fabrizio giustina closed DISPL-237:
-----------------------------------
Resolution: Fixed
Fix Version: 1.1
the first NPE should now be fixed in CVS, no clue on how the second exception
could be generated.
The current code in HEAD is not very stable, but please let me know if you have
a change to give it a try and see if the problem is solved.
