Hi there,
any ideas on what would cause the below exception? It's throwing an
IllegalArgumentException because excludeObjectFromPropertyWithKey is
not getting an instance of NSArray when attempting to obtain the
valueForKey of a toMany key.
is this a missing willRead[Relationship]() or something from the
deferred faulting?
excludeObjectFromPropertyWithKey calls 'valueForKey' which I can only
assume is returning null from the toMany key.
i.e., if the key is "toManyKey" and in my _EntityClass.java it's
found like this:
public NSArray toManyKey() {
return ( NSArray )storedValueForKey( ToManyKey );
}
Any tips on how to force storedValueForKey to retrieve the value?
with regards,

the key toManyKey is not a Array or one of its subclasses - unable to
remove the value.
