I agree that there ought to be links from each class to the corresponding page in that reference.
> I've run into similar questions to this before, but the particular motivating example at moment is as follows. In a Table, I want a pop-up cell for a given column. The columns in the table are all bound to an NSArrayController which is in turn backed by CoreData. The list of possible values for the column with the pop-up is also meant to be bound to another NSArrayController which is also back by CoreData. I have not yet been able to get this to work.
There's documentation for this sort of arrangement in the Cocoa Bindings Programming Topics:
http://developer.apple.com/mac/library/documentation/Cocoa/Conceptual/CocoaBindings/Tasks/onerelation.html
Also, check here for more examples and discussion:
