Replying to Rich's post on the KVC methods to add to get binding compliance http://lists.macosforge.org/pipermail/macruby-devel/2008-September/000563.ht... I'm getting the same error as per this thread, tried adding Rich's KVC methods to my StaffList.rb (which is probably MyDocument.rb for most people but I think its an awful name) and the error didn't go away. The project src is posted on github: http://github.com/drnic/hillegass-macruby/tree/master/RaiseMan I get a number of the following errors: 2008-12-30 09:33:16.934 RaiseMan[66636:10b] [<NSTableColumn 0x10e1fa0> valueForUndefinedKey:]: this class is not key value coding-compliant for the key displayPatternValue1.
