Facebook App - Share link is missing while posting to user's feed

Question

I'm sharing a link on a user's feed - everything seems to be valid, but there's no Share link (Share button)... What is it that I'm doing wrong?

try {
  $su = $facebook->api(
                    "/{$uid}/feed",
                    "post",
                    array(
                      "access_token"=> $access_token,
                      "message"=> "Message",
                      "link" => "http://url",
                      "picture"=> "http://url"
                    );
} catch (FacebookApiException $e) {
  print_r($e);
}

Thanks in advance, Doori Bar
