i need separate comment thread for each post on my website, so i followed instructions at http://developers.facebook.com/blog/post/472, ie i inserted the code:
<div id="fb-root"></div>
<script src="http://connect.facebook.net/en_US/all.js#xfbml=1"></script>
<fb:comments href="www.mysite.com" xid="postPOST_ID_HERE"></fb:comments>
under each post.
but it doesn't work and there is SAME comments thread under each post.
if i try this code:
<div id="fb-root"></div>
<script src="http://connect.facebook.net/en_US/all.js#xfbml=1"></script>
<fb:comments href="http://www.mysite.com/news.php?id=POST_ID_HERE"></fb:comments>
it seems to work, ie i get separate comment thread per post. but according to facebook instructions href parameter needs to be canonical url. am i doing something wrong in the first case or is the second example way to go (even if against facebook manual)?
