Hi!

What you could try is to prevent your editing context from receiving 
the ObjectsChangedInObjectStoreNotification by unregistering it editing 
context from the notification center like so (I guess this is WO 4.5 
code, check the name of the notification):

NSNotificationCenter nsnotificationcenter = 
NSNotificationCenter.defaultCenter();
nsnotificationcenter.removeObserver(editableContext, 
"EOObjectsChangedInStoreNotification", 
editableContext.parentObjectStore());

I played around with this a while back. What happened was that the 
second editing context to commit succeeded and overwrote the changes 
made by the first one. It even overwrote attributes that were not 
modified locally with the value previous to the first commit. I.e. 
instead of the desired "first wins" situation I got a "last wins" 
situation. Thus I went off to other solutions.

I leave it up to you to determine what harm could stem from disabling 
this notification.
