problems with extended permissions

[Paco Garat]

Hi, first sorry for my english, i am developing a facebook app with symfony framework, and i have a problem with the scope parameter. I get the access_token with this code:

$appId=$this->container->getParameter('oauth.facebook.appId');

$secret=$this->container->getParameter('oauth.facebook.secret');

$code=$this->getRequest()->get('code');

$scope='read_mailbox';

$token_url = "https://graph.facebook.com/oauth/access_token?"

. "client_id=" . $appId."&redirect_uri=" .urlencode("https://87.218.201.45/login/facebook"). "&scope=".$scope 

."&client_secret=" . $secret . "&code=" . $code;

$url = $token_url;

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, "$url");

curl_setopt($ch, CURLOPT_HEADER, 0);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);

curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);

$result = curl_exec($ch);

echo $result;

$params = null;

parse_str($result, $params);

$token=$params['access_token'];

curl_close($ch);

return $token;

but when the enhanced oauth dialog appears doesn't show the extended permission and when i execute this query:

$this->fql('SELECT+message_id+FROM+message+WHERE+message_id+>+0', $token, false);

i've got this error:

{"error":{"message":"An access token is required to request this resource.","type":"OAuthException","code":104}}

I don't have problems accessing public information.

Thanks for helping me,
