Basic usage of ILink to go to next page. This is a listener method.
public ILink doNextPage() {
return getPageService().getLink(false, "pages/TheSecondPage");
}
Example of ILink in a real life situation - logging in. This is a
listener on the Log In button.
@Bean
public abstract ValidationDelegate getValidationDelegate();
public ILink doLogin() {
ILink redirectTo = null;
try {
// If errors already detected by validators, return
without redirect
if (getValidationDelegate().getHasErrors()) {
return null;
}
// Authenticate the user, password
// ...insert code...
// Redirect to WelcomePage
redirectTo = getPageService().getLink(false,
"pages/WelcomePage");
return redirectTo;
}
catch (MyAuthenticationException e) {
recordError(e.toString());
}
catch (Exception e) {
// This should never happen, but we've caught it just
in case
// (and should probably log it instead of just printing
stack trace)
e.printStackTrace();
// Display general error, retrieving message from
application's .properties file
recordError(getMessages().getMessage("login_problem"));
}
return redirectTo;
}
protected void recordError(String message) {
ValidationDelegate delegate = getValidationDelegate();
delegate.setFormComponent(null);
delegate.record(message, null);
}
