title: NSWindowController windowDidLoad not called
body: <p>I have a simple Cocoa app using a NSWindowController subclass.  In the nib I have set:</p>
  
  <ul>
  <li>File Owner's class  to my NSWindowController subclass</li>
  <li>The 'Window' outlet of the File's Owner to the main NSWindow in the nib.</li>
  </ul>
  
  <p>The init method of my NSWindowController subclass is called (I call super), but not matter what I do windowDidLoad is never called.</p>
  
  <p>I must be missing something obvious, but for the life of me I can't figure out what it is.</p>
