title: renderWidget in view does nothing
body: <p>I'm trying to add a way for members to comment on articles. From what I have gathered, it should be as simple as using:</p>
  
  <pre><code>&lt;?php echo $this-&gt;content()-&gt;renderWidget('modulename.widget-name') ?&gt;
  </code></pre>
  
  <p>So this is my attempt in my view:</p>
  
  <pre><code>&lt;div&gt;
  
  &lt;?php
  echo("&lt;h2&gt;".$this-&gt;news['title']."&lt;/h2&gt;");
  
  print_r($this-&gt;news['news']);
  
  echo $this-&gt;content()-&gt;renderWidget('core.comment')
  
  ?&gt;   
  
  &lt;/div&gt;
  </code></pre>
  
  <p>I only seem to get an empty <code>&lt;div&gt;</code> tag at the bottom of my page. </p>
  
  <p>Does anyone know what I am doing wrong?</p>
  
  <p>Edit: works for <code>'core.admin-dashboard'</code> but not <code>'core.comment'</code>. Why is this?</p>
