Hi every one. let's say that i have an order system. each "Order" references a "Customer" Object. when i fill the orders list in Data Access Layer, the customer object should be brought from a Customer Web Service "WCF". so i didn't map the Customer property in the Order mapping class,

        Id(o => o.OrderID).GeneratedBy.Identity();
        //References(o => o.Customer).Not.Nullable().Column("CustomerID");
        HasMany(o => o.Details).KeyColumn("OrderID").Cascade.AllDeleteOrphan();
        Map(c => c.CustomerID).Not.Nullable();

and asked the nhibernate session to get me the orders list. and tried to loop on every order in the list to fill it's customer property, doe's any body have a good idea for this ????

 IList<Order> lst = Session.CreateCriteria<Order>().List<Order>();
 foreach (Order order in lst)
                order.Customer = serviceProxy.GetCustomerByID(order.CustomerID);
