Does the DataAnnotations.DisplayAttribute.Order property not work with ASP.NET MVC 2?

I set values for the Order property of the Display attribute in my model metadata.

[MetadataType(typeof(OccasionMetadata))]
public partial class Occasion
{
    private class OccasionMetadata
    {
        [ScaffoldColumn(false)]
        public object Id { get; set; }

        [Required]
        [Display(Name = "Title", Order = 0)]
        public object Designation { get; set; }

        [Required]
        [DataType(DataType.MultilineText)]
        [Display(Order = 3)]
        public object Summary { get; set; }

        [Required]
        [DataType(DataType.DateTime)]
        [Display(Order = 1)]
        public object Start { get; set; }

        [Required]
        [DataType(DataType.DateTime)]
        [Display(Order = 2)]
        public object Finish { get; set; }
    }
}

I present my models in strongly-typed views using the DisplayForModel and EditorForModel methods.

<%= Html.DisplayForModel() %>

and

<%= Html.EditorForModel() %>

But, ASP.NET MVC 2 displays the fields out of order! What might I have wrong?

Brad Wilson said November 2009:

There is no support for order in MVC 2, and it's not likely to be there until MVC 3. One major reason is that DataAnnotations in .NET 4 have added ordering support, but since we rely on 3.5, we cannot do it yet.

.NET 4 DataAnnotations comes with a new Display attribute that has several properties including specifying the value that is used for display in the UI and a ResourceType. Unfortunately, this attribute is new and is not supported in MVC 2 RTM.

The good news is it will be supported and is currently available in the MVC Futures release.

The steps to get this working are shown below...
