I was thinking more of having A and B each have the other PK as a FK.
Huh... Have you ever done this? Anyone else?
Though this may irritate EOF when it tries to look up inverse
relationships. You can tell EOF what to do by implementing String
inverseForRelationshipKey(String relationshipKey) on A and B.
Yeah, sounds like this might end up kicking me in the ass. Especially
since I can't override client side class descriptions, so I would
have a discrepancy between what EOs and class descriptions see as
inverse relationships. Not sure I like this idea, it might have
unforeseeable consequences, no? More work...
But, to come back on the original idea, what do you think of putting
a uniqueness constraint on the FK? Would that somewhere somehow screw
the object graph up beyond repair?
F
though, after thinking about it some more, I don't really *need*
this. I would like it though :)
