Requested object is not found and cannot be processed. When entering detail view of XAF NonPersistant object

Question

My Non Persistant business object is something like this

using System.ComponentModel.DataAnnotations.Schema;
[DomainComponent]
[DefaultClassOptions]
public class AcmeResult : NonPersistentObjectBase{

   [Key] public int Id { get; set; }

}

At runtime, when I open the listview and double click to enter detail view I get an error.

Answer 1

I had the wrong namespace for the key attribute. The following works.

[DevExpress.ExpressApp.Data.Key] public int Id { get; set; }
