Description bondolo 2005-12-19 18:55:32 UTC 
Occurs while switching amongst file views with 200512182030 build. Every time I

occur through several different code paths:

Comment 1 Jan Becicka 2005-12-20 07:51:00 UTC 
Checking in Factory.java;
/cvs/java/parser/src/org/netbeans/lib/java/parser/Factory.java,v  <--  Factory.java
new revision: 1.10; previous revision: 1.9
done

I improved exception logging - it should help us to find root cause of this bug.
Comment 2 bondolo 2005-12-20 17:42:05 UTC 
This seems to be related to generation of the navigator pane and/or code
completion. Both are completely broken for me right now.
Comment 3 Jan Becicka 2006-10-26 16:27:28 UTC 
Javacore module was replaced by Retouche infrastructure. This bug is not valid
in trunk any more.
Comment 4 Quality Engineering 2007-09-20 10:46:18 UTC
