I have a viewmodel with the following method:

@Command public void test() { Messagebox.show("Yey!!"); }

In the zul:

<div id="dataController" viewModel="com.company.DataController">...</div>

I then try to invoke the server side method as follows:

zk.Widget.$('$dataController').fire('test', null, {toServer:true})


var widget = zk.Widget.$('$dataController'); zAu.send(new zk.Event(widget, "test", {toServer:true}));

But it's not working. Any tips?

I came across @ToServerCommand and got it working but I don't really understand - has the mechanism changed from what I tried to do in my example above ?

ZK mechanism doesn't change. The reason of @ToServerCommand doesn't work is that your ViewModel binding syntax is wrong, so ZK doesn't actually create the ViewModel object.

ViewModel syntax is incorrect, it should be:

<div viewModel="@id('vm')@init('com.company.DataController')"/>

to invoke a command method, we suggest using command binding first.

If you need to invoke a command method in javascript, please check client binding API

//get a binder
var binder = zkbind.$('$dataController');
binder.command('test', null);


public class DataController{
