Hi,

I am using an evaluation copy of OPC UA JAVA Client SDK to subscribe to OPC UA Server Events. I’m using your sample code provided in the client tutorial document (as below). However, I’m getting multiple event notification (sometimes 2, sometimes 3) for a single server side Alarm/Event raised. So, please let me know if I’m doing anything wrong or provide me the fix for it. Thanks.

MonitoredEventItem eventItem = new MonitoredEventItem(nodeId, filter);
eventItem.addEventListener(eventListener);
subscription.addItem(eventItem)

//The event listener is defined as follows, and used to react to the event notification:
protected final MonitoredEventItemListener eventListener = new MyMonitoredEventItemListener(this,
eventFieldNames);;

Regards,
Sachin
