Mutable to-many relationship not observable

Hi,

I've a property digiDevices that's a to-many relationship. I've implemented the value write accesors (in addition to the read ones, which behave perfect):
- (void) insertObject:(DigiDevice *)digiDevice inDigiDevicesAtIndex:(NSUInteger)index {
	[digiDevices insertObject:digiDevice atIndex:index];
}

- (void) removeObjectFromDigiDevicesAtIndex:(NSUInteger)index {
	[digiDevices removeObjectAtIndex:index];
}

When I modify the relationship through mutableArrayValueForKey: the object is correctly removed, but no notification is send to objects observing the array. The KVC Guide states that I get automatic KVO by implementing these methods.
Is there something I did wrong?

Kind regards,

Remco Poelstra
