Cannot get an embedded dialog to show up in facebook javascript sdk

I'm using the default stream.publish example in an iframed facebook app with the new SDK.

My problem is that the stream.publish always shows up in a popup window instead of an on page dialog. Does anyone know how to get this old behavior back?

   
 $(document).ready(function(){
     $("#streampublish").click(function() {
     FB.ui(
       {
         method: 'stream.publish',
         message: 'getting educated about Facebook Connect',
         attachment: {
           name: 'Connect',
           caption: 'The Facebook Connect JavaScript SDK',
           description: (
             'A small JavaScript library that allows you to harness ' +
             'the power of Facebook, bringing the user\'s identity, ' +
             'social graph and distribution power to your site.'
           ),
           href: 'http://github.com/facebook/connect-js'
         },
         action_links: [
           { text: 'Code', href: 'http://github.com/facebook/connect-js' }
         ],
         user_message_prompt: 'Share your thoughts about Connect'
       },
       function(response) {
         if (response && response.post_id) {
           alert('Post was published.');

           alert('Post was not published.');
         }
       }
     );
    }
    }

FB.ui({method: 'apprequests',access_token:'Valid Access Token',display:'iframe',
 message: 'You should learn more about this awesome game.', title: 'APP NAME'},
                function(response) {
                     if(response && response.request_ids){
                         alert(response.request_ids);
                     }   
                }
);

Add display:'iframe' in your code as shown above and pass a valid access token.
