Facebooker talk - Apr 2008 - Session Expired for Profile Publishing

Ok.  I''m not having any success with publishing profile FBML.

Example code:

class WelcomeController < ApplicationController

  layout "facebook"
  ensure_application_is_installed_by_facebook_user

  def index

    @user = facebook_session.user
    ...
    @user.profile_fbml = render_to_string( :template =>
''welcome/profile'' )

  end

end


Results in this error:

Facebooker::Session::SessionExpired (Session key invalid or no longer valid):
    /vendor/plugins/facebooker/lib/facebooker/parser.rb:386:in
`process''
    /vendor/plugins/facebooker/lib/facebooker/parser.rb:15:in `parse''
    /vendor/plugins/facebooker/lib/facebooker/service.rb:13:in `post''
    /vendor/plugins/facebooker/lib/facebooker/session.rb:399:in `post''
    /vendor/plugins/facebooker/lib/facebooker/models/user.rb:158:in
`set_profile_fbml''


Using a publisher isn''t helping.  Publisher code:

  def profile_update(user, session_user = user)
    send_as :profile
    from session_user
    recipients user
    profile render( :partial => ''profile'',:assigns => {
:profile_user => user })
  end

  ...

  MyPublisher.deliver_profile_update( @user )

Results in:

Facebooker::Session::SessionExpired (Session key invalid or no longer valid):
    /vendor/plugins/facebooker/lib/facebooker/parser.rb:386:in
`process''
    /vendor/plugins/facebooker/lib/facebooker/parser.rb:15:in `parse''
    /vendor/plugins/facebooker/lib/facebooker/service.rb:13:in `post''
    /vendor/plugins/facebooker/lib/facebooker/session.rb:399:in `post''
    /vendor/plugins/facebooker/lib/facebooker/models/user.rb:71:in
`populate''
    /vendor/plugins/facebooker/lib/facebooker/model.rb:35:in `uid''
    /app/models/publisher.rb:14:in `profile_update''
    ...

The only way I can get it to work is to start a new session and use
code as suggested in the comments here:
    <http://apps.facebook.com/facebooker_tutorial/messaging/mini_feed>

like this:

     MyPublisher.deliver_profile_update(@user.create_session.user)


That seems very wrong.  Why do I need to (1) separately store the
session_key (as in the link above) and (2) create a new session in
order to update the profile FBML?

Any thoughts?

The session expired messages normally mean that the user whose session  
you are using has uninstalled the application. Are you sure the  
session is valid?

Try calling session.user.name to make sure you can make API calls with  
that session.

The user is me!

I know I''ve got the application installed.

At the moment, I''ve resorted to creating new sessions before trying to
publish the profile FBML.  That works, but it seems excessive.

Are you using Active Record Stored sessions or the default cookie  
based ones?
I get all sorts of different session errors with cookies based  
sessions, none when using Active record storage.
