Tab with onEnter to change state throw error

ionic-v1
1

Hi all. Sorry for a newbie question but I have tried to google but cannot find a solution. I am trying to use ‘onEnter’ to check if the user has login, and then change to state to login page. The state has been changed correctly and it enter my login page. However, it throw some strange error on firebug. Here is my code:

    .state('tabs.account', {
      url   : '/tabs/account',
      views : {
        'tab-account'  : {
          templateUrl : 'templates/account.html',
          controller  : 'accountCtrl'
        }
      },
      onEnter : function($state, $localStorage) {
        var user = $localStorage.get('user');
        if (user == null || !user.logged)
        {
          $state.go('member');
        }
      }
    })

state for ‘member’:

    .state('member', {
      url         : '/member',
      templateUrl : 'templates/member.html',
      controller  : 'memberCtrl'
    })

and what I get from firebug:

try to put this into your controller: $scope.$on( "$ionicView.enter", function() { // do whatever });

it should be something like that. But I cannost test it right now
