 The following code should work:

 {{{
 framework 'cocoa'
 class Foo
   attr_accessor :subject, :key, :another_key
   def initialize(subject, options={})
     @subject = subject
     @key = options[:key]
     @another_key = options[:another_key]
   end
 end


 def objects
   [Foo.new("test", :key => 'key', :another_key => 'another_key'),
 Foo.new("test2", :key => 'key2', :another_key => 'another_key2')]
 end

 controller = NSArrayController.alloc.init
 controller.addObjects(objects)
 controller.setAvoidsEmptySelection(true)
 controller.setPreservesSelection(false)
 controller.setSelectsInsertedObjects(false)
 controller.setAutomaticallyRearrangesObjects(true)
 controller.setSortDescriptors([NSSortDescriptor.alloc.initWithKey("subject",
 ascending: true)])
 }}}

 If instead you place a single item it works:

 {{{
 def objects
   [Foo.new("test", :key => 'key', :another_key => 'another_key')]
 end
 }}}

 Or if you make the second item have a different set of keys...

 {{{
 def objects
   [Foo.new("test", :key => 'key', :another_key => 'another_key'),
 Foo.new("test2", :another_key => 'another_key')]
 end
 }}}

 This it works again...
