FB.getLoginStatus doesn't fire if the user is not logged in to Facebook

Question

I am working on a Facebook application which is integrated with Facebook and am trying to get the user\'s FB session. As far as I understand, a common usage scenario is as follo

Answer 1

The cause is a recent bug which only affects sandbox mode. I switched off sandbox mode, and it worked like a charm.

Answer 2

Try forcing loading the event:

FB.getLoginStatus(function(response) {
    alert('whoo hoo!!! getLoginStatus called the callback');
}, true);

It is stated in FB.getLoginStatus.

The event might be not fired in some situations.
