Your question is rather vague and broad in scope. Can you be
more specific on what you want to know, or what you are trying
to achieve?

You use causeEvent on an Object that has notifications subscribed.
So you need to consider causeEvent in relation to the notification strategy that is employed. You need to consider which objects
need to receive the notification - whether it is just a few, or
all objects in the system.

One thing to consider is whether you are using multiple schemas. Jade creates a new global object for each schema where there is only one system object. If you are running applications from multiple schemas that need to respond to the notification you might be better to use the system object.

Sorry, mean notification all users.

eg: Message say logoff for shutdown.

I will system.causeEvent so work multiple schemas.

Thanks your time.
