What is the best the data source for a table view in a document window? The candidates are…
(1) Category of the document. This is the way it is done in the WithoutBindings ("With and Without Bindings") Apple sample code. But it seems like too much "view-ish" code in the data model, particularly when my document class is also used in a GUI-less command-line tool, which has no need for this code.
(2) Separate, standalone object. Fancy housekeeping is needed to avoid retain cycles, and crashes in corner cases as the document window is closing.
(3) Category of the window controller. Probably not a bad choice, except that my window controller for this multi-tabbed window is already huge.
(4) Category of the table view itself, assuming that it is subclassed. Seems like a logical division. No worrying about whether table view or its data source gets deallocced first. Access the document via [[[self window] windowController] document].

I've used (2) but think I'm going to switch to (4). Any important considerations I've overlooked?
Thanks,
Jerry
