When a EO object is saved

Is there a way to stop EOEntityClassDescription from validating
relationships? When it validates a relationship it causes a select to
happen. We noticed this because we have a couple of expensive
relationships
select wise. It is also kind wasteful to have 5 or 6 selects fire
because
you changes a single property.
It needs to ensure that the object is valid. These are probably
mandatory relationships and it is verifying there are members. You
could try implementing
public Object validateValueForKey(Object value, String key)
to not call super for these keys if you think there is no reason to do
so.
A probably better option is to NOT model these relationships, and just
fetch / manage them as needed.
