Order not returning custom values

[sashwill]

OrderIf order = kkAppEng.getOrderMgr().getCheckoutOrder();
            System.out.println(order.toString());
            OrderProductIf[] op = order.getOrderProducts();
            for (OrderProductIf a : op) {
                System.out.println("custom1 =" + a.getCustom1());
                System.out.println("custom2 =" + a.getCustom2());
                System.out.println("custom3 =" + a.getCustom3());
                System.out.println("custom4 =" + a.getCustom4());
                System.out.println("custom5 =" + a.getCustom5());
              }

Looking at the above code, the order.toString() prints all the custom values for the order but not for the product and I've verified that the orders table in the database contains the values.  However all println prints all the custom values as null while other things such as name and price and quantity are correct.  Can someone tell me why?
