Невозможно переместить узел из одного дерева состояний в другое ОШИБКА с помощью Vaadin23
Я разрабатываю простое приложение на основе Vaadin 23 — Plain Java.
Для SessionManagement я создал класс с именем AppServlet.
public class AppServlet extends VaadinServlet implements SessionInitListener, SessionDestroyListener{...}
Когда я нажимаю кнопку выхода из системы, эти методы вызываются:
UI.getCurrent().getPage().setLocation("login");
VaadinSession.getCurrent().getSession().invalidate();
VaadinSession.getCurrent().close();
Вроде все работает, но при повторном входе получаю ошибку
