Hi, Is it possible to use bind values using macruby? I've been working through Hillegass' Cocoa Programming For Mac OS X, converting the exercises to MacRuby. I've hit a big of a snag in the RaiseMan exercise though. It uses an NSArrayController as a binding for a table view. There is then a NSDocument called Person which is bound to provide the values for the table. When I try to run this, I'm getting an error: this class is not key value coding-compliant for the key employees I've tried a number of different ways to make employees respond: attr_accessor :employees and also using a manual setter (in two different ways): def employee=(val) end def setEmployee(val) end Neither seem to work. Am I doing something wrong? Is this unimplemented? I've looked at a RubyCocoa implementation of this exercise, and they just completely skip the NSArrayController and just set up a data source. Thanks for any help. Brad
