OK, so the filtering should be done in arrangeObjects, not in
arrangedObjects, and that makes so much more sense.
And what's worse, I've been to mmalc's site dozens and dozens of
times and I forgot about that one.
Thanks!

I've got a subclass NSArrayController whose contents are displayed

this list differentiated by various criteria. I'd like to let my
users filter that list and show only the type (or types) that they
want.
My first attempt was to use my subclass and overwrite
arrangedObjects: and filter there. However, because the list of
objects is rather long, this resulted in poor redraw performance
and jerkiness during scrolling.
For various reasons (mostly performance and stability), I'd like
to keep all the objects in the array and simply filter them. Is
there a way to do this that I'm missing?
Have you looked at mmalc's page?
<http://homepage.mac.com/mmalc/CocoaExamples/controllers.html>
Filtering Controller
Shows custom array controller that interacts with a search field
(NSSearchField) to filter the displayed content of a table view.

Thanks!
