I have a problem with two CMR relations and overlapping fk fields, where one relation is nullable, but the other is not:
There are three tables
workcenter, pk = (woce_client, woce_index)
workcentertype, pk = (wcty_client, wcty_index)
workstep, pk = (wstp_index)
workstep has a many to one relationship with workcentertype, which is not nullable
workstep has a many to one relationship with
workcenter, which is nullable
workstep maps woce_client and wcty_client to only one column wstp_wcty_client in the workstep table.
If I load an entity bean, where the workcenter is null, JBoss tries to set also also the other part of the
foreign key wstp_wcty_client to null.
But this field must not be null because it is also part of the foreign key to workcentertype.
Any hints how to handle this situation are appreciated.
