Hi

I have a simple controller which also acts as a JMX Notification Listener. Whenever I get a JMX notification I see the message on the first line of handleNotification(...) logged but setX("whatever") does nothing.

public class MyController implements NotificationListener
{ 
   private String x;

   public void setX(String x) { 
       this.x = x;
   }

   public String getX() {
       return x;
   }

   @Override
   public void handleNotification(Notification n, Object handback)
   {
       LOG.info("handleNotification called");
       setX(n.getMessage()); // supposed to update text on button, but does not.
       // trying to post notifychange event manually
       BindUtils.postNotifyChange(null,null,this,"x");
   }
}

In my zul file I have simply:

<div viewModel="@id('vm') @init('com.foo.MyController')">
    <button label="@load(vm.x)"/>
</div>

So what can be the problem? I think handleNotification might be called on another thread and that's why notifychange does not work?
