title: Bindings for custom views for NSCollectionViewItem
body: <p>I've got a <code>NSCollectionView</code> bound to my array of model objects, the <code>NSView</code> prototype to render items of the collection view is set up to use my custom <code>NSView</code> subclass.</p>
  
  <p>At runtime a (generic) view is shown/instantiated in the collection view for each array element, all good.</p>
  
  <p>However, I just can't figure out how to get to my array objects from the individual view instances to render the actual data that's specific to each element in the array.<br>
  I.e. how are we supposed to hook up data to the <code>NSView</code> prototype that is used to configure a 'cell' in the collection view?</p>
  
  <ul>
  <li><p><strong>Outlets</strong> don't seem to work for that particular view; they're all <code>nil</code> at runtime.</p></li>
  <li><p><strong>Bindings</strong> don't work with a vanilla <code>NSView</code> (apart from <em>hidden</em> and <em>tooltip</em> bindings for vanilla views..) - and we cannot add new bindings that would show up in IB for our <code>NSView</code> subclasses, can we?</p></li>
  </ul>
  
  <p>Any hint appreciated!</p>
