Проблема вот в чем
@UIScope @SpringComponent @SpringUI(path = “/student_page”) @Title(“Students Page”) public class StudentPageUI extends UI { Grid grid; StudentServiceImpls studentServiceImpls; @Override protected void init(VaadinRequest vaadinRequest) { TextField filter = new TextField(); filter.setInputPrompt("Filter by last name: "); filter.addTextChangeListener(e → listStudent(e.getText())); VerticalLayout verticalLayout = new VerticalLayout(filter, grid); setContent(verticalLayout); } private void listStudent(String text) { if (StringUtils.isEmpty(text)) { grid.setContainerDataSource( new BeanItemContainer(Student.class, studentServiceImpls.getListOfStudents()) ); } }
После создания даной вюшки, идет ошибка…Что делатть?
