title: extjs - How to submit a form when the response is not json?
body: <p>I understand that when I submit a form, according to <a href="http://docs.sencha.com/extjs/4.2.2/#!/api/Ext.form.Basic-method-submit" rel="nofollow">the documentation</a> ExtJs by default parses the response as JSON.</p>
  
  <p>In my case, the server returns HTML, that I want to display in a Panel. When I submit the from using <code>getForm().submit()</code>, ExtJs will throw an error about invalid JSON:</p>
  
  <pre><code>Ext.JSON.decode(): You're trying to decode an invalid JSON String
  </code></pre>
  
  <p>How can I tell ExtJs not to attempt to parse the response ? I could the access the text with the <a href="http://docs.sencha.com/extjs/4.2.2/#!/api/Ext.form.action.Action-property-response" rel="nofollow">response object</a>.</p>
