stacktrace

no netbeans specific code in the stack trace. can QA pls try reproducing or contacting reporter(s) for more info? thanks

I went through a few xml logs in exception reporter. It seems that the exception happens after action in editor eg. CC
or tab. Reassigning to editor for evaluation. Maybe some better logging in uigestures could help to find out what happens?

Well, I'm sorry, but I'm going to say the same as saubrecht. There is no Netbeans specific code on the stacktraces and
without steps to reproduce there is really nothing we can do.

there are 15 duplicates of this issue in exception reporter so i'm not sure it really deserves its P5 :)

alexanderfrey, drucik, do you remember when the issue happened? Are you able to reproduce it? Any steps?

thank you


@P5 - when there will be more than 20 duplicates then it will become P2 automatically ;) But we don't know how to
reproduce now.

stacktrace

IMHO we are hitting http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6253801 in some form i.e. we are adding into a
jlist in non-AWT thread causing the exception below to occur in AWT.
I'll try to patch JDK with an aspect to find a culprit.

So far I've only found the problem attached - ActiveConfigAction calls JComboBox.setModel() outside AWT. Reassigning to
projects for evaluation.

JComboBox.setModel() called outside AWT

Fixed. Setters on realized component are called on EQ.

Log: #146448: calling setters on realized component on EQ

I am getting this issue on a October dev build 200810100201. This issue was supposedly fixed in September.
What I was doing is opening a java file containing a couple of method declaration with no java extension. I dont expect
NB to recognize it as a java file, but I doubt I should be getting this error every time.

*** Issue 152467 has been marked as a duplicate of this issue. ***

is it still reproducible?

 nsegura3 , could you attach the file that you are able to reproduce it with?

Reopening - reproduced in NetBeans IDE Dev (Build 200812180001)
http://statistics.netbeans.org/exceptions/detail.do?id=2458

Setting model outside AWT was fixed in ActiveConfigAction (projectui). Other comments from exc. reporter show that the
problem (list manipulation outside of AWT) is also in other parts of IDE, reassigning to generic component.

closing as fixed since the problem was fixed in projectui. Other cases will be reported as separate problem by 
exception reporter if it appears again.
