Show errors during execution of EMF commands to user
Modifications of the model are managed by the ICommandStackService
. As of now, in case the code inside commands fails and raises an exception, the problem is only logged to the console, but not shown to the user.
This is problematic, since a major reason for such failures are input models that do not satisfy the assumptions of the command.
Suggested change: show message explaining the problem in a dialog box.
