Notification of transient Objects

I would like to know how "Notification: are handled for "Transient" objects and how much if any network traffic is generated by using them. I also have some specific questions.

When a notification is started for a transient class or object on a JADE client does the JADE server manage it or is it all handled by the client?

Forms and Controls are transient if you wish one control on a form to be notified when an event occurs on another control on the or on the form itself, is the notification handle completely by the JADE client or is the JADE server involved.

Thanks

Events caused by transient objects are only notified to subscribers on the node causing the event, for both system and user events. That means events caused by transient objects on a client node are managed entirely by the client node and no network traffic is involved; Only subscribers on the same node are notified. NB: If you cause an event from a server method on a transient object created by a client node the notification is *not* sent back to the client node (in current releases).

Forms and Controls are transient if you wish one control on a form to be notified when an event occurs on another control on the or on the form itself, is the notification handle completely by the JADE client or is the JADE server involved.

As mentioned above, transient notifications caused by methods executed on a client node are handled entirely within the client node, the server is not involved.
