Core data model - binding question

Subject: Core data model - binding question

I am trying to build an iTunes-like browser interface: first column selection determines the values displayed in the second column, etc. This is easily accomplished through the use of the contentSet binding of the NSArrayController. The controller is hooked up to a core data model; to select the passages of a book I logically bind the passages NSArrayController to the selection.book of the book NSArray controller. Now I have a slight problem. My core data model is Books <--->> Passage <<--->>Topic. The iTunes-like table set follows a different order: topic - book -passage. Now I cannot really use the contentSet binding, for ther is no "direct" relationship between books and topics... Is there a smart way to solve this problem? I tried to bind the book contentSet to the passages array controller with selection.passages.book key, but the app crashed... Thanks a lot in advance, Davide _______________________________________________ Do not post admin requests to the list. They will be ignored.
