how to get "mutual likes" using fql in facebook?

Hi I am trying to get the likes that are shared between two friends and I am using th开发者_JAVA技巧is query:

SELECT source_id, target_id FROM connection
WHERE source_id = me()
AND source_id IN
   (SELECT uid2 FROM friend WHERE uid1 =me())
AND target_type = 'page'

which is supposed to get the pages that a user and his friends like, however I am getting an empty array in the results. What is wrong with the query?

Long time for this olution but i'm using:

SELECT object_id FROM like WHERE user_id=" + User.getCurrentUser().getFacebookId() + " AND object_id IN (SELECT object_id FROM like WHERE user_id=" + u.getFacebookId() +")";
