I did build RubyCocoa myself, because at the time the binary install  
didn't work; I had to remove some deprecated constants from  
framework/src/objc/cocoa/rb_NSGraphics.m and rb_NSSavePanel.m in order  
to get it build. After that, it works fine, untill I tried my hands on  
Cocoa Bindings, new in Panther.

My dummy-app is the demo-project found at:

  	http://www.macdevcenter.com/pub/a/mac/2004/04/06/cocoa.html?page=1

I decided to do it with ruby and then the Book-class will be:

	def Book < OSX::NSObject
    		attr_accessor :title
    		attr_accessor :author
	end

All fine, untill I try to run the app from Xcode, which shows this  
error:

/Users/hvs/tmp/bibliotecha/build/bibliotecha.app/Contents/Resources/ 
rb_main.rb:19:in
`NSApplicationMain': NSApplicationMain - NSUnknownKeyException -
[<Book 0x4f2540> valueForUndefinedKey:]: this class is not key value
coding-compliant for the key title. (OSX::OCException)
  from  
/Users/hvs/tmp/bibliotecha/build/bibliotecha.app/Contents/Resources/ 
rb_main.rb:19

Am I missing something?
