Description _ pcw 2005-02-23 22:37:47 UTC 
I opened web.xml in text mode side by side with
the visual config editors for sun-web.xml.

Then I created a new empty line right below
<web-app...>, typed "<servlet>" and got this
exception popup as soon as I typed the closing ">".

Annotation: Exception occurred in Request Processor
java.lang.IllegalStateException: BaseDocument.write()

Comment 2 _ pcw 2005-02-23 22:43:10 UTC 
Upon checking my log, it appears the exception that popped up actually
followed another one that was displayed in the log only and had more
information.  See second attachment and disregard first one.

Comment 4 Milan Kuchtiak 2005-02-24 08:49:52 UTC 
I noticed that as well few times during editing.
The exception is caused by BadLocationException from
CloneableEditorSupport:getInputStream() method.
However today I am not able to reproduce that.

Basically, we call the CloneableEditorSupport:getInputStream() method
(after couple of changes in DD editor) to get the data model and to
synchronize with the graphical view.

Jarda, can you help how we can prevent the BadLocationException ?
Comment 5 Jaroslav Tulach 2005-02-24 12:10:08 UTC 
I doubt I can prevent it, it can be thrown by anyone. I've just add 
better debug messages to know who is causing the exception.

Comment 6 Milan Kuchtiak 2005-03-01 15:20:26 UTC 
I was not able to reproduce the issue any more.
It (most likely) fixed by fixing the issue 38853.
