what does <!-- ngView : undefined --> mean - angularjs

Question

I get a dom like this:
<div class="row">
<::before>
<div class="col-lg-12">
<!-- ngView: undefined -->
<ng-view class="ng-scope">
<h1 class="ng-scope">Hello world</h1>
</ng-view>
</div>
<::after>
</div>
What does:
<!-- ngView: undefined -->
mean?
Everything seems to work fine, but I don't like this comment as it seems that something is not working properly?
The template look like this:
<h1>Hello world</h1>
and it is configured like this :
var myApp = angular.module('myApp', [
'ngRoute',
.....
]);
myApp.config(['$routeProvider', function($routeProvider){
$routeProvider.when('/my_template', {templateUrl: '/web-angular/my_template.html'})
.when( ..... );
}]);

Answer 1

Place your 'ng-view' directive in a div or span. Such as ...
<div ng-view></div>
<span ng-view></span>
Check out the IE restrictions here AngularJS IE Guide and take a look at number 3 and 4. From this, I take it that this is simply a warning. Something to catch your attention, and mine, just as it did. Note that declaring ng-view in your class will still work, but you will get the same warning message in your markup.

Answer 2

For anyone else coming across this and not having any luck with the other answer, I had this problem because I hadn't included the controller as a dependency of the module.
angular.module('myApp', ['module-for-missing-page'])
Including this dependency got the view loading correctly.

inject ur view in an anchor tag.Like this
<div>
Home
Students
Courses
<ng-view> </ng-view>
</div>
var app = angular.module("MyApp", ["ngRoute"])
.config(function ($routeProvider) {
$routeProvider
.when("/home", {
templateUrl: "Templates/home.html",
controller: "homeController"
})
.when("/courses", {
templateUrl: "Templates/courses.html",
controller: "courseController"
})
.when("/students", {
templateUrl: "Templates/students.html",
controller: "studentsController"
})
})
.controller("homeController", function ($scope) {
$scope.message = "I am in home controller";
})
.controller("courseController",function($scope){
$scope.message = "I am in courses controller";
})
.controller("studentsController", function ($scope) {
$scope.message = "I am in students controller";
})
and check whether u have put the correct ng-route links or not.
