-insertObject: is the reciprocal of deleteObject: You can use it
to cancel a deletion.

I have a tree of managed objects with parent <--> child

parent is deleted.
But sometimes, after deleting a parent, I need to restore a deleted
child under a new parent. So I set the new relationships and also
send
[managedObjectContext insertObject:deletedObject] ;
It appears that -insertObject: "cancels" the object's previous
Cascade-deletion. It definitely does not persist as desired if I
don't to this.
But of course since my situation is rather odd it is not covered in
"Creating and Deleting Managed Objects" of the "Core Data
Programming Guide". Is what I'm doing OK?
Thanks,
