Description zikmund 2004-07-28 17:08:03 UTC

Build 200407271830

This happened to me once:
1) I started with clean userdir
2) closed the Welcome screen
3) clicked New Project tool bar icon
4) ERROR:
NPE appeared -- see attachment
Notice: after exception dialog closing, the
description of project was empty.

BTW: I noticed twice that the description of
project contains licence HTML text a week ago. It
could be related to this - probably some race
condition.

NPE

Comment 2 Jesse Glick 2004-08-04 03:05:18 UTC

What JDK? Probably a JDK bug.

Comment 3 zikmund 2004-08-04 14:32:13 UTC

Tested on JDK 1.5.0 beta3-b59 (WinXP SP1).

Comment 4 Jesse Glick 2004-08-10 05:00:15 UTC

Probably shouldn't be calling methods on JEditorPane off the event thread?

Comment 5 zikmund 2004-08-13 10:38:26 UTC

It happens me once in 10-20 IDE runs. Raising priority to P2.

I've got different exceptions (different NPE and ClassCastException)
in last 2 occurences -- see attachments (I have also IDE logs if it
could help you)

Comment 8 Jesse Glick 2004-08-13 19:38:47 UTC

The last two exceptions may or may not be at all related to the
original one.

Comment 10 Petr Hrebejk 2004-08-17 17:00:51 UTC

This might probably be marked as fixt after all the setters in
TemplatesPanel will really run in the AWT thread.

Comment 12 Tomas Zezula 2004-08-19 13:38:53 UTC

I fixed a lots of bug in the ProjectsTemplateChooser related to
calling swing from non AWT thread, could you be so kind and verify
this issue with sources newer than 19/8/2004 14:40

Comment 13 Tomas Zezula 2004-08-19 13:54:10 UTC

I am not able to reproduce it anymore. If it happens again please
reopen it.

Comment 14 Tomas Zezula 2004-08-19 13:54:50 UTC

Fixed the AWT threading.

Comment 15 zikmund 2004-08-26 13:16:07 UTC

Marking as verified -- I can't reproduce it after the fix.
