Yes more or less like that. But I was thinking in terms of onRender or
onComponentTagBody because I didn't know of the transformer behavior, which
looks pretty elegant. And I would also add a couple of constructors that
take one or two mappings parameters as the model to make the common case a
oneliner (I think they do that with spring mvc models). Thanks for the
example.
