Vaadin eventBut duplicate event

Flow
1

I using EventBus in my app, but sometimes the event are duplicated,

I have one view with one

@Autowired 
private EventBus.UIEventBus eventBus;

in this view I subs:

eventBus.subscribe(this);

Then when I click in one button I open another component, I use this code:

public static void abrirJanela( String titulo, Integer altura, Integer largura, Component tela, Window.CloseListener closeListener, boolean icCloseable){
        Window window = new Window(titulo);
        window.setCaption(titulo);
        window.setWidth(largura, Sizeable.Unit.PERCENTAGE);
        window.setHeight(altura, Sizeable.Unit.PERCENTAGE);
        window.setModal(true);
        window.setClosable(icCloseable);
        if(closeListener != null){
            window.addCloseListener(closeListener);
        }
        Class<?> clazz = tela.getClass();
        Field field;
        try {
            field = clazz.getDeclaredField("window");
            field.setAccessible(true);
            field.set(tela, window);

        } catch (Exception e) {
            logger.log(Level.WARNING,"View sem uma propriedade com o nome window");
        }
        window.setContent(tela);
        UI.getCurrent().addWindow(window);
        try{
            Method foco = clazz.getMethod("focus");
            foco.invoke(tela);
        } catch (NoSuchMethodException e) {

        } catch (InvocationTargetException e) {

        } catch (IllegalAccessException e) {

        }
    }

and this is my comp:

@SpringComponent
@UIScope
public class QualificarApresentanteImpl extends QualificarApresentante{

    private Apresentante apresentante = new Apresentante();
    private Window window;

    @Autowired
    private EventBus.UIEventBus eventBusApresentante;

    public QualificarApresentanteImpl() {
        btnSalvarApresentante.addClickListener(evt -> fecharJanela());
        txtDocumento.addShortcutListener(new ShortcutListener("Shortcut Name", ShortcutAction.KeyCode.ENTER, null) {
            @Override
            public void handleAction(Object sender, Object target) {
                fecharJanela();
            }
        });
        txtApresentante.addShortcutListener(new ShortcutListener("Shortcut Name", ShortcutAction.KeyCode.ENTER, null) {
            @Override
            public void handleAction(Object sender, Object target) {
                fecharJanela();
            }
        });
    }

    private void fecharJanela() {
        CPFValidator cpfValidator =new CPFValidator();
        try {
            cpfValidator.assertValid(txtDocumento.getValue());
            this.window.close();
//            this.eventBusApresentante.publish(this, new CartorioInteligenteEvent.FinalizarMovimentacao());
        }catch (InvalidStateException v){
            Notification.show("Número de CPF Inválido", Notification.Type.ERROR_MESSAGE);
        }

    }
    
    public void focus(){
        txtApresentante.focus();
    }

    public String getNomeApresentante(){
        return txtApresentante.getValue();
    }
    public String getNrDocumentoApresentante(){
        return this.txtDocumento.getValue();
    }
    public Apresentante getApresentante(){
        apresentante.setNome(txtApresentante.getValue());
        return apresentante;
    }

    public void setNome(String nmApresentante){
        this.txtApresentante.setValue(nmApresentante);
    }
    public void setNrDocumentoApresentante(String documento){
        this.txtDocumento.setValue(documento);
    }


    public boolean isPreenchido() {
        boolean retorno = true;
        if(Strings.isNullOrEmpty(txtApresentante.getValue())){
            retorno = false;
        }
        if(Strings.isNullOrEmpty(txtDocumento.getValue())){
            retorno = false;
        }
        return retorno;
    }
}

and this is the method that receive the event

@EventBusListenerMethod(scope = EventScope.UI)
private void finalizarMovimentacaoListener(CartorioInteligenteEvent.FinalizarMovimentacao finalizarMovimentacao){
   finalizarPedidoClickEvent();
}

so sometimes that method are execute 2 times. anyone know why?

tks

I think this is normal. If you debug the details of the event, you will notice that certain “events” are actually series of events.
