script events
I have c# code in a DLL that is connecting to the Genesys cloud platform. How do I set up custom events in my Pega script so that I can respond to events occurring in my c# code?
public Class
{
public delegate void OnNotificationHandler();
public event OnNotificationHandler OnNotification;
}
public Constructor()
{
[API].OnNotification += Event1;
[API].OnSubscribed += Event2;
[API].OnUnSubscribed += Event3;
[API].OnNotificationStarted += Event4;
[API].OnDisconnect += Event5;
}
public void Event1()
{
OnNotification?.Invoke();
}

@ScottC37 You might have to tweak things, but I did get this script working mostly. It seems to fire the event multiple times, but I believe that is because I am not unsubscribing from it afterwards. You'd need to instantiate your object from Genesys inside your script. You'd also need to be running the script in order for the event to be caught as far as I know.

Do I need to add the method 'add_MyEvent' to the automation and if so, what do I connect to the value parameter?

@ScottC37 In my automation, I called the TriggerEvent method. When I called that, the event was triggered in the script and it was responded to by the OnMyEvent handler.

@ScottC37Are you instantiating the component from the DLL inside your script? I believe it would at least need to have done that to be able to subscribe to the events.

I decided to bypass the script in Pega and call the API directly from the automation. I've created the proxy of the class in the DLL, however, I am getting several errors when I add the events.
Exception from the log file:

@ScottC37 Without access to the DLL, I can't really speculate. I suspect the first error is really a result of the second one. The missing link error would happen if any object had changed since it was opened in the automation surface. It may just be a case of a missing reference or something like that. You might open a support request to see if they can assist as this might need some hands-on to resolve.
