How is this happening? Via code? or Via the NSArrayController (add: or insert:)? In the latter case the docs say, "Beginning with Mac OS X v10.4 the result of this method is deferred until the next iteration of the runloop so that the error presentation mechanism can provide feedback as a sheet." > Calling a controller 'fetch:' immediately after inserting the managed object > into the managed object context does not help.

If the action has been deferred as described above, you are mostly out of luck. You could chance manually turning the runloop but it is fragile and generally recommended against.
