Hi Slawomir,
Is it possible that you try if the same problem occurs when using the DBStore (H2 is the easiest way to set up) instead
of the HibernateStore? Then I could see better whether the problem is caused by a particular store or whether it can be
a bug in the CDO core.
Cheers

I have worked with CDO/Teneo with many models in one server which reference eachother, and it worked. So my guess is
that it might be related to the Lob part, have you tried other types of ereferences?
