Why am I getting "No action responded to show" error?


I'm submitting a form to "/login". Here's my config/routes.rb file:

=======start routes.rb file===================
ActionController::Routing::Routes.draw do |map|
  map.signup '/signup', :controller => 'users', :action => 'new'
  map.login '/login', :controller => 'session', :action => 'new'
  map.logout '/logout', :controller => 'session', :action => 'destroy'

  map.resource :user

  map.resource :session

  map.connect '', :controller => "register", :action => "start"
  # The priority is based upon order of creation: first created ->
highest priority.

  # Sample of regular route:
  # map.connect 'products/:id', :controller => 'catalog', :action =>
  # Keep in mind you can assign values other than :controller
and :action

  # Sample of named route:
  # map.purchase 'products/:id/purchase', :controller =>
'catalog', :action => 'purchase'
  # This route can be invoked with purchase_url(:id => product.id)

  # You can have the root of your site routed by hooking up ''
  # -- just remember to delete public/index.html.
  # map.connect '', :controller => "welcome"

  # Allow downloading Web Service WSDL as a file with an extension
  # instead of a file named 'wsdl'
  map.connect ':controller/service.wsdl', :action => 'wsdl'

  # Install the default route as the lowest priority.
  map.connect ':controller/:action/:id.:format'
  map.connect ':controller/:action/:id'
=======================end routes.rb file==================

but I'm getting this error:

Unknown action
No action responded to show

Any ideas? Here's the relevant code from my session_controller.rb

class SessionController < ApplicationController
  # Be sure to include AuthenticationSystem in Application Controller
  include AuthenticatedSystem

  # render new.rhtml
  def new
    redirect_to :action => 'create'

  def create
    self.current_user = User.authenticate(params[:login],
    if logged_in?
      if params[:remember_me] == "1"
        cookies[:auth_token] = { :value =>
self.current_user.remember_token , :expires =>
self.current_user.remember_token_expires_at }
      # The next two lines were added 1/24/08
      @user = User.find(:first, :conditions => ["login = ?",
      session[:user_id] = @user.id
      render :controller => 'order', :action => 'start'
      flash[:notice] = "Logged in successfully"
      render :controller => 'register', :action => 'start'

Thanks for help, - Dave
