You shouldn't have a code like this:
getRequestCycle().setRedirect(false);
getRequestCycle().setRequestTarget(EmptyRequestTarget.getInstance());
getResponse().redirect("
https://mysite/app/?wicket:bookmarkablePage=:com.myapp.UserAccount";);
A more 'wicket way' of doing thins is this:
setResponsePage(UserAccount.class);
That means that a bookmarkable page will be created (a new instance of the
page will be instantiated).
You can also do something like this:
setResponsePage(new UserAccount(account));
Or you could try to make this page as stateless as possible by passing
account id or other parameters to the page.... that depends..
