Using the Twitter.Bootstrap.MVC4 is it possible to pass "null" to the **Customer controller** in the ExampleLayoursRoute.config:

```
public static void RegisterRoutes(RouteCollection routes)
    {
        routes.MapNavigationRoute<HomeController>("Home Page", c => c.Index());

        routes.MapNavigationRoute<CustomerController>("Customer", null)  <-- pass null here
              .AddChildRoute<CustomerController>("List", c => c.Index())
              .AddChildRoute<CustomerController>("Add", c => c.Create())
            ;
    }

```

I get an error: Object reference not set to an instance of an object in the NavigationRouteconfigureationExtensions.cs file:

```
  public static NamedRoute ToDefaultAction<T>(this NamedRoute route, Expression<Func<T, ActionResult>> action,string areaName) where T : IController
    {
        var body = action.Body as MethodCallExpression; <--- Error here

```

You can't add a link to the same controller/action:

```
        routes.MapNavigationRoute<CustomerController>("Customer", c => c.Index())
              .AddChildRoute<CustomerController>("List", c => c.Index())

```

Or you get the error: {"A route named 'Navigation-Customer-Index' is already in the route collection. Route names must be unique.\r\nParameter name: name"}

My only workaround so far, is to add a second duplicate Action in the controller, and name it Index2 (for example):

```
public ActionResult Index()
    {
        return View(db.Customers.Where(x => x.UserName == User.Identity.Name).ToList());
    }

 public ActionResult Index2()
    {
        return View(db.Customers.Where(x => x.UserName == User.Identity.Name).ToList());
    }

```

Is there a better way, than duplicating code, or adding unnecessary actions?
