[MacRuby-devel] NoMethodError (ib_outlets)

Hi I'm giving my first MacRuby application a shot, and I'm sort of blind to be honest :) I've added a NSWindowController, attached it to my window, saved the classes in Interface Builder, but when I build and run my application, I get a NoMethodError for 'ib_outlets'. My controller inherits from NSResponder. The stranger thing is, I guess, when I remove any code referencing ib_outlets, the same error is raised again. NoMethodError. Any advice? What class defines ib_outlets? Am I doing it completely wrong? Thanks. -- Rob
