Description

I have an client app that was created and had been working, it makes a call to one webservice.
The webservice was upgraded, it added some new methods and it also added a new property (Type) to one of the return types I was using.
Now my app will no longer work, i get a runtime error, java.lang.RuntimeException: Unexpected subelement Type, when the results are returned to my service.
If i rebuilt the client stub code using wsdl2java with the new wsdl my app will work again.

As I understand it, adding fields to a object should not break any existing code. Any Xml elements returned that are not known elements should be ignored and not cause exceptions in the client code.
I have tested my assumption with Visual Studio 2005, if i genereate web service client code using the old wsdl I can still call the new service without an exception being thrown because of the new Xml element being returned.

Is there some option that I don't know of that will allow for new elements to be returned without exceptions being throw?
