Description Kenji Tachibana 2007-12-10 07:46:19 UTC 
When I invoke layout inspector on NB6.0 in Visual Web JSF project and 
remove some components from design editor, layout inspector does not update
and removed components are still remaining. 
Then, close inspector window and re-invoke it, following exception are displayed and
inspector does not invoked.

Since the exception is coming from designer, assigning this to PeterZ for initial analysis.
Comment 2 Peter Zavadsky 2007-12-12 20:57:45 UTC 
Yes, this is as designed. The layout inspector is static, changing this to RFE.
Comment 3 Kenji Tachibana 2007-12-13 00:49:25 UTC 
Thank you for your evaluation.

I could understand that inspector is designed static, so it's OK to RFE to
create dynamic inspector.
However, it should not output the Exception, and it's a bug.
If this RFE is integrated soon, fine to wait,
but if not, please fix at least not to display the Exception soon.

If you need the other bug ID only for Exception, please let me know and 
I'll file it.
Comment 4 Peter Zavadsky 2007-12-13 01:14:45 UTC 
Oh, sorry, you're right, I must have been blind. The exception is a bug for sure, changing it back to a defect. After I
fix the exception, then I change it to the RFE.
Comment 5 Peter Zavadsky 2007-12-13 01:29:04 UTC 
I found that the NPE was already fixed (but unfortunatelly it didn't make it into 6.0), see issue #121239. So I am
changing the rest to the RFE (to make the DomInspector dynamic).
