[Rubycocoa-talk] NSProxy doesNotRecognizeSelector:copyWithZone:

[Ferhat A. <fer...@ya...>]

Hi,


I'm trying to run an activerecordsupport application. I have added an ActiveRecordSetController ArrayController in IB and set the class name properly (in my case ProductProxy).


here my simple controller code (inspired by the blog article by Eloy Duran)





require 'osx/cocoa'




class CNController < OSX::NSWindowController

  kvc_accessor :products

  

  def init

    if super_init

      ActiveRecord::Base.establish_connection({

       :adapter => 'mysql',

       :host => 'localhost',

       :username => 'root',

       :password => '',

       :database => 'xyz_development'

      })

      @products = Product.find(:all).to_activerecord_proxies

      return self

    end

  end

end




I have generated product.rb and product_proxy.rb using the handy generate.rb script. 


So, the error message I get is the following


[Session started at 2008-01-18 22:51:02 +0100.]

/Users/ayaz/Projects/CNClient/build/Debug/CNClient.app/Contents/Resources/rb_main.rb:24:in `NSApplicationMain': NSInvalidArgumentException - *** -[NSProxy doesNotRecognizeSelector:copyWithZone:] called! (OSX::OCException)

	from /Users/ayaz/Projects/CNClient/build/Debug/CNClient.app/Contents/Resources/rb_main.rb:24




The Debugger has exited with status 1.The Debugger has exited with status 1.


Any idea?


Thanks!
Ferhat
