Access to Components in backing constructor

Question

Hi friends,
i want execute code for change the state of components with the next methods:
private UIComponent getComponent(String nombre) {
return getComponent(fc.getViewRoot(), nombre);
private UIComponent getComponent(UIComponent componente, String nombre) {
Iterator<UIComponent> items = componente.getFacetsAndChildren();
while (items.hasNext()) {
UIComponent item = (UIComponent)items.next();
UIComponent found = getComponent(item, nombre);
if (found != null) {
return found;
if (item.getId().equalsIgnoreCase(nombre)) {
return item;
return null;
but in the backing constructor:
the fc.getViewRoot() is only component and nothing more , like to null,
i find any component and result is null.
But... i execute again or refresh page , then i find component correctly, why is this ?????
any ideas??
i need disable any component programmatic bye code java at charge page first time.

in the backing the code is :

}the class super base.java

            System.out.println("resultados:" + com);
            if (com == null) {
                System.out.println("Primer dato nulo");
            if (com instanceof RichCommandButton) {
                RichCommandButton boton = (RichCommandButton)com;
                boton.setDisabled(true);
        } catch (Exception ex) {
            System.out.println("error:" + ex.getMessage());
    private UIComponent getComponent(String nombre) {
        return getComponent(fc.getViewRoot(), nombre);
    private UIComponent getComponent(UIComponent componente, String nombre) {

            if (found != null) {
                return found;
            if (item.getId().equalsIgnoreCase(nombre)) {
                return item;
        return null;
}the result of execute the first time :
ejecutando clase base:Mon Jun 14 11:38:34 BOT 2010
constructor base
Pagina Resultado:/pagina1.jspx
Buscando el componente:cb1
resultados:null
Primer dato nulo
then a press a any button , and the result of contructor is this:
ejecutando clase base:Mon Jun 14 11:39:15 BOT 2010
constructor base
Pagina Resultado:/pagina1.jspx
Buscando el componente:cb1
resultados:RichCommandButton[UIXFacesBeanImpl, id=cb1]
why is this??
