Same results more-or-less:
I set the secondary NSArrayController to be bound to the master with
arrangesObjects and @distinctUnionOfObjects.Genre
I wish there were an example of a iTunes-like table with say 4 or 5 columns
and then two filtering columns, and a final table showing the filtered
results with the same 4 or 5 columns of filtered data. That is all I am
trying to make it do.
