When reopening a Cocoa class, you should not overwrite initialize and if you were to do it anyway, don't forget to call super and to return self.
The Cocoa way is to create your own initializer to end up with something like DuplicateCounterTextField.alloc.initWithDuplicate

Also, remember that when initializing a Cocoa class, you need to do DuplicateCounterTextField.alloc.init

I'm sure this is an elementary question, but I have the class below. In IB, I set several NSTextField controls to this class. Everything works in the blah, blah, blah part, but strangely enough the

puts "initialize dctf"

never seems to be called. Any thoughts as to why?

require 'strings'

class DuplicateCounterTextField < NSTextField
 include Strings

 attr_accessor :splitter, :completions
 attr_accessor :wordCount, :duplicateCount

 def initialize
   puts "initialize dctf"
   @splitter = /\W+/
   @wordCount = 0
   @cachedWordCount = 0
   @duplicateCount = 0
 end

 # blah, blah, blah working code

 def textDidChange(notification)
   words = stringValue.split(@splitter)
   @wordCount = words.length
   @duplicateCount = @wordCount - words.uniq.length

   if delegate.respond_to?('controlCountDidChange:wordCount:duplicateCount:')
     delegate.controlCountDidChange(self,
                                  wordCount:@wordCount,
                             duplicateCount:@duplicateCount)
   end
 end

 # etc.
end
