I don't think getters and setters are needed anymore it also support
field access.

Re: wicket login problem

[Ryan Gravener]

Take a look at http://wicketstuff.org/wicket13/forminput/ and
http://cwiki.apache.org/WICKET/working-with-wicket-models.html

In your login form I would have private member variables userId and password

public class LoginForm extends Form {

private String userId;

private String password;

public LoginForm(String id) {
super(id);
setModel(new CompoundPropertyModel(this));
add(new TextField("userId"));
add(new PasswordTextField("password"));
}

public void onSubmit() {
System.out.println(userId);
}

//Make sure to add getters and setters
}

wicket login problem

[Neo Anderson]

I follow the tutorial 
http://www.developer.com/java/web/article.php/10935_3673576_1 to learn how to 
use wicket. And I want to practise not to embed the Form inside another class. 
So I create a class called LoginForm.java and move the code to there (as 
follow).
public class LoginForm extends Form {
  public LoginForm(String id) {
super(id);
  }
  @Override
  public void onSubmit() {
Object o = get("packageName.to.Login");
System.out.println("object:"+o.getClass().getSimpleName());
(Login (o)).getUserId();
(Login (o)).getPassword();
 
 }
}
However, after submit the form, I get the a NullPointerException error because 
the object o is null. How can I obtain the component of Login? Or how can I use 
the method of Login?

Thanks in advice,
