    public Result index() {
        return result(OK).
                json(() -> Json.parse("{\"foo\":\"bar\"}")).
                html(() -> index.render(data().build()));
    }

@lauraluiz I think this approach is better than action composition since there are no surprises in the background/it is obvious that the endpoint supports JSON and HTML and in addition the JSON stuff or the HTML stuff will be only executed if needed.

This is only nice possible with Java 8.

Yep, it looks really nice. I'm glad that you found a way to support this nicely! :)

We have to see how Sunrise will work like, but let's have this in mind. This is not necessary if we want to reload for every change to optimize SEO, of course.
