Now that I know how to get instruments to track retains and releases, I can see
what is happening to my entity. I'm still uncertain how to interpret the
results, but I see two strange things in the history of the object being
deleted:
1) It has a reference count of 3 after all the deletion stuff has finished
2) Whenever I do [NSTreeController selectedObjects] I seem to end with an
additional reference count. Is that expected?
In the end, I'm struggling to see if this could be the cause of my "CoreData
could not fulfil fault" bug. Since I can't reproduce this on my development
machine (10.8) and it only shows up on 10.6.8, it's proving difficult to track
down.
Anyone have any other ideas? Or can anyone see the problem in the history of
the object dumped below?
Yours in abject frustration,
Martin
