[MSementsov-Ibk]

When selecting multiple nodes and creating an invalid geometry and then pressing enter, multiple error dialogs show up.

Issue confirmed. My only concern is whether it is appropriate to add to EnableAcceptEditCommandHandlerActivator class a dependancy on org.eclipse.ui.* classes.

This is still a problem.
I agree the proposed fix is not as elegant as we might like.
Perhaps we need to get at the root cause of why the acceptCommands are executed 8 - eight - times.
It looks like org.eclipse.e4.ui.bindings.keys.KeyBindingDispatcher.executeCommand(,) is not flagging the event as handled and the event gets fired by every control in the hierarchy as a "traverse" event.
