Description wobster 2010-04-17 17:25:08 UTC 
I created a Desktop Application and then attempted to add a new action to a button using the GUI editor. When I hit OK, the annotated method (@Action) does not appear in the code nor in the *view.properties file. I noticed that I am getting the following exception in the NetBeans log file. I have updated NetBeans 6.8 fully and added a number of other plug-ins (like findbugs) so its possible that one of those may have broken the Desktop capability.

Comment 1 wobster 2010-04-17 20:12:50 UTC 
There is a chance that this bug was caused by either PMD or the CheckStyle plugins. I disabled those two in NetBeans and the problem seems to have gone away. (FindBugs is still enabled though.) I'll let you know if I find out more details.
Comment 2 Marian Mirilovic 2010-04-19 05:47:00 UTC 
not a P1 ... I am not able to reproduce it in NB 6.9 (clear install without additional plugins)
Comment 3 Jan Stola 2010-04-19 11:11:39 UTC 
I am sorry, I am not able to reproduce this issue and the attached exception is not sufficient to track the problem down => closing as non-reproducible. Feel free to reopen this issue if you are able to provide exact steps to reproduce. Thank you in advance.
Comment 4 wobster 2010-04-22 13:08:00 UTC 
I am fairly certain the problem was caused by an interaction of either the PMD or CheckStyle modules and the editor. I left FindBugs enabled and I was able to use the Java Desktop project and editor without any issues. When I get a chance, I'll report an issue to the https://sqe.dev.java.net/ project.
