Hello, Im simply trying to display a list of the jbpm users and their passwords, something very similar to what the login.jsp does on the jbpm webapp but I simply can't get it to work, this is what I'm doing:

private static List getUsers()
 {
 //Session session = JbpmContext.getCurrentJbpmContext().getSession();
 Session session = JbpmConfiguration.getInstance().getCurrentJbpmContext().getSession();
 IdentitySession identitySession = new IdentitySession(session);
 return identitySession.getUsers();
 }

 private static List createUsersList()
 {
 List usersList = new ArrayList();
 Iterator iter = getUsers().iterator();
 while (iter.hasNext())
 {
 User user = (User) iter.next();
 usersList.add(new Usuario(user.getName(),user.getPassword()));
 }

 return usersList;
 }

then I try to use this to fill a datatable but doesn't work

<h:dataTable value="#{loginBean.usersData}" var="user">
 <h:column>
 <h:outputText value="#{user.username}" />
 </h:column>
 </h:dataTable>

The Usuario class is a simple class with only a constructor with setters an getters

public class Usuario {

 private String username;
 private String password;

 public Usuario(String username, String password)
 {
 this.username = username;
 this.password = password;
 }
. . .
}

The jsp gives me the next error

javax.servlet.ServletException: Cannot get value for expression '#{loginBean.usersData}'

I'm new to both JSF and jBPM, so I'm really not sure where the mistake could be but I pretty much follo the UserBean class on the jBPM webapp, just adding the Usuario class to fill both username and password.
