Project to use for reproduction.

1.) Run NetBeans
2.) Open attached project.
3.) Create new JFrame.
4.) Safely Delete JFrame from with Refactoring.
5.) Ensure focus is on Projects Widow by clicking on Project name.
6.) Click the Undo Button on toolbar and click Yes on dialog.
7.) Focus should still be on Projects window. Click the Redo Button on toolbar and click Yes on dialog.

This FileNotFound Exception is thrown.

8.) Cancel Exception Reporter.
9.) Focus should still be on Projects Window. Click Undo Button on toolbar and click Yes on dialog.

JFrame form comes back, but .form file is missing.

Comment 4 MackSix 2012-04-06 01:35:04 UTC 
If Undo/Redo is available in this case, it should reliably recover safely deleted files. This is dangerous and no workaround so I would say this is a P1.
Comment 5 Jan Becicka 2012-04-06 06:25:29 UTC 
Also reproducible in 7.1.
If you do Safe Delete / Undo / Redo you end up with deleted file. So I don't think, that this is P1.
Comment 6 Jan Becicka 2012-04-06 06:32:45 UTC 
FormRefactoringUpdate passes invalid fileObject to BackupFacility
Comment 7 Jan Stola 2012-04-06 14:51:04 UTC 
Fixed - trying to keep the corresponding dataObject/fileObject up-to-date during undo/redo of form removal.
