Having troubles with Arquillian Graphene page objects

I am having troubles following the guide of Arquillian to make functional tests: http://ift.tt/1mCNCFK. Concretely at the last steps of the guide, with the Page Object abstraction.

I have all the java classes exactly like in the guide, but when i run the test it throws this exception:

org.jboss.arquillian.graphene.enricher.exception.PageObjectInitializationException: Can not instantiate Page Object class org.arquillian.example.HomePage declared in: org.arquillian.example.LoginScreenGrapheneTest

Those are my classes, xhtmls and test classes:

Java Classes:

User.java:

package org.arquillian.example;

public class User {

    private String username;

    public User() {
    }

    public User(String username) {
        this.username = username;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }
}

Credentials.java:

package org.arquillian.example;

import javax.enterprise.inject.Model;

@Model
public class Credentials {

    private String username;
    private String password;

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }
}

LoginController.java:

package org.arquillian.example;

import java.io.Serializable;

import javax.enterprise.context.SessionScoped;
import javax.enterprise.inject.Produces;
import javax.faces.application.FacesMessage;
import javax.faces.context.FacesContext;
import javax.inject.Inject;
import javax.inject.Named;


@Named
@SessionScoped
public class LoginController implements Serializable {

    private static final long serialVersionUID = 1L;

    private static final String SUCCESS_MESSAGE = "Welcome";
    private static final String FAILURE_MESSAGE = "Incorrect username and password combination";

    private User currentUser;
    private boolean renderedLoggedIn = false;

    @Inject
    private Credentials credentials;

    public String login() {
        if ("demo".equals(credentials.getUsername())
                && "demo".equals(credentials.getPassword())) {
            currentUser = new User("demo");
            FacesContext.getCurrentInstance().addMessage(null,
                    new FacesMessage(SUCCESS_MESSAGE));
            return "home.xhtml";
        }

        FacesContext.getCurrentInstance().addMessage(
                null,
                new FacesMessage(FacesMessage.SEVERITY_WARN, FAILURE_MESSAGE,
                        FAILURE_MESSAGE));
        return null;
    }

    public boolean isRenderedLoggedIn() {
        if (currentUser != null) {
            return renderedLoggedIn;
        }
        else {
            return false;
        }
    }

    public void renderLoggedIn() {
        this.renderedLoggedIn = true;
    }

    @Produces
    @Named
    public User getCurrentUser() {
        return currentUser;
    }
}

}

There is a lot of code commented in the class above, is the code pre abstract using page objects.
