why I can not get subnode object by using parent node created

I did the practice<a href="">Data Binding a tree UI Element</a>,and I create a customer object,in this practice I should use this object to get every node object within it,but there is no customer().nodeOrder when I press ".".Then I try to use customerNode.nodeOrder() object.The result is just one line displayed .Does anyone know it?

Probably you did not set singleton=false for the context node "Order". If you do, then every <b>element</b> of node Customer will have its own node "Order" and you can access it using

ICustomerElement customer = ...;
IOrderNode ordersOfCustomer = customer.nodeOrder();
