Hi there,
Yeah, looks like CAY-796 [1] to me. I could swear we fixed it, but
looks like we did not. Ok, adding that to a TODO list...
In the meantime try to check the "Use Shared Cache" checkbox in the
Modeler - this would hopefully take care of the problem (and probably
improve your performance if you could live with a bit of object
caching in your app).

on Cayenne 2.0.2.
This seems to happen always for the same Local EJB, while other Local
EJBs that use Cayenne in the same way seem to work. From a previous
email, it seems this has something to do with the serialization of the
objectStore.
What can I do to get rid of this ?
Thanks,
