Description Mikhail Kondratyev 2006-09-21 13:10:29 UTC 
Sometimes when you edit BPEL code sources disappear without any visible reason.
Many engineers here have seen this but exact scenario is not known.
Steps to reproduce (with this steps bug can be reproduced with relatively high
probability):
 - create new sync sample
 - switch to sources
 - do the following quick:
 - type <assign>, then type </assign>
 - after assign type <copy wait a bit  - <copy will disappear
The attached flash demo shows this scenario

Could this bug have the same root cause with IZ 82295?

bug 82295
Comment 4 Denis Anisimov 2006-09-22 10:46:26 UTC 
This was a problem in validation logic.

Validators used start/endTransaction() methods for locking OM while they
are performed validation.
The problem that endTransaction() always flushes OM into document.
So when validation was performed while editing it flushes its last state to 
swing document. It looks like lost changes in editor.

Not situation is corrected via obtian READ lock on OM.
This lock is never flush OM into document so there no any problem with 
described behavior.
