Why don't you use a query parameter to pass a String containing a
JSON-encoded object and then use the JSONObject(String string) to parse it?
This worked like a charm!
$('#button1').click(function (event) {
$.get(specs.button1_url, {params: JSON.stringify({ a: 'b', c:
'd'}) })
.done(function(data) {
$("#responseDiv").text(data.response);
})
})
JSONObject onButton1Press(@RequestParameter("params") String jsonString) {
SimplePojo pojo = SimplePojo.build(new JSONObject(jsonString));
logger.info(pojo.toString());
return new JSONObject("response", "ok5");
}
Thank you very much Theo! If you see any further enhancements you might make
to that, I'd be very interested in hearing them.

For this kind of parameter in an event handler method, Tapestry expects it
to be in the event's activation context. I don't know of a JS
implementation of Tapestry's URLEncoder, so I prefer to use query
parameters in this case. In addition, ValueEncoder is usually (but not
obligatorily) used for mapping objects to its ids, not to a String
describing each of field values.
I thought maybe I could contribute a ValueEncoder but that only sees
individual parameters, not the whole request.
Even this might work:
JSONObject onButton1Press(JSONObject jsonObject) {
SimplePojo pojo = SimplePojo.build(jsonObject);
logger.info(pojo.toString());
return new JSONObject("response", "ok4");
}

Ajax Parameter Handling
Given a simple contrived example like this:
$('#button1').click(function (event) {
$.get(specs.button1_url, { a: 'b', c: 'd'})
.done(function(data) {
$("#responseDiv").text(data.response);
})
})
I know I can handle that in my controller in at least these two ways:
JSONObject onButton1Press() {
logger.info("a: " + request.getParameter("a") + " c: " +
request.getParameter("c"));
logger.info(request.getParameterNames().toString());
return new JSONObject("response", "ok1");
}
JSONObject onButton1Press(@RequestParameter("a") String a,
@RequestParameter("c") String c) {
logger.info("a: " + a + " c: " + c);
return new JSONObject("response", "ok2");
}
Ideally, I'd like to handle it like this:
JSONObject onButton1Press(SimplePojo pojo) {
logger.info(pojo.toString());
return new JSONObject("response", "ok3");
}
I thought maybe I could contribute a ValueEncoder but that only sees individual
parameters, not the whole request.
Even this might work:
JSONObject onButton1Press(JSONObject jsonObject) {
SimplePojo pojo = SimplePojo.build(jsonObject);
logger.info(pojo.toString());
return new JSONObject("response", "ok4");
}
But I Tapestry doesn't seem to know how to handle that. I even tried changed
the ajax params to: {params: { a: 'b', c: 'd'} }
I supposed I could build the SimplePojo from the Request, but that just doesn't
feel as clean to me.
Any suggestions would be appreciated.
Thanks
