Html.EditorFor nullable DateTime posting back as null from view

Question

Lets make the following assumptions; ASP.NET MVC 3 Razor C#, a strongly typed view bound to a view model (not entities etc.), using the Html.EditorFor method, to edit a nullable DateTime property in the view model. The two data annotation attributes I added seem to be causing model binding to fail.

Sample view code

@model MyApp.ViewModels.NullableDateTimeViewModel

@using (Html.BeginForm())
{
    @Html.EditorFor(m => m.DateOfBirth)
}

Sample ViewModel code

[DataType(DataType.Date,
    ErrorMessage = "Please enter a valid date in the format dd MMM yyyy")]
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:dd MMM yyyy}")]
public class NullableDateTimeViewModel
{
    public DateTime? DateOfBirth { get; set; }
}

Sample controller code

[HttpPost]
public ViewResult DoB(NullableDateTimeViewModel nullableDateTimeVM)
{
    ContextDB db = new ContextDB();

    Customer cust = new Customer();

    // DateOfBirth is null so the update fails
    cust.DateOfBirth = nullableDateTimeVM.DateOfBirth.Value;

    db.Customers.Add(cust);
    db.SaveChanges();
}

The data entered in the view is not posting back to the controller when the form in the view is submitted when the data annotation attributes are added. This means that model binding is failing when using EditorFor with those attributes. Model binding works fine with TextBoxFor, the value entered in the TextBoxFor input box is passed back to the view with the view model. What is the problem here with EditorFor and the data annotation validation attributes?

Can we please find a solution that does not involved reinventing the wheel by creating multiple additional classes, helpers, templates and writing a whole lot of additional code? I am looking for a one or two line solution.
