title: In Dojo I can't get a nested ContentPane in a StackContainer to resize when new content is added to it
body: <p>I have a StackContaner which contains multiple ContentPanes.  When I try to add content to a nested ContentPane (after it has been created and rendered), it doesn't resize, it always keeps it's initially size.  Is there an easy way to get around this?  Here is how it is laid out:</p>
  
  <pre><code>StackContainer
  -ContentPane
  --ContentPane (nested)
  -ContentPane
  </code></pre>
  
  <p>Here is working example example:</p>
  
  <p><a href="http://jsfiddle.net/zzdyM/1/" rel="nofollow">http://jsfiddle.net/zzdyM/1/</a></p>
  
  <p>Click the add button in the sample, I want to make it so the divs automatically resize the height to show the new content, instead of keeping the same height with scrollbars.  Clicking the button should add another span element to the innerPane, not replace what is currently there.</p>
  
  <p>Any ideas what I'm doing wrong?</p>
