RenderData()

The ColdBox Proxy also has the ability to use the request context's renderData() method. So you can build a system that just uses this functionality to transform data into multiple requests. Even have the ability for the same handler to respond to REST/SOAP and MVC all in one method:

Event Handler:

function list(event,rc,prc){
    prc.users = userService.list();
    event.renderData( data=prc.users, formats="xml,json,html" );
}

Proxy:

string function getUsers(string format="json"){
    arguments.event = "users.list";
    return process(argumentCollection=arguments);
}

This handler can now respond to HTML requests, SOAP requests, Flex/Air Requests and even RESTFul requests. How about that!
