However, all of the methods listed on that page use the URL to transmit parameter information. Is there a class that's similar to the PageParameters class except that it hides the information it's transmitting?

问题 I'm trying to display some data using pre tag. Sometimes it won't get any data from the wicket. In that case, it should not show anything on the page. Instead, it is displaying a blank line. Please help on how to prevent the blank line from the page.

问题 (This is basically a follow on this question.) I need to access the DB service layer in one of my form validators (to make sure the email is not already taken when registering a new user). I tried the following (some input-fields omitted for brevity): public class RegistrationPage extends WebPage { @Inject private UserService userService; public RegistrationPage() { add(new FeedbackPanel("feedback")); TextField<String> email = new TextField<String>("email", Model.of("")); ... email.add(new
