When I try to get all my \"likes\" (formerly fan pages) on Facebook Graph API, sometimes it returns me an empty set:
{
\"data\": [
]
Yesterday facebook fixed likes (http://developers.facebook.com/live_status#msg_612)
You can get only user likes not object likes. For example, you can not get all users by page_id.
My test user had approved my app before the likes permission had been granted so it was never picking up the likes authorisation. By removing the app from the test user's profile and authorising again I was able to get their likes.
