ChoiceProvider
At the very least each choice should contain an id attribute. If no custom rendering function is
specified, the text attribute should also be provided
Example: If mapping a User {Long id, String name} using default rendering the code should look like this:
toJson(User choice, JSONWriter writer) {
writer.key("id").value(choice.getId()).key("text").value(choice.getName());
}
