title: CakePHP read in hasMany through relationship
body: <p>Trying to display related data from a hasMany through table. It's finding the joinModel but not extending to the other table's data.</p>
  
  <p><strong>Item Model</strong>:</p>
  
  <pre><code>class Item extends AppModel {
  public $name = 'Item';
      public $belongsTo = array('Category');
      public $hasMany = array('GroclistItem');
  }
  </code></pre>
  
  <p><strong>Groclist Model</strong>:</p>
  
  <pre><code>class Groclist extends AppModel {
  public $name = 'Groclist';
      public $belongsTo = array('Category');
      public $hasMany = array('GroclistItem');
  }
  </code></pre>
  
  <p><strong>GroclistItem Model</strong>:</p>
  
  <pre><code>class GroclistItem extends AppModel {
  public $name = 'GroclistItem';
      public $belongsTo = array('Groclist', 'Item');
      public $useTable = 'groclists_items';
  }
  </code></pre>
  
  <p><strong>GroclistController View Action</strong>:</p>
  
  <pre><code>public function view($id = null) {
      if (!$id) {
          $this-&gt;Session-&gt;setFlash(__('Invalid list', true));
          $this-&gt;redirect(array('action' =&gt; 'index'));
      }
      $this-&gt;set('groclist', $this-&gt;Groclist-&gt;read(null, $id));
  }
  </code></pre>
  
  <p><strong>Debug of $groclist</strong>:</p>

  <p>I would like the GroclistItem array to display the item data which should be a grocery list item such as Diet Coke or Soap. It's finding the correct associations in there.</p>
