Re: Acitivities and places:problem in using eventBus

Ah, sorry, no idea (except you should use com.google.web.bindery.event.shared.Event instead of com.google.gwt.event.shared.GwtEvent, but that shouldn't change anything to your problem)

thank you for the reply here is the code

Hi everyBody,

I want to transfer an object from an activity to another one, for that i used the event bus:

1. i created an event "AddSoumissionEvent"  and handler "AddSoumissionHandler"
2.intialise the eventbus of the first activity with the eventBus offered in the start Function

 

 public void start(AcceptsOneWidget containerWidget, EventBus eventBus) {
         
        this.eventBus=eventBus;
                .......

}

 

3.i  fire event in the first activity

public void createSoumission(DynamicForm form) {
 
        //create soumission

            Soumission soumission=new Soumission();

         
           //initialize values
        ................
         //fire event

            eventBus.fireEvent(new AddSoumissionEvent(soumission));
       
    }

4. the second activity receive the event ,i created the handler in in start funtion

public void start(AcceptsOneWidget container, EventBus eventBus) {


eventBus.addHandler(AddSoumissionEvent.TYPE, new AddSoumissionHandler(){

              public void onAddSoumissionHandler(AddSoumissionEvent event) {
                  System.out.println(" event received youpiiii");
                  onAddSoum();
                   
              }
             
             
          });

}

the problem is the second activity doesn't receive the event :( i can't see where is the mistake .

can anyone here tell me where is the mistake or give me a link for an example who shows how to use the eventBus with activities and places

Thank you,
