title: Have issue with ExtJS submit form, unable to decode JSON response
body: <p>I am using an ExtJS form submit to submit form data to web server. Based on the result of the submission, I need to alert the user. I was previously sending a response of the format</p>
  
  <p>'{"success": "false", "msg": "Error creating Item. Please try again."}' </p>
  
  <p>and this worked fine using the success property for the form.submit. However, I've had to adjust the format of the response to </p>
  
  <p>'{"data":[{"success": "false", "msg": "Error creating Item. Please try again."}]}'</p>
  
  <p>as this is the JSON format required by a separate module also accessing the same result.</p>
  
  <p>Is there anyway to have the form.submit read the information correctly despite it now being wrapped in the root element?</p>
