Tamar,
Eike is having hardware problems and likely to be slow in responding
until that's fixed. If you could build a self-contained test case and
open a bugzilla, he could try it out to reproduce the problem.

Tamar,
in addition to what Ed said: could you please try a newer version (CDO
4.0 or 4.1M7 which are part of 3.7 or 3.8M7, respectively). The 3.0
branch is already out of maintenance.
Cheers,
Stefan

Hi,
I'd also strongly suggest to start working with CDO 4.1 because even 4.0 will be out-of-maintenance next month with the Juno release. Please also note that our downloads page lists the recommended Platform and EMF versions per CDO stream. We know that some users deploy CDO in different combinations but officially that's not covered by our free support here. If you want to write test cases to speed up our analysis/fixes please have a look at our test bed with ~2500 test cases and a number of pre-generated test models that should cover all imaginable model scenarios.
Cheers
