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]
        [DisplayName("Title")]
        [Display(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?
