1. Duplicated a form file without refactoring (Copy&paste);
2. Try to rename the file
Comment 3 Jan Stola 2012-04-17 09:43:46 UTC 
The described steps work fine on my machine. Are you still able to reproduce the attached exception when you follow these steps or it happened just once/twice?

The stack-trace shows that GUI Builder was not able to find initComponents section during refactoring. Unfortunately, it is not clear why that happened.
Comment 4 Michel Graciano 2012-04-27 13:58:50 UTC 
No, it is not reproducible anymore. Sorry for the delay.
