Description tonybeckham 2008-04-01 18:39:44 UTC 
Problem:
Upon closing a schema file opened in the editor NPE is thrown.  Doesn't happen for other file types only XSDs.

Systerm:
Product Version: NetBeans IDE Dev (Build 200803302302)

System: Linux version 2.6.22-14-generic running on i386; UTF-8; en_US (nb)

Steps:

Comment 2 tonybeckham 2008-04-01 18:41:36 UTC 
To reproduce, must be in schema view, does not happen when in DV or source view.
Comment 3 Samaresh Panda 2008-04-01 19:16:27 UTC 
Sounds like there has been some recent changes elsewhere in the platform that causes this regression because this was
not a problem earlier.
Comment 4 Mikhail Matveev 2008-04-01 19:23:54 UTC 
Yes, it must be due to some very recent changes.
Comment 5 Samaresh Panda 2008-04-01 19:52:47 UTC 
Just curious, was it an issue in last night's build?
Comment 6 Samaresh Panda 2008-04-01 20:19:37 UTC 
I'm not sure why componentDeactivated() gets called after componentClosed(). In any case, please try the new jar; copy
it to xml2/modules in a trunk build and verify.

The patch works for Vista, I will try Mac as well.  Do you see any chance of other issues arising from this patch?

Comment 9 Samaresh Panda 2008-04-01 22:26:53 UTC 
No, there should not be any other implications.

Comment 11 tonybeckham 2008-04-01 23:24:36 UTC 
Patch works on linux so I say go for it.  It needs to be in the 6.1clone branch as well.  I went back to see when this
behavior began and can say that in the long period last week where we only had one build it was fine (build
200803251204) the few builds since then have the problem.  I know it's moot now just FYI.
