JS SDK FB.login() works but pop-up dialog is staying open after logged in

Question

I am using the JS SDK for Facebook based on the NEW GraphAPI for Auth/Login.

Has anyone had this issue when logging in after FB.login() was called via the JS SDK?

The problem: after I initialize by calling FB.Init() asynchronously (because this all wrapped in a window.fbAsyncInit function) the login pops up; I log in but then that pop-up refreshes to show a white page and the pop-up stays open and does not close...why? I am waiting to check response.session in the FB.login() callback but it seems as though I never get it back because this pop-up seems to just stick there and the process appears to just halt after you're logged in and I just figured this pop-up would just close and return me the response.session in the callback automatically. Why would that pop-up not go away?

I copied the url from the pop-up after I'm logged in and showing white the following url so it looks like the response is there but then why isn't that pop-up window closing so my callback can handle the response??

I did notice that when FB.login() is called and the login pop-up comes up, I see this error in FireBug talking about how it doesn't like the fact that I'm testing over localhost or something I guess:

uncaught exception: [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIDOMLocation.host]" nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: chrome://smarterwiki/content/smarterwiki.js :: anonymous :: line 1225" data: no]

that error bothers me...I need to figure out why it's coming up and I bet you I'm not the only one who has seen this when testing locally. I see no info though on troubleshooting this on the net anywhere either on the Facebook forums or elsewhere. I see others have had this issue but no resolution.

So when you implemented yours, did your facebook pop-up just close after the user is logged in or did you need to do something special to finish this process?

Also, I notice if I manually close that pop-up then go to check if that cookie was generated to contain my session, it's not (the fbs_[yourappid] cookie). So it looks like something ends prematurely here. I've got in my init cookie: true so I wonder if this problem were the pop-up dialog is not closing is related to the cookie also not being created client-side on my test PC.

I don't know what your code is, but my problem was I forget to add <div id="fb-root"></div>. My code :

<div id="fb-root"></div>
<script src="http://static.ak.fbcdn.net/connect/en_US/core.js"></script>
<script>
    FB.init({ apiKey: 'app key'});
</script>
<div class="fbloginbutton" id="fb-login" onclick="Login();">
<span id="fb_login_text" >Login with Facebook</span>
</div>
<asp:Label ID="errMsg" runat="server"></asp:Label>
<script type="text/javascript">
    function Login() {
        FB.login(function(response) {
            document.getElementById('fb_login_text').innerHTML = 'Logout';
            if (response.session) {
                FB.api('/me', function(response) {
                    var str;
                    str = response['id'] + ";" +
                            response['name'] + ";" +
                            response['first_name'] + ";" +
                            response['last_name'] + ";" +
                            response['link'] + ";" +
                            response['birthday'] + ";" +
                            response['gender'] + ";" +
                            response['email'];
                    alert(str);
                });
            }
            else {
                document.getElementById('fb_login_text').innerHTML = 'Login with Facebook';
            }
        }, { perms: 'user_birthday,email' });
    };
</script> 

As you see I don't use div fb-root anywhere but It is requered to facebook login work!
