why my website display in FB Login window After Login through facebook?

I am Integrating Face book application with Our Website. My Website is in Java's [Google Web Toolkit] Framework 2.0.1

When we press FB-connect connect then FB's Login window comes, after that user enters email & pwd.

When user clicks FB's connect button then Our website display in that Login window.

Authentication and Connect Url is Proper http://localho开发者_如何转开发st:8090/websitename/

How to solve this problem ?

Where I did mistake ?

Is there any solution?

When I did same thing in GWT's development/Hosted mode with Authentication and Connect url http:/127.0.0.1:8888/ then works properly. Then why It create Probelm in localhost? :-/

On some browsers, localhost is not allowed to save cookies.

Try to deploy the app to see if the problem goes away.

I create new application, and provide My website url in Everywhere i.e
authentication : Post-Authorize Callback URL / Post-Remove Callback URL
Canvas : Canvas Callback URL
Connect : Connect URL / Account Preview URL.

And my problem is solved Now :) !!!
