Description Jesse Glick 2004-05-13 22:22:51 UTC 
I tried to open
java/project/src/org/netbeans/modules/java/project/JavaTargetChooserPanelGUI.java
in a current dev build. Got an NPE, didn't see the
file opened, everything I tried gave me more NPEs,
had to shut down the IDE to get rid of it.

Comment 2 Jesse Glick 2004-05-13 22:25:41 UTC 
Happened even after deleting Windows2Local and restarting. Cannot open
form -> P1.
Comment 3 Milos Kleint 2004-05-14 07:32:00 UTC 
fixed in core/multiview by setting an empty name to prevent NPE.
however cannot assign correct name before opening/reading the initial
element in multiview.

Problem with the mentioned form seems to be fixed. But I got a similar
NPE again in a dev build I just made from trunk sources, after trying
to restart. No forms open, just a plain Java source and a text file,
maximized. IDE did not start; had to blow away my Windows2Local.

Reproducible - just open My Favourites window (Ctrl-3) with that
module installed, then restart.
