zk zAu.send function - org.zkoss.zk.ui.event.MouseEvent cannot be cast to org.zkoss.zk.ui.event.ForwardEvent
I am integrating jquery and zk project.
My goal is to pass value from js/jquery side to java side but in vain.
Here is the code I reference: use zAu to send data from client to server
However, there exists the error:
java.lang.ClassCastException: org.zkoss.zk.ui.event.MouseEvent cannot be cast to org.zkoss.zk.ui.event.ForwardEvent
I have seen some other person saying that we must cast the mouseevent to forwardevent in order to get a NOT NULL getData() value.
At my java side:
public class TryHttpLenovo extends SelectorComposer<Component> {
@Listen("onClick=#btnHttp")
public void serverReceive(Event e) {
ForwardEvent forwardE = (ForwardEvent) e;
System.out.println("forwardE.getData()"+forwardE.getData());
}
}
In my http.zul:
<window apply="foo.TryHttpLenovo" xmlns:w="client">
<button id="btnHttp" w:onClick="sentToServer();">http send</button>
</window>
In my testhttp.js:
function sentToServer(){
var wgt=zk.Widget.$('btnHttp');
zAu.send(new zk.Event(wgt, "serverReceive", {foo: 'my data'}, {toServer:true}));
}

After several trial-and-error, I finally solve this!!!!
The solution is to extend GenericForwardComposer.
I also adjust some other things, but the only important change is to extend GenericForwardComposer instead of SelectorComposer.
The @Listen annotation is not needed in my solution.
in .java
public class TryHttpV2 extends GenericForwardComposer {
public void onUser2$info(Event event) {
ForwardEvent forwardE = (ForwardEvent) event;
System.out.println("forwardE.getOrigin().getData(): " + forwardE.getOrigin().getData());
}
}
in .js
function sendToServer(){
payload = "using generic composer";
zAu.send(new zk.Event(zk.Widget.$(this), 'onUser2', payload));
}
in .zul
<?page title="try using generic composer" contentType="text/html;charset=UTF-8"?>
<?script src="/js/tryhttp_v2.js" ?>
<zk xmlns="http://www.zkoss.org/2005/zul">
<window id="info" apply="foo.TryHttpV2" xmlns:w="client">
<button id="btnExec" w:onClick="sendToServer();" label="to be tested button" />
</window>
