From: hvs1@... (Harry) Date: 2004-07-14T18:17:26+09:00 Subject: 'solved' (was: Re: [RubyCocoa] Cocoa Bindings? (cont.)) 'solved' but not really ... just a track I hope ... If I add the ObjC files for class Book as listed on the tutorial-site to my project, and have the ruby-class Book inherit from that, it works ... Book.rb: ns_import( 'Book' ) class Book < OSX::Book #attr_accessor :title #attr_accessor :author end I'm not knowledgeable of RubyCocoa intrinsics, but this quirck tells me somewhere along the way the KVC-resolving gets confused, as apparently the accessor-methods for the keys do not translate or map to the ObjC wrapper and core object for Book ... it might just be a naming-question ... ? any comments welcome, Harry
