title: Cannot display comments with CakePHP Comments Plugin
body: <p>I have the <a href="http://cakedc.com/downloads/view/cakephp_comments_plugin" rel="nofollow">CakePHP Comments Plugin</a> set-up correctly, I believe.  I've followed the poorly-written instructions <a href="https://github.com/CakeDC/comments/blob/master/readme.md" rel="nofollow">[here]</a> to the point where it's requiring me to login to add a comment.  When I click "add a comment", it gives me the title and body form fields.</p>
  
  <p>It's even submitting and saving the data just fine.  Then, the data comes across when I <code>debug($article);</code> - I see the comment(s) for that article in the data.</p>
  
  <p>But - the only thing that appears when I have this in my view:</p>
  
  <pre><code>&lt;? $commentWidget-&gt;options(array('allowAnonymousComment' =&gt; false));?&gt;
  &lt;? echo $commentWidget-&gt;display();?&gt;
  </code></pre>
  
  <p>Is the "Add a comment" button.</p>
  
  <p>How do I display the comments?  The plugin has views for index, edit, view...etc all seem to be laid out ok and for me to use, but... I tried a straight include, and it's missing lots of variables..etc, so - assume there's some kind of method or something to display the comments, like... <code>echo $commentWidget-&gt;comments;</code> or something?</p>
  
  <p><strong>UPDATE:</strong></p>
  
  <p>When I <code>debug($result)</code>; from <code>comment_widget.php</code>, I still just get an "Add comment" link (so there are two on the page now - one from the actual <code>-&gt;display()</code> and one from my new debug.</p>
  
  <p>Below is what I'm getting when I <code>debug($article);</code> from my articles_controller.php.
  I built the table myself, based on a few things I found online - and it appears to be populating (mostly) - maybe I did something wrong w/ the db setup?</p>
