I have a registration page which forwards to a confirm page, how can I get my RegistrationBean to grab the values of my outputLabels

example:-
<h: outputText value="#{reg.email}" />

@managedBean(name="reg"
...

private String email
getEmail/setEmail

I keep getting 'null', so I guess I shouldn't be using a h: outputText, but what should I be using?
The only other thing I can think to do is add a inputHidden for each param in my confirmation page:
e.g: <h:inputHidden name="email" id="email" value="#{reg.email}" />

Saying that, why has my Bean lost the values for firstname, surname etc yet it is able to display them in the JSF page?

Here is the code for viewing:-

Enter Details page:

Confirm page:

Bean:

@ManagedBean(name="reg")
@RequestScoped
public class UserRegView {

private static final long serialVersionUID = 440688044616215976L;

private FacesContextManager faceMgr = new FacesContextManager();
	private SessionManager sessionMgr = null; 
	
	@EJB UserRegService userRegService;

private String firstname;
	private String surname;
	private String email;
	private String username;
	private String password;

public UserRegView() {}

public String getFirstname() {
		return firstname;
	}
	public void setFirstname(String firstname) {
		this.firstname = firstname;
	}

public String getSurname() {
		return surname;
	}
	public void setSurname(String surname) {
		this.surname = surname;
	}

public String getEmail() {
		return email;
	}
	public void setEmail(String email) {
		this.email = email;
	}

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;
	}

public void create() throws IOException {
		Map<String, Object> map = new HashMap<String, Object>();
		map.put("firstname", this.firstname);
		map.put("surname", this.surname);
		map.put("email", this.email);
		map.put("username", this.username);
		map.put("password", this.password);
		
		boolean isCreated = userRegService.create(map);
		if (isCreated) {
			sessionMgr = new SessionManager();
			sessionMgr.setHttpSessionAuthenticatedUser();
			faceMgr.redirect("/pages/secure/myaccount.jsf");
		} else {
			faceMgr.redirect("/pages/register/enter-details.jsf");
		}
	}

public void confirm() throws IOException, ServletException {
		String username = this.username;
		boolean isUnique = userRegService.confirm(username);
		if (isUnique) {
			faceMgr.forward("/pages/register/confirm-details.jsf");
		} else {
			faceMgr.redirect("/pages/register/enter-details.jsf");
		}
	}
	
	public void signin() throws IOException {
		
	}
}

Cheers

Hi Keith,

I have't use facelets much and I don't know nothing about the FacesContextManager (class/interface ? - Do you have further infos?), but I would assume that the forward and/or redirect method of FacesContextManager can be a problem.

I had assumed that you return a String in your confirm()-method and then over the specific navigation-rule in your faces-config.xml do the forward to your result page. Why don't you use this common approach?

You 've bind your bean "reg" only on the request-scope. I'm not sure that this FacesContextManager takes care that your request-values from your input page are also available in your result page. You can also try it out to bind your managed bean at the session scope, does you still get a null value?

Best regards,
Christian
