Hi ..
noob here with a problem ...
I have a web page with Login link on it ...
add(new Link<String>("login-page-link") {
public void onClick() {
setResponsePage(Login.class);
}
});
and this link should open Login page
Login.java
public class Login extends WebPage {
private TextField<String> userIdField;
private PasswordTextField passField;
private Form<String> form;
public final class LoginForm<T> extends Form<T> {
private static final long serialVersionUID =
-8787841681239143760L;
public LoginForm(String id) {
super(id);
}
@Override
public void onSubmit() {
String userId = Login.this.getUserId();
String password = Login.this.getPassword();
System.out.println("You entered User id "+ userId + "
and Password " +
password);
}
}
public Login(){
userIdField = new TextField<String>("user", new
Model<String>(""));
passField = new PasswordTextField("password",new
Model<String>(""));
/* Make sure that password field shows up during page re-render
**/
passField.setResetPassword(false);
form = new LoginForm<String>("loginForm");
add(form);
form.add(userIdField);
form.add(passField);
}
protected String getUserId() {
return userIdField.getModelObject();
}
protected String getPassword() {
return passField.getModelObject();
}
}
Login.html

and I get this exception:
