Problem with declarative_authorization

Hi there,

I'm using declarative authorization and followed the steps from
Railscasts:
http://media.railscasts.com/videos/188_declarative_authorization.mov

However, when I add filter_resource_access to a controller and reload
the page then I get the error message:

Couldn't find Customer without an ID

It doesn't matter what controller I try, all controllers spit out the
same message.

Did anybody have the same problem already and can help me?

If i use filter_access_to :all I get back following error:

Illegal DSL syntax: undefined method `has_permissions_on' for
#<Authorization::Reader::AuthorizationRulesReader:0xb631b134>

My application controller looks like this:
class ApplicationController < ActionController::Base
  helper :all
  protect_from_forgery
  filter_parameter_logging :password
  helper_method :current_user
  before_filter { |c| Authorization.current_user = c.current_user }

  def current_user_session
    return @current_user_session if defined?(@current_user_session)
    @current_user_session = UserSession.find
  end

  def current_user
    return @current_user if defined?(@current_user)
    @current_user = current_user_session && current_user_session.record
  end

Here a stack trace of the error using filter_resource_access:
