Hi, I have a bidirectional one to one relationship between two entities like this:
Foo <-> Bar, and Foo has a subclass FooSub. All entities are concrete. Sometimes when I set the inverse relationship it's like this aBar.toFoo = aFoo, and this works fine, but when it's linking back to the subclass, aBar.toFoo = aFooSub, it fails with a validation error: toFoo is not valid, dangling reference to an invalid object = null. I would have thought it would be OK for the relationship to point to an instance of FooSub shouldn't it? After all, it is a subclass of Foo. Or do things work differently for subclasses in Core Data? If so, how should I work around this problem?
