Yes, I probably have a lot of that going on too.

I want to make sure this is not harder than I think.
My Foo class has not overridden -awakeFromFetch.
My Bar class does this…
- (void)awakeFromFetch
{
[super awakeFromFetch] ;
NSDictionary* exids = [[self localStoreManager] exidsForBar:self] ;
[self setIvarExids:exids] ;
}
-localStoreManager is an object which accesses a "local" persistent store,
which it identifies per the Bar object's -managedObjectContext. Thus, we get
'exids' from this other store and cache it in ivarExids which is, as the name
implies, a regular instance variable.
With this, I conclude that I am clean as far as not setting relationships in
-awakeFromFetch. Are there other back doors which I haven't checked?
