If I remove the rich:select component, the form renders without a problem..

[peter.falken]

Are using a Bean Method to populate your rich:selectItems?

Do you have a bean.xml in the WEB-INF of your WAR?

[pcoll]

Im using a @Stateless Bean

@Stateless

@ManagedBean(name = "crearSolicitud")

public class Solicitud {

    private String fecha;

    private Integer municipio;

    private Integer parroquia;

    @NotEmpty(message = "Debe Ingresar su nombre")

    private String solicitante;

    @NotEmpty(message = "Debe Ingresar el nombre de su organizacion")

    private String organziacion;

    @NotEmpty(message = "Debe Ingresar la direccion del donde se genera el problema")

    private String direccion;

    @Email(message = "Verifique su correo")

    @NotEmpty(message = "Debe Ingresar su correo")

    private String email;

    @NotEmpty(message = "Debe Ingresar la descripcion del problema")

    private String reporte;

    my list for the rich:select component

    private List<Municipio> listadoMunicipios;

    public Solicitud() {}

    @PostConstruct

    public void init() {

        MunicipioParroquia listaMuni=new MunicipioParroquia();

        this.listadoMunicipios=listaMuni.listadoMunicipios();

    }

     getters and setters   

}

This is where I get de list

public List<Municipio> listadoMunicipios() {

        SessionFactory sf = HibernateUtil.getSessionFactory();

        Session session = sf.openSession();

        session.beginTransaction();

        List<Municipio> municipios = session.createQuery("from Municipio").list();

        session.close();

        return municipios;

     }

Im declaring a Bean through annotations... I dont have a bean.xml in the WEB-INF folder..Looking through some tutorials, they dont mention any bean.xml file..

[pcoll]

I've tried somethig else, when I changed the rich:select component from loading data from a DB to this

                         <rich:select id="select" defaultLabel="Select Value..."

                                value="#{crearSolicitud.var}">

                                <f:selectItem itemValue="0" itemLabel="Banana" />

                                <f:selectItem itemValue="1" itemLabel="Cranberry" />

                                <f:selectItem itemValue="2" itemLabel="Blueberry" />

                                <f:selectItem itemValue="3" itemLabel="Orange" />

                                <f:selectItem itemValue="4" itemLabel="Strawberry" />

                                <f:selectItem itemValue="4" itemLabel="Apple" />

                            </rich:select>

I still get the error... even when Im not populating the rich:selectItems component..

[pcoll]

Apparently JSF stores the page component structure in HttpSession and If the page content is very large and the session has not been previously created, some response may have been written and the error above happens..

so the solution is to create the session before the Facelet (/JSF) page is printed.

An crude example could be like:

@PostConstruct
void initialiseSession() {
    FacesContext.getCurrentInstance().getExternalContext().getSession(true);
}

creating the session before, preventes this error to happen Cannot create a session after the response has been committed
