Hi Ricardo,
you mean Message.mimeType is a flattened attribute to
Message.mimeContent.mimeType? An this is causing the unwanted cascade
delete?
Sounds scary...

Thanks Chuck... You lead me to the problem.
My Message entity has a mimeType property derived from
mimeContent.mimeType. So it seems that is the reason why EOF is
deleting the mimeContent to-one when I delete the parent Message.

Is there another relationship with Owns Destination or Cascade
Delete set on it. Those are the only things that I can think of
that would make EOF delete an EO. Could it be happening in your
code?

Hi,
When I remove a child from a many-to-many relationship in the
parent and delete the child I see EOF deletes the child in the
database and the corresponding record in the join table. That's
great. However, the child object has a to-one called mimeContent
and I'm also seeing a delete for the destination object:
DELETE FROM MIME_CONTENT WHERE MIME_CONTENT_ID = ?" withBindings:
1:26954(NeededByEOF0)
1 row(s) deleted
I'm trying to figure out why this record is being deleted. I
already checked the "Own Destination" for the mimeContent to-one
and it's not set. The "Delete Rule" is set to "No Action". So I
don't quite understand why it's getting deleted. I don't want it
to be deleted.
Any ideas?
Thanks,
Ricardo
