Ruby on Rails + WebORB + authlogic + Flex

I'm developing a Rails project that uses authlogic for authentication. And I have a part in that project that is realized with Flex, and I need to know how a user can be authenticated if he or she is logged in or not.

I've set up a webservice called UserSessionService and I was trying to get the user who is logged in, but it doesn't work. If I try to get it with UserSession.find, I just get a # as the result (and therefore that's always true).

Here's the UserSessionService.rb:

require 'weborb/context'
require 'rbconfig'

class UserSessionService
  def login
    UserSession.find
  end
end

I tried to extend the UserSessionService class from Authlogic::Session::Base, but that doesn't work either.
