I forgot to remove the EO from it's relationship before deleting it.
Once I did that, the EOs were deleted as expected.
With the right delete rules, you should only need to remove it from
the relationship.
I'm not sure why EOF would sometimes delete the EO and sometimes it
didn't - but, unhooking it before the delete solved the problem is
all cases.
I am not sure either.

I believe I've seen this issue before, but I don't recall what I'm
doing wrong...
I have an EO deleting itself from an editing context, but,
sometimes, only the EO's foreign key is getting set to NULL, which
has the same effect of deleting the EO. Other times, the row in the
database actually gets deleted.
The SQL going to the database sometimes is DELETE and sometimes it's:
UPDATE DEPARTMENT SET OID_EMPOYEE = NULL WHERE OID = ?...
Did I cross EC or something else bad?
Thanks,
Joe
