how to make custom error feedback messages in SignInPanel in Wicket - passwords

Question

I am implementing a LoginPage with Wicket, and I am not getting it, how to write the custom Feedback messages, for ex, "Password is wrong", "Username is wrong" or "Accound is locked out" (the last example should be a bit more difficult because it is related to Ldap/Ldap error messages I think.. But I think there is an easier way for the second two, with the properties file of my LoginPage or something like that.. I tried to change the default Wicket "login failed" message, and this through the properties' file of my page, I just added "signFailed=Sign in failed TEST", and it got changed.. but didn't got it how to tell the user why! Pass or username is wrong!
here the implementation:
public class LoginPage extends SampleManagementPage {
private static final long serialVersionUID = -8585718500226951823L;
private SignInPanel signIn;
public LoginPage() {
signIn = new SignInPanel("signInPanel");
add(signIn);
}
}
and my SampleManagementPage extends WebPage!
here the properties' file of LoginPage:
page.title=Login for Sample Management
signInFailed=Sign in failed TEST

The reason why you are able to change only the signFailed error message, is that wicket SignInPanel throws only this particular error in case it's sign-in form fails to authenticate. To see that, you can open the source code of SignInPanel.java.
One way to overcome the problem and produce your own error messages, is write your own sign-in panel. I m not saying it is the only way but it worked for me :)
public class LoginPanel extends Panel {
private static final long serialVersionUID = -1662154893824849377L;
private static final String SIGN_IN_FORM = "signInForm";
private boolean includeRememberMe = true;
private boolean rememberMe = true;
private String password;
private String username;
public LoginPanel(final String id, final boolean includeRememberMe) {
super(id);
this.includeRememberMe = includeRememberMe;
add(new FeedbackPanel("feedback"));
add(new SignInForm(SIGN_IN_FORM));
}
#Override
protected void onConfigure() {
if (isSignedIn() == false) {
IAuthenticationStrategy authenticationStrategy = getApplication().getSecuritySettings().getAuthenticationStrategy();
String[] data = authenticationStrategy.load();
if ((data != null) && (data.length > 1)) {
if (signIn(data[0], data[1])) {
username = data[0];
password = data[1];
onSignInRemembered();
} else {
authenticationStrategy.remove();
}
}
}
super.onConfigure();
}
private boolean signIn(String username, String password) {
return AuthenticatedWebSession.get().signIn(username, password);
}
private boolean userExists(String username) {
return ((MyWebSession) AuthenticatedWebSession.get()).userExists(username);
}
private boolean isSignedIn() {
return AuthenticatedWebSession.get().isSignedIn();
}
protected void onSignInFailed() {
error(getLocalizer().getString("signInFailed", this, "Wrong password"));
}
private void onUserExistsFailed() {
error(getLocalizer().getString("userExistsFailed", this, "User does not exist"));
}
protected void onSignInSucceeded() {
continueToOriginalDestination();
setResponsePage(getApplication().getHomePage());
}
protected void onSignInRemembered() {
continueToOriginalDestination();
throw new RestartResponseException(getApplication().getHomePage());
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public LoginPanel(final String id) {
this(id, true);
}
public final class SignInForm extends StatelessForm<LoginPanel> {
private static final long serialVersionUID = 1L;
public SignInForm(final String id) {
super(id);
setModel(new CompoundPropertyModel<LoginPanel>(LoginPanel.this));
add(new TextField<String>("username"));
add(new PasswordTextField("password"));
WebMarkupContainer rememberMeRow = new WebMarkupContainer("rememberMeRow");
add(rememberMeRow);
rememberMeRow.add(new CheckBox("rememberMe"));
rememberMeRow.setVisible(includeRememberMe);
}
#Override
public final void onSubmit() {
IAuthenticationStrategy strategy = getApplication().getSecuritySettings().getAuthenticationStrategy();
if (!userExists(username)) {
onUserExistsFailed();
strategy.remove();
return;
}
if (signIn(getUsername(), getPassword())) {
if (rememberMe == true) {
strategy.save(username, password);
} else {
strategy.remove();
}
onSignInSucceeded();
} else {
onSignInFailed();
strategy.remove();
}
}
}
}
public class MyWebSession extends AuthenticatedWebSession {
private static final long serialVersionUID = -401924496527311251L;
public MyWebSession(Request request) {
super(request);
}
public boolean userExists(String username) {
// business login
}
#Override
public boolean authenticate(String username, String password) {
// business login
}
#Override
public Roles getRoles() {
Roles roles = new Roles();
roles.add(Roles.USER);
return roles;
