I put together an Objective-C version of this same thing and checked it into the github project for comparison. It works. I'm sure there's something different in how I'm using it, but I can't see what. The project is at:

git at github.com:sxross/MacRuby-Array-Cocoa-Array-Binding.git

That's both MacRuby and Objective-C. Any pointers to my blind spot are appreciated :)

It's bound to LightboxController.managedObjects:number. The managedObjects collection contains a collection of Lightbox objects, that have a number (Fixnum, when examined) and a title (string). The title displays fine, but the number always displays as 1. Changing the number field to a string and removing the NSNumberFormatter produces the correct display, but of course, the sort order is string ordering rather than numeric.
