To track incomplete expressions and modeling elements, use the //TODO marker. You can parametrize the marker in the form /*TODO <TEXT>*/. The <TEXT> is kept as the marker's description.

You can view all such Markers in the Eclipse Tasks view. To open the view, go to Windows > Show View > Tasks.

The TODO Marker

Alternatively, to track incomplete modeling elements, you can apply a modeling status with a priority to the element: The priority is interpreted as a task marker.

Modeling status with the normal priority on an element with its entry in the Tasks view

If elements in a modeling status with a priority are not displayed, check the filtering of the view: in the Task view, click the View Menu (

) button and select Configure Contents. Make sure the filtering is set correctly and set the required priority.
