GeneralModelChangeEventType subscription not working

[rabi-kumar]

@kevinherron Thank you for the awesome project. Currently, I am producing GeneralModelChangeEventType as per Issue676 in the node which has been very helpful.

The event can be seen in UAExpert as well

Now I am trying to understand how would the event subscription for GeneralModelChangeEventType would work. For this, I am modifying EventSubscriptionExample.java.. I am subscribing to NodeId (1, 55443) and only readvalueid has been changed, but I am getting the following error:

Upon debugging, I see that the execution stops at setEventConsumer and then returns null

Could you please help me with this?

You shouldn't change anything in EventSubscriptionExample, the Server node is still the Event Notifier, and the example is already set up to subscribe to any kind of event.

Hi @kevinherron Thank you for the suggestion. Now, what I am trying to do is I want to create another node that will act as an Event Notifier for the GeneralModelChangeEventType inside it, and change the EventSubscriptionExample which will subscribe to this single node. Do you think this is possible?

Ultimately the idea is I would browse the whole address space and would identify the event notifier node with GeneralModelChangeEvent inside it and would subscribe to these.
