The objective is for me to be notified when "toOne.attribute" changes (either by toOne changing or by the attribute changing).
Surely what I am doing is not getting the NSManagedObject to observe itself, but rather the observer is self and the "observee" is the to one relationship and it's attribute. If I made it [toOne addObserver:self forKeyPath:@"attribute" options:0 context:NULL], then I would have to separately keep track of when toOne changed, and update the observers, and also this is a simple case - sometimes I need to do "toOne.toOne.attribute". Or maybe I'm missing something in how KVO works with key paths... Gideon On 09/08/2010, at 9:24 PM, Michael Swan wrote: > Gideon, > It looks like you have an NSManagedObject that is observing itself.
