FacebookMobile.logout () not working (FB has changed their mobile logout methods)

[GoogleCodeExporter]

Facebook has dramatically altered the way in which their mobile/touch 
login/logout process is handled.  This completely breaks just about everything 
the way it is currently setup in this library.  I have altered this code 
numerous times to try and stay "one step ahead of Mark" however, now I am at a 
loss.

Used to be (2 days ago) I could spawn a StageWebView window with the url:

http://m.facebook.com/logout.php and once it completed have the user logged out 
successfully.

Now the logout.php request is requiring three new variables:

http://m.facebook.com/logout.php?h=edae72809451927fdc0e5c6f3981d477&t=1307157536
&refid=7

I have no idea where these are coming from or how to get access to them.  Any 
ideas would be appreciated as this functionality (or lack thereof) pretty much 
breaks my client project I've been working on for two months.  Come on Adobe if 
you want us to use your tools you HAVE to give us better support that this.

WE'LL PAY FOR IT EVEN, JUST GIVE US SOME HELP!!!

Is your logout callback being called? Can you provide some code?

I was able to solve it by actually using this code:

        protected function logout (callback : Function = null, appOrigin : String = null, webView : StageWebView = null) : void
        {
            this.logoutCallback = callback;

            this.stageRef = stageRef;
            if (!webView)
            {
                this.webView = this.createWebView ();
            }
            else
            {
                this.webView = webView;
                this.webView.stage = this.stageRef;
            }

            this.webView.assignFocus ();
            this.webView.viewPort = new Rectangle (110, 110, this.stageRef.stageWidth - 220, this.stageRef.stageHeight - 220);

            logoutWindow = new MobileLogoutWindow (handleLogout);

            var logoutURL : String =    "https://www.facebook.com/logout.php" + 
                                        "?next=" + 
                                        "http://www.mywebsitename.com/" + 
                                        "&access_token=" + 
                                        FacebookMobile.getInstance().session.accessToken;

            trace ("logoutURL : " + logoutURL);

            logoutWindow.open (logoutURL, this.webView);

            //clears cookie for mobile.
            //          var params : Object       = {};
            //          params.confirm = 1;
            //          params.next = appOrigin;
            //          var req : FacebookRequest = new FacebookRequest ("http://m.facebook.com/logout.php");
            //
            //          openRequests[req] = handleLogout;
            //          req.call ("", params, handleRequestLoad);

            var so : SharedObject     = SharedObject.getLocal (SO_NAME);
            so.clear ();
            so.flush ();

            session = null;
        }

This is the ONLY thing that is working right now.  Although I have no idea how 
long this will work for, but I CAN tell you this... What is currently 
integrated into the lib isn't.

Please let us know if you implement a legit fix.  Thank you!

Re: the workaround above, here are you finding the class MobileLogoutWindow?  I 
don't see it in the latest source...

Oh sorry I just duped the mobile login window basically, same deal.

Tried using the above example. Having a bit of trouble getting it to work. Is 
there any other part of the code that needs to be.modified. Could we possibly 
get the source or link to the mobile log out class. Thank you for your help. :)

Here is the MobileLogoutWindow class:

Basically you will setup a listener (just as the login window has) to allow you 
to listen for a successful logout.

Would there be any chance we can a working example and the files. An FLA, AS, 
and the Facebook Classes?

This would be much appreciated. Thank you for your time.
