I Create one project. but when 2 clients try to access the same view, I got connector erro
Cannot remove from parent when the session is not locked
How annotation I need to put to fix? I try to put UIScope but dont work
Can you post some code?
Sure.
My UI:
@SpringUI
@Theme("caixa")
@Widgetset("br.com.lumera.caixa.CaixaWidgetset")
public class CaixaUI extends UI{
private Navigator navigator;
@Autowired
private SpringViewProvider viewProvider;
@Override
protected void init(VaadinRequest request) {
VerticalLayout layout = new VerticalLayout();
Panel viewContent = new Panel();
viewContent.setSizeFull();
MenuBar menuBar = new MenuBar();
MenuItem itemCaixa = menuBar.addItem("",FontAwesome.BARS, null);
itemCaixa.addItem("Dashboard Caixa", FontAwesome.AREA_CHART, event -> navegar(DashboardCaixaView.VIEW_NAME));
itemCaixa.addItem("Relatório FCRCPN", FontAwesome.AREA_CHART, event -> navegar(RelatorioFCRView.VIEW_NAME));
itemCaixa.addItem("Dashboard Receitas", FontAwesome.AREA_CHART, event -> navegar(DashboardReceitaView.VIEW_NAME));
layout.addComponents(menuBar,viewContent);
layout.setSizeFull();
layout.setExpandRatio(viewContent, 1);
navigator = new Navigator(this, viewContent);
navigator.addProvider(viewProvider);
setContent(layout);
navigator.navigateTo(DashboardCaixaView.VIEW_NAME);
}
private void navegar(String viewName) {
navigator.navigateTo(viewName);
}
}this is my View

The error occurs when the method private void mostrarDadosMovimentacao(Object obj){ are executed
You can remove @Push annotation from the View; the annotation is meant to annotate UI classes.
Then add @ViewScope annotation to DetalheMovimentacaoView so it is view scoped and every view will have its own instance, otherwise ther will be a a sinlge application-wide instance.
Make me know if this will fix your problem

Dont works marco.
Hi Fabio,
where is the metod mostrarDadosMovimentacao invoked in your code?
Can you also post the exception stacktrace?
here
private void mostrarDadosMovimentacao(Object obj){
MovimentacaoDashboard movimentacao = (MovimentacaoDashboard) obj;
try{
Window window = new Window(null);
window.setModal(true);
window.setSizeFull();
window.setResizable(false);
MovimentacaoDashboard retorno = financeiroService.getDadosMovimentacao(movimentacao.getCodigo());
detalheMovimentacaoView.setarDados(retorno);
window.setWidth(80, Unit.PERCENTAGE);
window.setContent(detalheMovimentacaoView);
UI.getCurrent().addWindow(window);
}catch(Exception e){
Utils.showNotification(e.getMessage(), Type.ERROR_MESSAGE, UI.getCurrent().getPage());
}
}and i have
@Autowired
DetalheMovimentacaoView detalheMovimentacaoViewbut I try to replate to
DetalheMovimentacaoView detalheMovimentacaoView = new DetalheMovimentacaoView(); inside my method and still the same error
That’s weird. Could you post the stack trace please?
Another question. Is the method mostrarDadosMovimentacao invoked from a background thread?
I’m asking because I noticed you tried to add @Push annotation
Sorry man… works.
the @ViewScope works…
I was testing on wrong port 
and getting the old version
It’s monday effect, don’t worry 
Glad I could help
Cheers
Marco
