var routerApp = angular.module("routerApp", ["ui.router"]);



routerApp.config(
  ["$stateProvider", "$urlRouterProvider",
    function($stateProvider, $urlRouterProvider) {

      $urlRouterProvider.otherwise("/template1");

      $stateProvider
        .state("template1", {
          url: "/template1",
          templateUrl: "template1.html",
          controller: "tmp1Controller"
        })
        .state("template2", {
          url: "/template2",
          templateUrl: "template2.html",
          controller: "tmp2Controller"
        })



      ;

    }
  ]);

routerApp.controller("mainCtrl", ["$scope",

I had the same problem, was solved replacing

<div ui-view></div>

by

<ui-view> 
 <i>Loading ....</i>
</ui-view>
