Im struggling with getting this working the way i need.

I create a DocumentType called CustomerHome

This creates a CustomerHome Template

Create a new template called Customer.

Adjust the permissions on CustomerHome to allow the template Customer

Create an Umbraco node under content called Customers assigning the CustomerHome template and CustomerHome Document type.

Under this node create another page called Customer and assign the Customer template to it.

Create 2 new Controllers and Models for each page called CustomersController and CustomerController (notice the plural)

When i visit localhost:12/Customers, it loads my customers from my database which is using RenderMvcController (Can post the code if anyone likes).

When i visit localhost:12/Customers/customer the default template content is displayed.

When i visit localhost:12/Customers/customer/1 (Note the parameter 1) it throws an error

"Object reference not set to an instance of an object."

Highlighting the model is empty

My code on the Customer controller is

public class CustomerController : RenderMvcController
{

    public CustomerController()
    {

    }

    public new ActionResult Index(ContentModel model)
    {
        var vm = new CustomerContentModel(model.Content);

        return View(vm);
    }
}

I then read around and some suggest adding a route. I add a route and (this is where i think ive done something wrong)

public class RoutingComponent : IComponent
{
    public void Initialize()
    {
        RouteTable.Routes.MapRoute("customers/customer/{0}", "customers/customer/{0}", new { controller = "Customer", action = "Index", id = UrlParameter.Optional });

    }

    public void Terminate()
    {
        //throw new NotImplementedException();
    }
}

What i would like to happen is if they arrive at

localhost:12/Customers/customer the default empty template is displayed to say no customer found as no parameter has been passed in.

When i visit localhost:12/Customers/customer/1 I would like it to load up a customer from my database (which i can do) but i dont seem to be able to get past the error when passing in a customer ID?
