 I am new to MacRuby so I apologize if I have this wrong.

 I am trying to access the patch values of a quartz composer controller
 object and I am running into some errors.

 Here is a summary of the code:

 class AppController

 attr_accessor :testButton, :myQCView

 def awakeFromNib

         @test_btn = false

         puts @myQCView.is_a? NSObject
         @myText.setStringValue("this is my value")
        @myQCView.setValue(txt, forKeyPath:"patch.text.value")
         puts @myQCView

   end

 # a test button
         def testButton(sender)
                 if @test_btn
                         @testButton.setTitle("test button")
                         puts "test button activated"
                         @myText.setStringValue("test content")
                         @test_btn = false
                         image =
 @myQCView.valueForOutputKey("quartz_image")
                         puts "this is the image " + image
                         if image
                                 puts "got the image"
                         end
                 else
                         puts 'test button Stopped'
                         @testButton.setTitle("stop test")
                         @test_btn= true
                 end
         end

 The error message I get is:
