No idea - why don’t you put a breakpoint in your KVO handler and see where it’s being called from, my guess would be the end of the event loop. If you want it earlier try calling the method to process pending changes, or remove it from the relationship yourself as well as deleting it. > > Also commitPendingChanges: does not appear to be in any method of the Cocoa > frameworks. processPendingChanges:, it’s on NSManagedObjectContext > > Richard Charles > ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

What “event” does propagatesDeletesAtEndOfEvent refer to? An event loop, some type of Core Data event? The documentation as I read it is unclear. Also commitPendingChanges: does not appear to be in any method of the Cocoa frameworks.
