I'm using both Client-side javascript and Server-side ZK. I'd like to be able to have a client-side listener be called when a certain event is posted on the server.
Ideally, it should work like this:
Client side:
wdgt.setListener("onOK", function(evt) {alert("onOK is called.");});
Server side (in a composer):
Events.sendEvent("onOK", wdgt, "OK");
However, I haven't got this to work. Maybe I am not setting up the listener correctly? Any help is welcome.
Thanks.

Hi JJ,
Maybe you can try call widget function directly by response directly as below
<zk xmlns:w="client">
<zscript><![CDATA[
import org.zkoss.zul.Button;
import org.zkoss.zk.au.out.AuInvoke;
class CustomButton extends Button {
public void sendResponse(String key, AuInvoke auInvoke) {
response(key, auInvoke);
}
}
]]></zscript>
<label id="lb" value="label">
<attribute w:name="bind_">
function (desktop, skipper, after) {
this.$bind_(desktop, skipper, after);
this.onTestEvt = function (evtnm, msg) {
zk.log(evtnm);
zk.log(msg);
}
}
</attribute>
</label>
<button use="CustomButton"
label="call 'onTestEvt' of label">
<attribute name="onClick"><![CDATA[
self.sendResponse("label", new AuInvoke(lb, "onTestEvt", new Object[] {"onTestEvent", "message"}));
]]></attribute>
</button>
</zk>

Ben
