"cannot do a deep fetch on entity … with parent … because they are stored in different databases."
IIRC EOF does not support inheritance across databases.

Hey guys,
I try to model an inheritance between two different models and two databases.
I have the parent entity modeled in "model1" and stored in "database1" and the subentity in "model2" and "database2".
The subentity has additional attributes and additional relations.
Now, when I try to run the application, the following exception appears:
IllegalArgumentException: _buildNodeListWithParent: cannot do a deep fetch on entity '<SubEntity>' with parent '<ParentEntity>' because they are stored in different databases.
Where <SubEntity> is the name of the subentity and <ParentEntity> the name of the parententity.
Does anybody have an idea?
Thanks.
