I've an rcp application with the classic Edit/Undo and Edit/Redo commands.
Their activeWhen clauses look like this (undo case):
where undo.history.canUndo is a propertyTester that returns:
The problem is that it seems that the activeWhen clause is only
evaluated when the selection changes, and not each time the Edit menu is
If I undo an operation without changing the selection, the handler
active-state isn't refreshed and the UI goes out of sync with respect to
the canUndo/canRedo status.
How can I solve this?
How do you guys handle your Undo/Redo commands?
