Angular UI Router state navigation

Question

I have two state in Angular UI router:

State
|-Menus (with 2 nested state)
|   |- menus.list
|   |- menus.instruction
|-Order

When I access menus.list from menus I get the scope with id 4 however when I access menus from Order I get scope with scope id 28.

The reason this create a problem for me because I register the following function inside Menus controller.

$rootScope.$on('$stateChangeSuccess',function(event, toState, toParams, fromState, fromParams){
    if(toState.name === 'menus.list'){
        $scope.stateOrder = 1;
    }
    if(toState.name === 'menus.instruction'){
        $scope.stateOrder = 2;
    }
});

The problem I am facing is when I access menus.list from Menus it update my $scope.stateOrder in template file, but when I enter menus.list from Order state it doesn't update my $scope.stateOrder in template. Why this is happening?

I think you want to place the code with $rootScope in the run phase under the config part of your angular app, which will trigger the call back function for setting your stateOrders. for example:

angular.module('yourApp', ['ui.router'])
.config(function($stateProvider, $urlProvider) {
  //details omitted
}).run(function($rootScope, $urlRouter, $state, $stateParams) {
   $rootScope.$on('$stateChangeSuccess', function(e, toState) {
     e.preventDefault();

     if(toState.name === 'menus.list'){
        $scope.stateOrder = 1;
    }
    if(toState.name === 'menus.instruction'){
        $scope.stateOrder = 2;
    }

   })
});

When you switch between sibling states, then new controller is created and new $scope variable for Menu is created. So the easiest way to fix that is to move your $stateChangeSuccess logic to State's controller, so it's $scope going to be updated and value will be available in child controllers.
