title: facebook comment box for iframe application
body: <p>I have created an iframe facebook application.  I want to use the facebook's comments functionality in this app. A user should be able to comment from my facebook applcation to facebook. It should be posted to wall also.</p>
  
  <p>I have tried to implement through fb:comment tag but the issue is that sometimes it is not rendered and when it is rendered then the comment is not posted at all (it shows the database error).</p>
  
  <p>Please tell me (any links would be helpful) how to do it and if it is possible..</p>
