Why not pass your javascript an event link? Then your js can invoke getJSON, tapestry will handle the request and call an event handler server-side. Your event handler can then store the value and return a JSONObject. You can stick the value into the url as a request parameter and get it back out by injecting the Request object into your page/component/mixin. Better yet, if you're using T5.2.4, you can map the request parameter directly to an event handler via the @RequestParameter annotation.
