Okey, I've solve the problem !

It's very simple, I've only load the in NSManagedObjectModel the mom file represent the modification base, not the main model... Now I load all mom file and it's work !

Thanks all

Shouldn't cause a problem.

I thought the collection classes were smart and treated -valueForKey:
by sending each object in the collection -valueForKey: and compiling
the results in an object arranged in the same way as the original.
That way you could have an array of strings and do something like
[myArray valueForKey:@"length"] to get an array of lengths
corresponding to each instance.

Sort of. Depends on the collection class. The behavior you describe works for NSArray (and NSSet, IIRC). For NSDictionary, the rules are slightly different:
...

If key does not start with [EMAIL PROTECTED], invokes objectForKey:. If key does start with [EMAIL PROTECTED], strips the [EMAIL PROTECTED] and invokes [super valueForKey:]with the rest of the key.

...


Which is, frankly, a bit goofy and, thus, the primary reason why I would avoid using -valueForKey: on a dictionary.
