617)
  • If a to-do with a binary was persisted multiple times, the binary ID could have been used by another object: This could have resulted in a ClassCastException or use of an incorrect object or incorrect data. (LSPS-9630)

3.3.2034

Forms

Fixed Issues
  • When the user entered text into a text area, the page stopped responding due to an infinite loop in the text area. This happened, due to a conflict in an HTML attribute and CSS style rules of the text area. (LSPS-9615)

If you keep experiencing issues when building the LSPS Application after PDS upgrade, please, delete the maven repository, <home>/.m2/repository by default. (LSPS-9594)

Server

Fixed Issues
  • When a parent record has the O-R mapping set to "Each record to own table", the tables of its child records hold only values for not-inherited fields: parent's fields are stored in the parent table. When the child inherited the ID from the parent, previously, the database did not contain a constraint that would restricts the foreign-key value in the child to be identical with the primary key of the parent. (LSPS-9610)

3.3.2032

Command-Line Console

Improvements
  • The flyway:clean, flyway:repair, flyway:migrate options have been added to the migration tool for LSPS database initialization and migration tool to allow to define the flyway run (the migration is run by the migration.sh and migration.bat script). (LSPS-9605)

3.3.2031

Forms

Fixed Issues
  • When a model used a version of the standard library that did not have the forms::setModelingId() method, the model compilation, which is performed either right after model upload or when a model is first requested, failed with a ModelUploadException. This caused backwards incompatibility of models. Models with such standard libraries are now compiled without calling the setModelingId() method and the models are compiled successfully. (LSPS-9601)

Navigation Engine

Improvements
  • The errors in server log now include information about which gateway was involved when applicable. (LSPS-9597)

3.3.2030

Forms

New Features
  • The forms::Slider component has been added. (LSPS-8854)
Improvements

  • Previously, if you wanted to insert an icon from the vaadin font into your form, you had to insert a piece of html code with the required classes set into a Label component. You can now use the vaadinIicon() function to do so. Also, to get a list of the available icons, you can use the allVaadinIconNames() function. (LSPS-9227)

Installer

Fixed Issues
  • If the user did not select the Create desktop shortcut option, the process resulted in a corrupt installation. (LSPS-8934)

PDS

Improvements
  • The select components Combo Box, Single Select List, Multi Select List, Check Box List and Radio Button List can now define their options as a collection: the label for the options is calculated as the value returned by the toString() call on the collection item. (LSPS-6170)
  • The underlying Eclipse has been upgraded to Eclipse Oxygen. (LSPS-9163)
  • You can now enter the @Disabled annotation into a method definition file before the record name to exclude all the methods from validation. (LSPS-9182)

Fixed Issues
  • Previously, the PDS Embedded Server returned the following bogus error, when initializing its H2 database:
    Exception to find schema version.: org.h2.jdbc.JdbcSQLException: Table "LSPS_SCHEMA_VERSION" not found;
    This occurs due to a missing table with the data on the database schema, which is not required by the PDS Embedded Server. With this update, the PDS Embedded Server returns a warning. (LSPS-8946)
  • The GO-BPMN Search allows you to define whether to search for functions, methods, or constructors. (LSPS-9222)
  • If an HQL query used the keyword distinct in its select, the query failed with a com.whitestein.lsps.lang.exception.ValidationException error. (LSPS-9271)
  • In an HQL query, select can now use property path as well as an alias. (LSPS-9272)
  • In an HQL query, a property of a record was resolved incorrectly when used in the with clause and the query failed with an org.hibernate.hql.internal.ast.ErrorCounter error. (LSPS-9274)
  • Under certain circumstances, saving a modified data-type definition file after undoing changes could have failed with an exception. (LSPS-9287)
  • In the Expression Evaluator, pressing CTRL+Enter inserted a new line character \n into the evaluated expression. The key combination now send the expression for evaluation as is as expected. (LSPS-9302)

Platform

Fixed Issues
  • Previously, it was necessary to replace the javassist of the WildFly and JBoss server with a custom LSPS javassist and modify the jboss-deployment-structure.xml accordingly. With this update, these changes are incorporated in the jboss-deployment-structure.xml, which renders these steps unnecessary. (LSPS-9097)

Server

Improvements
  • The server now logs information on incorrect LSPS database schema version. (LSPS-8187)
  • The change proxy mechanism has been reworked to provide a more flexible and safer way of working with shared records.

    • It is now recommended not to merge your proxies directly but adding them to a RecordProxySet object and merge the set.
    • You can now define whether the server should perform an optimistic-locking check on the records on merge.
    • The merge functions mergeProxiesDeep(RecordInstance1, ..) and mergeAllProxiesDeep(List<RecordInstances>) have been removed. The same functionality can be achieved with the merge call of a RecordProxySet. (LSPS-9215)
  • The HealthCheck MXBean with attributes related to monitoring of the LSPS Application has been added and is accessible from JMX monitoring tools such as JConsole. The MXBean can be used for integration with Nagios. (LSPS-9242)

  • Native queries previously failed to map Boolean database type to a record property when running on a MySQL database. (LSPS-9221)
  • The BinaryHolder type is now serializable. (LSPS-9288)

Standard Library

Improvements
  • The notifyModelInstance() function that allows you to invoke a model instance has been added to the Standard Library. (LSPS-9095)
  • The function and extension method getProperty() has been added: it takes a Record and a String name parameters and returns the property of the Record with the name or null if such a property does not exist. (LSPS-9211)
  • The function sortByKey() has been added: it takes a collection of objects to be sorted, the keyExtractor closure that retrieves the keys to use for sorting and returns a list of elements sorted by the keys produced by the given keyExtractor. (LSPS-9214)
  • The groupBy() function, which aggregates a collection of items into groups with particular classifiers, has been added. (LSPS-9224)
  • The getRecordSupertype() function has been added: it takes a record type and returns its supertype.

    (LSPS-9241)

  • The function toInteger(String string, Integer radix) that allows the user to parse numbers with different bases has been added. (LSPS-9255)
  • The function isReadOnly(PropertyPath) and its extension method have been added. (LSPS-9265)
  • The functions for checking properties isPrimaryKey(Property property), isAutogenerated(Property property), isVersion(Property property) have been added. (LSPS-9266)
Fixed Issues
  • Previously, a record could have had two fields with the same name where one was inherited from its supertype and the other field was defined on the record. Such a situation now renders the model invalid. (LSPS-9180)

UI

Improvements
  • The Navigation Link component is now considered an action component. (LSPS-9304)
Fixed Issues
  • The Link component failed to navigate to the target location due to incorrect logic in history storing. (LSPS-9301)

Web Application

Improvements
  • When you generated the LSPS Application, PDS previously created the maven build configuration and application launch configuration as local files in the current workspace. These launcher configurations are now created in the <YOUR_APP>-embedded project so they can be easily shared and version-controlled as part of the application. (LSPS-9223)
Fixed Issues
  • The technical user processAgent can no longer log in to the Process Application via the login page. (LSPS-9200)

3.3.2002

Expression Language

Fixed Issues
  • If the iterator of the foreach loop was changed via its reference from the loop, write access was successful. Such write access now causes an error on runtime. (LSPS-9159)

Forms

Fixed Issues
  • A NullPointerException that occurred when saving documents with ui forms has been fixed. (LSPS-9154)

PDS

Improvements
  • You can now create queries in HQL. (LSPS-9000)
  • The Module Management view of the Management perspective now displays the module hash code and the number of unfinished model instances if applicable. (LSPS-9030)
  • If you declare a function with no parameters as an extension method, the validation now detects the missing required parameter as an error. (LSPS-9131)
  • TODO markers in task parameters are now detected and displayed in the Task view. (LSPS-9142)
Fixed Issues
  • When the user defined a UI listener in the Listener dialog and then selected Listener is defined by expression, the generated expression did not contain the executionContext field and the listener was executed in the top level context. (LSPS-9136)

Standard Library

Fixed Issues
  • An exception could occur when the user attempted to open or submit a saved to-do. This happened due to inconsistencies in the context of objects returned by the makeCopy() method of model instances and the synchronize(ModelInstance original, ModelInstance toBeSynchronized) of EvaluationLevelUtils. The calls now return objects with correct context. (LSPS-9174)

UI

Fixed Issues
  • When the user defined a UI listener in the Listener dialog and then selected Listener is defined by expression, the generated expression did not contain the executionContext field and the listener was executed in the top level context. (LSPS-9136)

3.3.2001

Expression Language

Improvements
  • Closures which reference only their arguments and global variables are executed more efficiently. (LSPS-8878)
  • The memory footprint of contexts related to closure and function invocations has been significantly diminished. (LSPS-9082)

PDS

Improvements
  • The Expression Evaluator REPL View has been added so you can test expressions on design time. (LSPS-8920)
Fixed Issues
  • When you changed the name of an element in the Properties view and a diagram with the element was displayed, the name in the diagram was not refreshed immediately. (LSPS-9069)

Standard Library

Improvements
  • The getAllSubGoals(Goal goal) and getSubGoals(Goal goal) functions and their extension methods that return the immediate and all sub-goals of a goal have been added. (LSPS-9103)

3.3.2000

Forms

New Features
  • The LSPS Application now uses Vaadin 8. This has the following impacts:
    • Internet Explorer 8, 9, and 10 are no longer supported.
    • Java 8 is required.
    • Connecting classes of custom form components that use Vaadin implementation might need adjusting if their Vaadin API changed. (LSPS-9340)

Other

Fixed Issues
  • After installing LSPS Cloud Edition, PDS failed to connect to the server due to a certificate unsupported by older Java versions. Now the installer as well as PDS will warn the user that a newer Java version is required. The Java bundled with the installer has been upgraded so the certificate is now accepted by this Java as well. (LSPS-8849)

PDS

New Features
  • Support for decision tables has been added: you can now design decision tables with your business rules in PDS, display and edit them in the Application User Interface, and use them to obtain decision results based on the rules. (LSPS-8834)

SDK

Improvements
  • If an implementation Java class of a task was not available on the server, the system failed to detect the problem. The system now logs the full stack trace in such cases so it is easier to identify the problem.

    In addition, you can now upload models created in LSPS 3.0 and older and check whether a task implementations is missing. This was previously not possible because the HumanInteractionTask was removed in LSPS 3.1. On execution, the task throws an exception. (LSPS-8929)

UI

New Features
  • The LSPS Application now uses Vaadin 8. This has the following impacts:
    • Internet Explorer 8, 9, and 10 are no longer supported.
    • Java 8 is required.
