eventBroker to a particular perspective [message #1103013]

Hi everyone,

I am doing an RCP application with 2 identical perspectives with 2 views.
I want to send an event from one view to the other.

First view :

eventBroker.send("message", model);

Second view :

@Inject @Optional
void eventReceived(@UIEventTopic("message/*") Model model) {
//CODE
}

My problem is that both perspectives receive the event.
How can i specify to send it to the activate perspective only ?

(both perspectives point to the exact same code)

Thanks for your help !
Romain.

All events are global in the sense that they're sent to every listener for the topic. Generally what you'd do is to encode the MPart you want to have react to the message in the 'payload' (we use a Map for the UIModel events so looking at UIEventPublisher might give some hints).

Alternatively you could just define different topics for each view (i.e. "messageFromA" and "messageFromB") to derermine who gets what event.
