title: Facebook Request Dialog API: Request or Invitation
body: <p>Facebook Requests Dialog seem to generate two kinds of notification messages </p>
  
  <ol>
  <li>Janet sent you requests in CityVille.</li>
  <li>Janet have invited you to CityVille.</li>
  </ol>
  
  <p>How does one specify which one to use. I couldn't find any options in </p>
  
  <pre><code>FB.ui({method: 'apprequests', message: ''});
  </code></pre>
  
  <p>By default it seems to be generating message of type 1. App permission doesn't seem to effect this.</p>
  
  <p>The legacy fb:request-form <a href="http://developers.facebook.com/docs/reference/fbml/request-form" rel="nofollow">http://developers.facebook.com/docs/reference/fbml/request-form</a>  had options - 'invite' and 'type' to do exactly that. </p>
  
  <p>How does one do the same thing using the Facebook Request Dialogs today ?</p>
