I've been looking at this at every possible angle and I can't make my mind around it, maybe you guys can help. I run this query to get my friend's hometown and location:
SELECT uid, name, timezone, hometown_location, current_location
FROM user WHERE uid IN ( SELECT uid2 FROM friend WHERE uid1 = me() )
And hometown_location and current_location are always NULL, even when they shouldn't be. Using something like /me/friends?fields=hometown,location,... has the same result.
Also, querying for my own hometown_location and current_location DOES WORK. Which makes me think I don't have the permissions to access my friends' hometown & location.. but shouldn't then an error be raised, if this was the case?
Still, my app has the same permissions: user_about_me, friends_about_me, user_hometown, friends_hometown, user_location & friends_location, so I don't think this is the issue.
If I go to http://developers.facebook.com/docs/reference/api/ and click on the https://graph.facebook.com/me/friends?access_token=... link, and I append &fields=name,hometown, it works, so I know it can be done.
Any idea what could I be doing wrong?
Thanks a lot!
