title: Putting a FormPanel inside a RowExpander?
body: <p>Is there a way I can build a FormPanel <em>within</em> a RowExpander on a Grid? I'd like to create extjs forms within each row, but right now I'm limited to specifying a template which must be HTML.</p>
  
  <p>That is, I have this:</p>
  
  <pre><code>var expander = new Ext.ux.grid.RowExpander({
      enableCaching: false,
      tpl : new Ext.Template($('#row-expander-template').html())
  });
  </code></pre>
  
  <p>How do I modify this to use Ext JS Forms within the rows?</p>
