Ok...so here is the LoginPanel class...with the constructor i was referring
to .. further the implementation for I_LoginService (i.e. LoginService...on
which the serializable error is pointing to) is being passed over from the
caller component...
public class LoginPanel extends Panel {
LoginVO loginVO = null;
public LoginPanel(String id, final String targetPage, final
I_LoginService
loginServiceHandler) {
super(id);
loginVO = new LoginVO();
setModel(new CompoundPropertyModel(loginVO));
Form loginForm = new Form("loginForm") {
protected void onSubmit() {
loginServiceHandler.authenticate(loginVO.getUserName(),
loginVO.getPassword());
}
};
loginForm.add(new RequiredTextField("userName"));
loginForm.add(new PasswordTextField("password"));
Button loginButton = new Button("loginButton") {
public void onSubmit() {
}
};
loginForm.add(loginButton);
add(loginForm);
}
