I’m programming an OPC UA Server with your SDK, and have a problem with the events. When the Client executes the “ConditionRefresh” Method, the server provides the requested Data ( RefreshStartEvent / RefreshEndEvent) , but the “onConditionRefresh” in “MyEventManagerListener” is not fired.
The “onAcknowledge” and “onComment” works well.
I use the SampleConsoleServer (Version 4.0.2-808) as Template.
Is there something special to do, to get the “onConditionRefresh” ?
Or is there an other possibility for the server to get informed, when a Client calls the “ConditionRefresh” method.

Thanks for the report. Sounds like this could be a regression issue with the new release. We will check it and get back to it.

It is probably not possible to overcome it easily on the application level, but if we manage to fix it, we can provide you a new beta update to verify and get forward in your application. Please contact uajava-support by email about the issue, so we can provide the possible fix to you as soon as possible.

OK, we figured the problem – or details of the feature. “onConditionRefresh()” is only called for the EventManagerListener of NodeManagerRoot – not for all NodeManagers. So you will have to set a separate listener with


Not very convenient and should be considered that all listeners in all NodeManagers would be triggered.
