here is my code:

Teste.java -> my backing bean



public class Teste {

 private String teste = "teste";

 public String getTeste() {
 System.out.println("buscando valor: " + teste);

 public void setTeste(String teste) {
 System.out.println("Setando valor: " + teste);
 this.teste = teste;
 }

}

 Setting this param to true should be combined with STATE_SAVING_METHOD "server" for
 best results.

 This is an EXPERIMENTAL feature. You also have to enable the detector filter/filter mapping below to get
 JavaScript detection working.</description>

 <!-- WelcomeFile Filter

 <filter-class>org.apache.myfaces.webapp.filter.WelcomeFileFilter</filter-class>
 <description>
 Due to the manner in which the JSP / servlet lifecycle
 functions, it is not currently possible to specify default
 welcome files for a web application and map them to the
 MyFacesServlet. Normally they will be mapped to the
 default servlet for the JSP container. To offset this
 shortcoming, we utilize a servlet Filter which examines
 the URI of all incoming requests.
