It is not clear to me that you have 2 event classes here - is it one event
class for both objects?

ie, I would have expected to see *two* event classes in your Python code.

You can use DispatchWithEvents() on "group" here.  Eg, adding:

  group = DispatchWithEvents(group, ClassName)

would convert it into an event source.  However, as I mentioned, I would
generally expect to see 2 event classes - one for OPC, and one for group.
