Componente autocomplete

A veces no queremos que nuestro código sea muy extenso y usamos componentes

se pasa el converter como parámetro
se pasa el metodo complete
se indican los labeltip1 hasta labeltip6

En la pagina list.xhtml

  <p:outputLabel value="#{msg['field.idrol']}"/>
   <e:autocompleterol listener="#{rolController.handleAutocompleteOfListXhtml}"
                       value="#{rolController.rolSelected}"
                       itemLabel="#{p.idrol}"
                       field="idrol"
                       converter="#{rolConverter}"
                       completeMethod="#{rolController.rolServices.complete}"
                       labeltip1="#{msg['field.idrol']} #{p.idrol}"
                       labeltip2="#{msg['field.rol']} #{p.rol}"
                       update=":form:dataTable"/>

En una pagina new.xthml / view.xhtml de un formulario Usuario

Múltiple
o Simple

  <e:autocompleterol listener="#{usuarioController.handleSelect}"
                      value="#{usuarioController.rolList}"
                      itemLabel="#{p.rol}"
                      dropdown="true"
                      multiple="true"
                      required="true"
                      minQueryLength="0"
                      field="idrol"                                                                                                                                                      
                      converter="#{rolConverter}"
                      completeMethod="#{rolController.rolServices.complete}"
                      labeltip1="#{msg['field.idrol']} #{p.idrol}"
                      labeltip2="#{msg['field.rol']} #{p.rol}"   
    />

Controller

Inyectar el services

  @Inject
    RolServices rolServices;

Método para invocar desde los list.xtml para busquedas

handleAutocompleteOfListXhtml(SelectEvent event)

   public void handleAutocompleteOfListXhtml(SelectEvent event) {
        try {
         rolList.removeAll(rolList);

            lookupServices.setIdrol(rolSelected.getIdrol());
            loginController.put("searchro", "idrol");

        } catch (Exception e) {
            errorServices.errorMessage(nameOfClass(),nameOfMethod(), e.getLocalizedMessage());
        }
    }// </editor-fold>

handleSelect para invocar desde los new.xhtml y view.xhtml

  public void handleSelect(SelectEvent event) {
        try {


        } catch (Exception e) {
            errorServices.errorMessage(nameOfClass(),nameOfMethod(), e.getLocalizedMessage());

Componente

Para invocar el método handleSelect, definimos method-signature "void handleSelect(org.primefaces.event.SelectEvent)"
