Description Jan Stola 2011-10-10 19:03:59 UTC 
Steps to reproduce:
1. Open grid-designer (=customizer for GridBagLayout).
2. Select some component.
3. Press some of the 'plus insets' buttons 60 times.
4. Press undo many times (~50 times) until it starts to beep.
   => Undo action is enabled, but it doesn't undo the last action,
   it just beeps.

The described test-case is artificial, but it is a good way to reproduce the problem that can occur after more complex steps during real usage.

Undo action does nothing in the described test-case because the undo-queue of the corresponding UndoManager is empty. Every UndoManager has a limit on number of edits that can be undone and we exceeded this limit. Hence, the root of the problem is that the Undo action is enabled in such case.
Comment 2 Jan Stola 2011-10-10 19:44:56 UTC 
Fixed - Undo action should be disabled correctly by now.
