DropDown problem

Question

Hi all,
I fill a dropdown from database fields,that is working very nice.
Now, I would like to add a new line in first position in this dropdown.
I've read a few subject asking about it on the forum, but none has answered to my question, because of the JSP instructions don't seem to be the same....
Here is the interesting code of my JSP page :
<ui:dropDown binding="#{customer_search.dd1}" id="dd1"
items="#{customer_search.app_userDataProvider.options['app_user.EMPLOYEE_ID,app_user.LOGIN']}"
style="left: 600px; top: 504px; position: absolute; width: 192px" styleClass="edit-box"/> And this is the java source :
private void _init() throws Exception {
        if(getSessionBean1().getUser_seq() == 0){
                this.getExternalContext().redirect("./login.jsp");
        if(getSessionBean1().getAccess_level()!=1)
            lbl8.setVisible(false);
            dd1.setVisible(false);
        customer_listRowSet.setInt(1,getSessionBean1().getUser_seq());
        customer_listDataProvider.setCachedRowSet((javax.sql.rowset.CachedRowSet)getValue("#{customer_search.customer_listRowSet}"));
        app_userRowSet.setDataSourceName("java:comp/env/jdbc/mos_data");
        app_userRowSet.setCommand("SELECT app_user.SEQ,app_user.EMPLOYEE_ID,app_user.LOGIN FROM app_user WHERE app_user.SEQ<>? ORDER BY app_user.LOGIN");
        app_userRowSet.setInt(1,getSessionBean1().getUser_seq());
        app_userRowSet.setTableName("app_user");
        app_userDataProvider.setCachedRowSet((javax.sql.rowset.CachedRowSet)getValue("#{customer_search.app_userRowSet}"));
    private DropDown dd1 = new DropDown();
    public DropDown getDd1() {
        return dd1;
    public void setDd1(DropDown dd) {
        this.dd1 = dd;
    }Does anyone know what's the way to add a line in first position in this dropdown?
Thanks for your comments.

Using the employee table from the VIR database as an example.
Drop the employee table on the page
Add a read-only property named nameOptionsList of type com.sun.rave.web.ui.model.Option[] to the page.
Add this to the bottom of the init method.
        try {
            int listSize = employeeDataProvider.getRowCount() +1;
            log("row count " + listSize);
            this.nameOptionsList =  new Option[listSize];
            Option opt = new Option("none", "[Select One]");
            int i=0;
            nameOptionsList[i] = opt;
            employeeDataProvider.cursorFirst();         
            do {
                i++;
                String dbName =
                        (String)employeeDataProvider.getValue(
                        "EMPLOYEE.FIRSTNAME");
                log("dbName: " + dbName);
                String dbId =
                        employeeDataProvider.getValue("EMPLOYEE.ID").toString();
                opt = new Option(dbId, dbName);
                log("dbId:"+dbId);
                nameOptionsList[i] = opt;
            } while (employeeDataProvider.cursorNext());
        } catch (Exception ex) {
            throw new FacesException(ex);
