Description Mikhail Kondratyev 2007-03-01 17:23:30 UTC 
Steps to reproduce:
 - create an XML document
 - type & and then any letter after an opening xml tag. For example:
<xml-tag> &h
</xml-tag>

 - at the moment when you type 'h' in this scenario NPE will be thrown:
java.lang.NullPointerException

Comment 1 Samaresh Panda 2007-03-01 18:04:11 UTC 
Which build are you using? The stack trace and the source do not match. Please
try this with a newer build. I'm not able to reproduce.
Comment 2 Mikhail Kondratyev 2007-03-01 18:14:25 UTC 
I'm using Milestone 7b build.
We will switch as soon as Beta testing is over and I will try to reproduce once
more.

With Milestone 7b several engineers could reproduce it.
Comment 3 htt 2007-03-01 18:17:09 UTC 
Reproducible with 070301_5....

Create an empty newXMLDocument.xml.
Simply type <xml-tag> &h => exception below

java.lang.NullPointerException

Comment 4 Samaresh Panda 2007-03-01 18:48:03 UTC 
OK, I see it now. I was using the snippet as in the initial description, that is:
<xml-tag> &h
</xml-tag>

Where as, the trick is:
<xml-tag> &h
