title: Rendering show in partial
body: <p>I am getting along really well with customizing active admin, but I can't get this to work:</p>
  
  <p>In app/admin/orders.rb I have</p>
  
  <pre><code>show do
    render "show"
  end
  </code></pre>
  
  <p>In app/views/admin/orders/_show.html.erb I simply have</p>
  
  <pre><code>&lt;h3&gt;Test&lt;/h3&gt;
  &lt;% panel "General" do %&gt;
  &lt;% end %&gt;
  </code></pre>
  
  <p>Now the h3 Test is rendered just fine but the empty panel "General" gets rendered on top of the page!  </p>
  
  <p>So I get</p>
  
  <pre><code>&lt;div class="panel"&gt;
    &lt;h3&gt;General&lt;/h3&gt;
    &lt;div class="panel_contents"&gt;&lt;/div&gt;
  &lt;/div&gt;
  &lt;!DOCTYPE html&gt;&lt;html&gt;
  ...
  </code></pre>
  
  <p>Very strange...</p>
  
  <p>Thanks, I would really appreciate some help on this one!</p>
