I have developed a small example, showing how events could be sent synchronously or asynchronously to multiple or all reactive receivers inside of an application.

An additional package (to be added to an existing model) contains two classes - a Publisher Singleton and as Subscriber Baseclass - and a stereotype in order to make any reactive class a subscriber to that service.

See the uploaded zipped model for Rhapsody v7.1 (and above?)

Hi Luke,

thanks for your example. I've just found this forum and think this example migth be usefule for me. However, since I'm using Rhapsody v7.0 I could not yet open it. What's more, I would need a solution for RiC (not RiC++).

So without having seen the actual model, I would have following question: does this class just broadcast the specified events to all subscribers simultanously? And can therefore all receivers handle the events?

Because what I would be looking for is a mechanism to broadcast events to multiple receivers...but only exactly one receiver is allowed to handle it (according to some specified priority).

As an example: a Keyboard class distributes its events (e.g. keyDown, keyUp) to a class MainMenu and a second class SMSEditor - if the higher priority class (here SMSEditor) cannot handle the event, only then the lower priority one (MainMenu) shall try to handle it.

But from the description of your example I think this is out of scope of your solution!? If so, do you have an idea on how to implement such a mechanism in RiC?
