Start IDE with a clean userdir 3. Invoke File | Open Project... action 4. Select unzipped project default 5. Scanning structure of project should be performed (it takes a while) 6.

Fill a new field name protectedPropertyRenamed, check checkbox 'Rename Getters and Setters' and confirm this dialog. There should be displayed a warning: O There are methods in subclasses/implementors of BeanA that override or implement this method. They will also be renamed. 8. If you agree with these changes press Do Refactoring button and changes will be performed. 9. Pressed Undo action. 10. This error shows up. Created attachment 117425 [details]

Undo a moved JFrame form with Internationlization.
I've reproduced the problem in a project attached by ttokoly according to given steps. I've fixed the NPE but undo of the refactoring does not succeed although I did no extra modifications (see attached analysis) so reassigning to refactoring for further evaluation. openide.text partial fix: http://hg.netbeans.org/jet-main/rev/248f9b21ad44 Created attachment 118141 [details]
