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,
