Hi Jeremias,

This is also known as CAY-1009:
http://issues.apache.org/jira/browse/CAY-1009

I tried patch from there (and it looks like yours) but there WERE side
effects (I listed them in JIRA). At the moment I was forced to make the
relationship non-mandatory in my project (and validate in different ways). I
would really like to get it fixed, but I haven't found time for that yet...
Please watch the JIRA to be notified of the updates

Regards,
Andrey

> - I have an (abstract) entity A and two subentities/subclasses A1 and A2.

> Now, if I create an instance of A1 and use addToB() to add a B1 instance,
