The example of Spring Boot's Chapter6 maybe has a problem

The method updateList() needs a parameter,the code like this:
private void configureFilter(){ filterText.setPlaceholder("Filter by name..."); filterText.setClearButtonVisible(true); filterText.setValueChangeMode(ValueChangeMode.LAZY); filterText.addValueChangeListener(e -> updateList(e.getValue())); } private void updateList(String value) { grid.setItems(contactService.findAll(value)); }
