ionique changement d'emplacement ne fonctionne pas

je suis nouveau dans ionique ( juste un peu moins dans angularjs ) .

je suis en train de faire un simple interrupteur entre les deux points de vue:

HTML

<body ng-app="starter" animation="slide-left-right-ios7">
    <!-- 
      The nav bar that will be updated as we navigate between views.
    -->
    <ion-nav-bar class="bar-stable nav-title-slide-ios7">
      <ion-nav-back-button class="button-icon icon  ion-ios7-arrow-back">
        Back
      </ion-nav-back-button>
    </ion-nav-bar>

    <ion-nav-view name="intro"></ion-nav-view>
    <ion-nav-view name="login"></ion-nav-view>
    <ion-nav-view name="home"></ion-nav-view>
    <ion-nav-view name="pizze"></ion-nav-view>
    <ion-nav-view name="sponsor"></ion-nav-view>
    <ion-nav-view name="scontrino"></ion-nav-view>
  </body>

APP.js

.config(function($stateProvider, $urlRouterProvider) {

  //Ionic uses AngularUI Router which uses the concept of states
  //Learn more here: https://github.com/angular-ui/ui-router
  //Set up the various states which the app can be in.
  //Each state's controller can be found in controllers.js
  $stateProvider


    .state('intro', {
      url: '/intro',
      views: {
        'intro': {
          templateUrl: 'templates/intro.html',
          controller: 'IntroCtrl'
        }
      }
    })
    .state('login', {
      url: '/login',
      views: {
        'login': {
          templateUrl: 'templates/login.html',
          controller: 'LoginCtrl'
        }
      }
    })
  $urlRouterProvider.otherwise('/intro');

});

Controllers.js

angular.module('starter.controllers', [])

.controller('IntroCtrl', function($scope,$location) {
    $location.url("/login");

})
.controller('LoginCtrl', function($scope,$location) {

})

Intro est affichée correctement, mais quand il essaie de changer de lieu de "login.html" il dit:

TypeError: Cannot read property 'querySelectorAll' of undefined

Quel pourrait être le problème???

Merci!
