title: Facebook iframe popup
body: <p>I can't get this working. I'm trying to show something <a href="http://developers.facebook.com/docs/reference/dialogs/requests/" rel="nofollow">like this</a> (see the image image from the "send to many" section). I'm getting the message "An error occurred. Please try again later."</p>
  
  <p>The code:</p>
  
  <pre><code>window.fbAsyncInit = function() {
      FB.ui({title: 'title', display: 'iframe', 
          method: 'apprequests', message: 'check this out.'
      });
  }
  </code></pre>
  
  <p>Edit1:
  The popup window shows, but inside it there's no list of friends but the above message.</p>
  
  <p>Edit2:
  And of course my app requests permissions for user's friends list on first launch.</p>
