No. It's bound to a property of some object. Please be precise;
NSMutableArray isn't KVO-compliant, so if you have indeed bound to a
property of an array then you're going to have problems.
So please describe the ordered collection property to which you've
bound your array controller. Are you exposing it as an
NSMutableArray? Just an NSArray? Or are you using the ordered
to-many accessor methods?
