[Facebooker-talk] facebook_session not working for me

Tue Apr 29 10:41:22 EDT 2008

When user B clicks to install the application, they should be  
redirected to a page asking them to install the application. That's  
what the "ensure_application_is_installed_by_facebook_user" does. Is  
User B not asked to install the application?
