Hi -
We've seen this too, but running on MySQL. It's really bizarre. The
EO's are built, the relationship set but then sometime between
saveChanges() and the raw SQL being sent to the DB it seems to forget
the foreign key in the relationship.
I've asked myself the same question too: how the hell did it get
passed model validation ?!!
Unfortunately we've never got to the bottom of it either...

Next exception:SQL State:23502 -- error code: 0 -- msg: ERROR: null
value in column "oid_person_type" violates not-null constraint
Any ideas how this could happen? The relationship and attribute are
marked as mandatory in the EO Model, so I'm not sure how this would
even pass through the validation?
It might be possible that this is related to load on the
application. I have 2 instance of this application, one which has a
much heavier load. This error is only occurring on this instance.
Any help is greatly appreciated,
Thanks,
Alan
