Ok. Thanks again for your input. One more clarification: Are you saying that I should always use a RESTful approach no matter what, or do you still recommend using @DataModel for some situations. BTW, By RESTful I assume you mean to inject only the object's id and look it up again on the server side. If I misunderstand the term let me know.
