Dropdown and data provider. I want to add an item to my dropdown

Question

Hi,
here my problem. I've a downdrop. It is binded to a data provider. It works fine, all the db rows are displayed.
Now I want to add an item to my downdrop, programmatically. This because, I need to put a new selection named "ALL" into the dropdown.
This item should be the first in the dropdown list selections.
I cant' work with an option array, because it is already binded to a data provider, so how can I add an item to my dropdown programmatically?
Thank you

No problem... you're helping me!!
Well, about the data provider I just find the following code, but nothing about the "option" method. If you need I can provide you also the session bean code.
  private void _init() throws Exception {
        pers_categorieDataProvider.setCachedRowSet((javax.sql.rowset.CachedRowSet)getValue("#{SessionBean1.pers_categorieRowSet}"));
        private DropDown dropDownPersCat = new DropDown();
    public DropDown getDropDownPersCat() {
        return dropDownPersCat;
    public void setDropDownPersCat(DropDown dd) {
        this.dropDownPersCat = dd;
    private CachedRowSetDataProvider pers_categorieDataProvider = new CachedRowSetDataProvider();
    public CachedRowSetDataProvider getPers_categorieDataProvider() {
        return pers_categorieDataProvider;
    public void setPers_categorieDataProvider(CachedRowSetDataProvider crsdp) {
        this.pers_categorieDataProvider = crsdp;
    private LongConverter dropDownPersCatConverter = new LongConverter();
    public LongConverter getDropDownPersCatConverter() {
        return dropDownPersCatConverter;
    public void setDropDownPersCatConverter(LongConverter lc) {
        this.dropDownPersCatConverter = lc;
      public Indirizzario() {
      public void init() {
        // Perform initializations inherited from our superclass
        super.init();
        // Perform application initialization that must complete
        // *before* managed components are initialized
        // TODO - add your own initialiation code here
        // <editor-fold defaultstate="collapsed" desc="Managed Component Initialization">
        // Initialize automatically managed components
        // *Note* - this logic should NOT be modified
        try {
            _init();
        } catch (Exception e) {
            log("Indirizzario Initialization Failure", e);
            throw e instanceof FacesException ? (FacesException) e: new FacesException(e);
        // </editor-fold>
        // Perform application initialization that must complete
        // *after* managed components are initialized
        // TODO - add your own initialization code here
