Core Data troubles - not removing objects

Hi all,

I am pretty lost in the development of my app which uses Core Data and an SQLiteStore. I hope someone can point me towards the obvious point I am missing.

Given are two entities with bidirectional 1-to-1 relationships set to cascade upon deletion. The first entity contains strings and the other one contains binary data (like images and stuff). I set up two NSArrayControllers in IB and made the second one contain a set of the selected item from the first and also set the Deletes objects on remove checkbox in the Inspector.

My problem is that if I send the remove: or removeObject: message to the first NSArrayController and then query said item if it is isDeleted, I get true for the item itself, but false for the item connected through the relationship. I then manually removed the second object by sending a removeObject: message to it. Calling isDeleted now returns true.

All is nice except the SQLiteStore file does not get reduced in size. I guess that somehow I am doing something wrong and the objects do not get removed form the object graph at the next save: operation.

Is there anything obviously wrong or missing from my way of handling this? I could post some code if required.

Thanks,
ben
