Comment 1 Peter Lam 2007-03-20 23:13:47 UTC 
low use case not currently impacting our installed user base.
Comment 2 Yang Su 2007-07-20 22:47:51 UTC 
put temp fix to address exception, the design pattern tree view will be re-written later.
Comment 3 Sherry Zhou 2007-09-14 22:49:11 UTC 
Can not verify this bug until 78873 is fixed
Comment 4 Peter Lam 2007-10-26 00:06:44 UTC 
verified in the latest trunk build 20071025193521.
This issue is independent of issue 78873. The problem in this issue is that once F2 is pressed, NPE occurred. This is
now fixed and NPE no longer occurred but F2 action will not enable the editor mode for rename. So mark it as verified.
