Adding Rows using Complex Data Source Entity Model

Hi -

I'm using WebDataGrid to render different entity types that contain complex properties. I use ObjectDataSource to bind this entity with the WebDataGrid. A fake IList<Equipment> is provided to the source provider. Does anyone know if this is supportable or there is a trick to perform the adding of this complex entity to the datasource.

i.e.

asp:ObjectDataSource
ID="objDS"
runat="server"
SelectMethod="GetAllEntries"
InsertMethod="AppendEntry"
TypeName="WebGridDataProvider<Equipment>"
DataObjectTypeName="EntityModel.Equipment">
</asp:ObjectDataSource>

public class Equipment
{
   public EquipmentCategory Category { get; set; }
   public string Comment { get; set; }
   public bool IsCritical { get; set; }
}

When setting the manual CRUD I'm doing something like this:

_clickAddRow:

function(event, args)
{
var grid = this._DataGrid;
var entity = new Array(['123', 'InvariantName'], 'comments', 'true');
grid.get_rows().add(entity);
}

The problem occurs at the object data source when it try to convert the Category from object EquipmentCategory. Is there any sample of way to by pass this? I try to set the event Inserting, Inserted of the ObjectDataSource but those events never get fired.

Thanks for any help.
