Don't worry you're not losing me. :) Basically, this is what's happening....
I have entity A1 with single table inheritance children A2 and A3
A1 has <->> B1, which is also passed on to the children
I'm creating a new A3 instance and a bunch of new B1 instances, I add
the B1's to the A3 relationship
I go to commit A3 and it tries to commit the B1's first, which explodes
because of the FK constraint to A3.
This isn't happening anywhere else so I'm not sure what's wrong (I'm
hoping it's not just luck), but basically I'm asking if A1,A2,A3 "own" B1 is
that the indication to EOF that B1 needs to be committed second, after a PK has
been generated and committed on A3
Thanks.
