JSON in Tapestry
Hi, I'm new to tapestry, now I want to create a page which could handle ajax
request and return JSON response. But I can't get it work. Here is what I
did:
First I have a page which extends BasePage and implement IJSONRender:
public abstract class JsonPage extends BasePage implements IJSONRender {
public void renderComponent(IJSONWriter writer, IRequestCycle cycle) {
System.out.println("RenderJSON!!");
writer.array().put("some data");
}
}
Then I have Home.page:
<page-specification class=".....JsonPage">
</page-specification>
Then I have Home.html:
<html jwcid="@Shell" title="Test">
<body jwcid="@Body">
<script>
dojo.require("tapestry.event");
dojo.event.connect(tapestry, "loadJson", function(type, data, http,
kwArgs){
alert("load json!");
alert("data:" + data);
for (var e in data) {
alert(e + ":" + data[e]);
}
});
tapestry.bind("http://127.0.0.1:8080/war/app", {}, true);
</script>
</body>
</html>
The client side will show a message box said "load json!", but the json data
that client retrieved is always an empty object. Also, the server console
does not print "RenderJSON!!", which means that the renderComponent of my
TestPage was never called. I don't know what to do. Could somebody help me
out? Thank you very much!!

I'm not sure if IJSONRender will work with pages, but i know it works with
components.
The trick is then to generate a url that will rerender that component... similar
to a directlink url that defines the updateComponents parameter accordingly
