Hi Dennis, Thanks for your answer. I am not sure I understand your suggestion about treating the id values as strings. Where would those strings be stored in the unmarshalled object? Are you suggesting to add a customerId property of type string to the account class, and specify a pre-get method that fills in the customerId just before marshalling?
