Mikhail, please provide more detailed steps to reproduce.
Comment 2 Mikhail Kondratyev 2006-09-25 08:58:50 UTC 
Unfortunately I can't provide more details. The only chance is that the
developer will have a look at the stacktrace and probably will identify the
problem. In case this does not help - we can close the bug.
Comment 3 Vladimir Yaroslavskiy 2006-09-25 13:37:15 UTC 
How to reproduce the issue.
- start ide, create TRS project
- open bpel diagram, close ide
