Hi,

How do we receive server events?
The client sample shows how to subscribe to data change but not how to subscribe to server event.
Here is my current code but it s not working yet.
Maybe I should not subscribe to the root folder but the server object, but I understood that we should receive events from sub-nodes.
Thank you
Olivier

private static MonitoredEventItemListener eventListener = new MonitoredEventItemListener() {
@Override
public void onEvent(MonitoredEventItem sender, Variant[] eventFields) {
println(eventToString(sender.getNodeId(), eventFields));
}
};

//EventFilter filter = new EventFilter();
subscription = new Subscription();
//MonitoredEventItem eventItem = new MonitoredEventItem(Identifiers.RootFolder, filter);
MonitoredEventItem eventItem = new MonitoredEventItem(Identifiers.RootFolder);
eventItem.addEventListener(eventListener);
subscription.addItem(eventItem);
subscription.setPublishingEnabled(true);

Yes, you cannot monitor the RootFolder. If you want all events, you should monitor Server object. Or you can monitor a node that has HasEventSource or HasNotifier references to nodes under it. The events are triggered based on these references from the lower levels.
