Just a suggestion, pass the UserDto to the service layer and let the
service layer do the conversion. Then you can look at <a href="
http://code.google.com/p/simple-object-assembler/";>Simple Object
Assembler</a> to encapsulate the conversion. Hint: use
automapWhenNoConverterFound property and you won't need to write any
converters for Simple Object Assembler (assuming your properties follow a
naming convention).

Subject: Re: Using Wicket with businness model classes that check
for rules
Thanks James I'll investigate on extending PropertyModel.
Currently I'm doing the following:
public class UserRegistrationPage extends WebPage {
@SpringBean
private UserService userService;
private FeedbackPanel feedbackPanel;
private UserDto userDto; // only has the User properties
@SuppressWarnings("unchecked")
public UserRegistrationPage() {
feedbackPanel = new
FeedbackPanel("feedback");
userDto = new UserDto();
CompoundPropertyModel userDtoModel = new
CompoundPropertyModel(userDto);
// bind to the DTO
Form registrarForm = new
Form("registerForm", userDtoModel){
@Override
protected void onSubmit()
{
try {
// Create a real User and obtain
the
data from the DTO
User user = new User(userDto.getEmail(),
userDto.getName(),
userDto.getPassword(),
userDto.getBirth());
userService.save(user); // service calls the dao which actually saves
to DB
} catch
(Exception e) { // The Businness Exception has the message error
feedbackPanel.warn(e.getMessage());
}
}
};
registerForm.add(new
TextField("email").setRequired(true)); // form binded
to the DTO properties
...
