[SOLVED]: CoreData.. Relationship Not Persisting

I figured out what was going on.. Everything was working as expected excepted, I was adding the same element over and over again, instead of adding the new element. Copy and paste bug.

Subject: CoreData.. Relationship Not Persisting

I have a strange problem happening with my core data application. I am programmatically a entity to a relationship using the following steps:

1. Get a reference to the parent entities relationship set using the relationship accessor (entity.relationshipName).
2. Use the addObject method of the MSMutableSet to add the new relationship.



This all works great. When I move around in my application the bindings are there and everything is working fine. When I quit my application the changes are "saved" out to the presistant store and I receive no errors.


My problem is, when I re-run my application the link is gone. It is never saved out to the store.

I have even add a save call to the managedObjectContent at the end of my routine to insure that the changes are saved and I get no error.

Any advice or help would be great.

Thanks
