mmalc and I had a short exchange on this off-line.
it might be more efficient to consider either subclassing
NSArrayController and modifying arrangedObjects to return the subset
(mmalc's suggestion)
or
add a new set of indexed accessors to your model that return a
maximum value for the countOf<Foo> (sigh, can't remember the exact
selector, check the doc) of the maximum number of items you want.

in a word "NSValueTransformer".
have a value transformer that takes the array, and only returns
the first x objects.

Hi there,
I have a problem here and I am not sure I can handle it easily.
I have to array controllers, one's content set is bound to the
selection of the other. this is all working fine, i have it all
set up to show the bound data in a table view, which is fine too.
now what i need to accomplish is to have a third array controller
that is bound to the selection of the first one as well, but only
displays the first 15 entries of the given selection. so say the
selection in arraycontroller 1 has 35 entries, i only want this
new arraycontroller3 to handle the first 15 elements, while i
want arraycontroller2 to handle all 35. is this possible? how
should i try to do it?
