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:
