Kai,
If you get an exception, why not share the stack trace with us? :P
What you're doing sounds like one of the most basic use cases of CDO.
Hence I'd be surprised if you uncovered a severe problem in this area
that nobody else complained about, yet. But it's still possible! I
suggest you file a bugzilla and give all the information that can help
us track it down (incl. the used models if they're not confidential).
Cheers

Simon,
Can you transfer this discussion to a new Bugzilla? Thx ;-)
