title: Facebook app request dialog not sending request
body: <p>We have a website that uses Facebook for login. We have an invite page that displays the user's facebook friends and lets then invite them through facebook:</p>
  
  <pre><code>$('.invite_container a').live('click', function() {
      var link = $(this);
      FB.ui({method: 'apprequests',
          message: "Join me on Tailored",
          to: link.attr("user_id")
      }, function(data) {
          console.log(data);
      });
  });
  </code></pre>
  
  <p>I get the appropriate response back from Facebook, which includes the request ID and the ID's of the users who were invited. No one ever receives the invites, and when I check the request ID in the FB graph, I get returned 'false'.</p>
  
  <p>Any ideas?</p>
