title: Help on Facebook Graph API, returns "false" but UID is public
body: <p>I really could not understand why on some Facebook objects (being more specific: user posts) the Graph API returns false when using an access_token obtained via OAuth by an application, but NOT by using a user access_token.</p>
  
  <p>I have an example here:
  <a href="https://graph.facebook.com/10150158049595775?access_token=XXXXXXXXXX" rel="nofollow">https://graph.facebook.com/10150158049595775?access_token=XXXXXXXXXX</a></p>
  
  <p>This post is public, and I have no friends in common with this user.</p>
  
  <p>If you try to access the url above by using a token obtained via the usual Facebook OAuth scheme, the server return "false".</p>
  
  <p>If you use your user access token, for example the one that FB gives you by visiting the examples in this page <a href="http://developers.facebook.com/docs/reference/api/" rel="nofollow">http://developers.facebook.com/docs/reference/api/</a>, the Graph API correctly gives you the users's post detail.</p>
  
  <p>I believe it's not a matter of extended permissions required, first because the post above is public, and second, because for testing I've tried to make my application generate a token by asking ALL user permissions (yes, all permissions found on developers.facebook.com/docs/authentication/permissions/) and the answer was always "false".</p>
