Create a new object 2. Create a relationship between the new object and an existing object 3. Turn the new object into a fault before it is officially inserted 4. Save changes So if you're getting this exception, you need to be more careful about using the -refreshObject:mergeChanges: method, because the code is most likely misusing it. One way to fix this is to never refresh an object that has a temporary object ID.
