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?

If there is no execution, the notify will nog happen. You either need tot implementatie long operationeel for it. Check robert his small talk about long operationeel and his great solution
