problem with ActionController.add_renderer :txt and respond_with

rubyonrails-core

the code..

Mime::Type.register "text/plain", :txt

ActionController.add_renderer :txt do |object, options|   self.content_type ||= Mime::TXT   self.response_body = object.inspect end

class Goal < ActiveRecord::Base   def to_s     name   end end

class GoalsController < ApplicationController   respond_to :html, :xml, :json, :yaml, :txt

  # GET /goals   # GET /goals.xml   def index     @goals = Goal.all     respond_with @goals   end

  # GET /goals/1   # GET /goals/1.xml   def show     @goal = Goal.find(params[:id])     respond_with @goal   end

class GoalsController < ApplicationController   respond_to :html, :xml, :json, :yaml, :txt

  def index     @goals = Goal.all     respond_with @goals   end

  def show     @goal = Goal.find(params[:id])     respond_with @goal   end

  ... end

results in.. Template is missing

Missing template goals/show with {:formats=>[:txt], :handlers=>[:rjs, :rhtml, :rxml, :erb, :builder], :locale=>[:en, :en]} in view paths "/home/rob/machine/app/views", "/home/rob/machine/vendor/ plugins/min_max_attribute/app/views", "/home/rob/machine/vendor/ plugins/map_attribute/app/views", "/home/rob/machine/vendor/plugins/ lib_ifit/app/views", "/home/rob/machine/vendor/plugins/dynamic_form/ app/views", "/home/rob/machine/vendor/plugins/attribute_bitmask/app/ views", "/home/rob/machine/vendor/plugins/acts_as_nested_set/app/ views", "/var/lib/gems/1.8/gems/devise-1.1.2/app/views"

so, how do I get this to work? the :yaml example works...
