Part of my xhmtl-Page:

<rich:autocomplete autocompleteMethod="#{autocompletMit.searchbyName()}" mode="cachedAjax" 
                           fetchValue="#{controller.mitarbeiter.mitarbeiterName}" autocompleteList="#{autocompletMit.autocompleteList}" minChars="1" autofill="true" var="it" > 
    <h:outputText value="#{it.mitarbeiterName}" style="font-weight:bold"/>  
    </rich:autocomplete>

Bean for my Autocomplete:

@ManagedBean(name = "autocompletMit")
@RequestScoped
public class AutoCompleteMitarbeiter implements Serializable {

    @EJB
    private Transaktionssteuerung transakt;
    private List<String> autocompleteList = new ArrayList<String>();
    String nameSearch;

    public List<String> searchbyName(Object o) {
        String test = (String) o;  //always get here a NullPointerException
        List<Mitarbeiter> alleMitarbeiter = transakt.alleMitarbeiter();
        for (Iterator<Mitarbeiter> it = alleMitarbeiter.iterator(); it.hasNext();) {
            if (it.next().getMitarbeiterName().startsWith(test)) {
                autocompleteList.add(it.next().getMitarbeiterName());
            }
        }
        return autocompleteList;
    }

I always get a NullPointerException for String test = (String) o; I dont know how to get the StringInput correctly from </rich:autocomplete>-Input....
