Comment 1 Samaresh Panda 2007-04-13 21:25:27 UTC 
I'm not able to reproduce this. Are you able to reproduce this consistently? In
any case, I'll take care of the NPE.
Comment 2 tonybeckham 2007-04-16 17:24:31 UTC 
I can reproduce this with the following system:
NetBeans IDE Dev (Build 200704091800)
1.5.0_07; Java HotSpot(TM) Client VM 1.5.0_07-87
Mac OS X version 10.4.9 running on i386
en_US (nb); MacRoman

I also get this exception when opening the XML document the second time:
java.lang.AssertionError

This assertion error looks similar to the other error message, but like I said I
do get the npe when doing the last step and it is the same as the one posted.
Comment 3 tonybeckham 2007-04-16 17:49:26 UTC 
I didn't realize that 2 errors were posted originally, so I can say that I can
reproduce every time.
Comment 4 tonybeckham 2007-04-16 20:21:14 UTC 
I am getting exceptions very frequently once the steps to reproduce are
performed.  Even just switching between source, schema, and design views throws:

Also, creating a new web project throws this exception when you click finish:

Comment 5 tonybeckham 2007-04-16 20:26:25 UTC 
Restarting the IDE will allow you to create new projects and files without
exceptions, but once you run into into one, almost any view or file
switch/open/new throws exceptions and you must restart to be able to use at all.
