All the reasons you and Ben have been discussing is exactly why I find it much easier to just have my own unique identifier. The downsides are: 1) takes a little more space in the store (and on disk and in RAM) 2) is slower to fetch against vs using the permanent NSManagedObjectID. I'm curious why you are switching. I have thought about doing the same, but it just seems like way more work for little benefit. -- ____________________________________________________________ Sean McBride, B.
