Hi,

I have installed the key handler for the DEL Command of an EditPArt in GEF...
.....the delete of objects has be worked fine - but after some code changes the
MyDeleteCommand.execute() will not be called!!

If I select an EditPart (Figure) in the GEF the "call history" of my programm
looks like:

(the root edit part) 1. > FormElementEditPart.getDragTracker

(my edit policy) 2. > ComponentEditPolicyForwardDelete.getDeleteCommand
3. > GroupComponentEditPolicy.createDeleteCommand
4. > ComponentEditPolicyForwardDelete.getParentDeleteCommand
5. > XYLayoutEditPolicyFormImpl.getDeleteDependantCommand
(delete of the slec. object)6. > DeleteGroupCommand.DeleteGroupCommand
7. > XYLayoutEditPolicyGroupImpl.getDeleteDependantCommand

8. > DeleteGroupCommand.DeleteGroupCommand

I can see, that the right delete command has been created.
But the execute method will not be called if i press the DEL
key.

Greetings

Andreas

If you have a global DeleteAction registered, you don't need the KeyHandler
to do this.

Regarding this problem, does the CompoundCommand's canExecute() method
return true?
