Just the default constructor, which implicitly calls super. All the model classes are EOGenerated. Any other ideas to check?
Thanks.

Next, I iterate through the results adding the object from the relationship to a NSMutableArray for display. It is at this point that, periodically, the relationship returns null instead of the object. This is a test system so there is only one entity in the database and this relationship should definitely return an item. If I do this in reverse... I preform the fetch on the relationship's entity and use key paths in the qualifier back to the master entity it seems to go away (this is hideous).
