Hi Tim,

There seems to be some stuff missing, have you stepped through this in the debugger?

You are registering the details as a child and calling a method to retrieve the order header, but not the details. Plus you have set the entity object directly. I would have thought to see something like this:

oOrder = (Order)this.registerBizObj(new Order());
oDetails = (OrderDetails)this.registerBizObj(new OrderDetails());
oOrder.RegisterChildBizObj(this.oDetails);

// This will retrieve the order header
oOrder.GetOrderByOrderID(10251);
// This will retrieve the detail items.
oDetails.GetDetailsByOrderID(this.oOrder.Entity.OrderID);

// Then when you delete the first line all you have done is removed it from the list.
// You could call an actual delete method
