Facebook like not working for Unauthorized Users

I ma implementing a facebook like function for my site using FBML.If click like as facebook authorized its working fine .But Whenever i clic开发者_C百科k as unauthorized it pops up for the login and successfully logs in.But it doesnt perform the like operation. I have to click it again to like it.I would appreciate any help.

I have a feeling that you manually reload a page after log in. It should automatically call like after you login in an authorization popup.
