Description Roman Strobl 2005-02-22 13:14:29 UTC 
[NetBeans 200502211900; JDS R3; JDK 1.5.0_02]

When setting main class for attached project I am
sometimes not able to click on the OK button
because it is disabled. Sometimes the button is
disabled and sometimes not. I wasn't able to
reproduce it on another project, although there's
nothing special on the attached project IMO.

Roman, you didn't try to set the main class with "background scanning"
turned on, did you?
Comment 3 Roman Strobl 2005-02-23 09:25:03 UTC 
The bug is independent on the background scanning property setting.
Today it was harder for me to reproduce it (seems as some random race
condition to me...). Today it failed in 1 case of cca. 50 while
yesterday it failed in 1 case of cca. 5. I attach screenshot of the
dialog. A workaround is to close the dialog and try again, the
probability that OK button won't be disabled next time is high.

Comment 5 Tomas Zezula 2005-02-24 12:39:05 UTC 
This is a threading issue, the listeners are registerd int the AWT
Thread after the async job searching all main classes is started and
the async job (non AWT Thread) calls back into AWT.
