title: Facebook 3.0 : Session.newPermissionsRequest callback not get called
body: <p>I was using the openForRead to ask for the read permissions and after the callback I set for the openForRead I made another publish stream request using newPermissionsRequest and assigned it with a new callback to it. But the new callback didn't get called. </p>
  
  <p>Does anyone know why is that? It does ask me the publish permission but when i clicked ok, the callback didn't get called.</p>
