[Facebooker-talk] Session key invalid or no longer valid

[Adeel Ahmad]

This may be related to Aaron's question on Jan. 30. However in my case I
doing Facebook Connect using Facebooker for my site.
Following the Facebook Connect tutorial it does create a session and show
the user as logged in. For now I have the same 'fb' controller just to demo
log in.
However if the user logs out at facebook.com and then refreshes fb/index on
my site, I get "Session key invalid or no longer valid" on the line that
outputs @facebook_session.user.name. Just FYI if I output
@facebook_session.user.to_s it does give me the uid.
If you look at the stack trace below you'll notice that it passes through a
number of actions that test for existence and validity of the session. It
has a problem in the Error class of parser.rb. I would think it should catch
the problem a lot earlier than in parser.rb.
Any thoughts on how to troubleshoot and/or workaround this? I'm on Rails
2.1.1.
