Re: All resource reps instead of reference

Hi Arun,

BTW, the jaxb classes for the references are designed to be modified by
the users to include additional information
other than the id. For example, in your case, there should be an
EventRefConverter jaxb class. You can simply
add addition getters to serialize more information back. Think of it as
returning a preview of the actual resource.

Also, as Nam mentioned, we did talk about enhancing the code generation
to support what you suggested.
However, we are trying to figure out how to implement behaviors in the
jaxb classes to allow dynamically
changing the amount of information that gets serialized back. If you
know of any way, please let us know.

Thanks.

Peter
