[jboss-user] [JBoss Seam] - Simple example using selectOneListbox without CRUD?

I've been trying for quite a few hours now to get selectOneListBox to work, and I'm not having much luck. I've reviewed the posts and the ui example in the Seam 2 distribution as well. What I'm doing is fairly straight forward, passing a list to selectOneListBox, and trying to use the value selected in a method in a SFSB. It's worth noting that while the code I've included doesn't use s:selectItems, I've tried that as well, with the same error being thrown.
This is part of my SFSB class
| @Stateful
| @Name("createAction")
| public class CreateAction implements Create{
|
| @PersistenceContext(type = EXTENDED)
| EntityManager em;
|
| @Logger
| Log log;
|
| @Out(required = false)
| List<SelectItem> clients;
|
| @In(required = false)
| private Object selectedClient;
|
| public String createSelectClient(){
| List<ClientPerson> clientList = em.createQuery("Select c from ClientPerson c").getResultList();
| clients = new ArrayList<SelectItem>();
| for(ClientPerson clientPerson : clientList){
| clients.add(new SelectItem(clientPerson.getName()));
| }
| return "selectClient";
| }
|
| @Remove @Destroy
| public void destory(){}
| }
|
and this is from my .xhtml page where the list is shown:
| <h:selectOneListbox id="pickClient" value="#{selectedClient}" styleClass="clientSelectBox">
| <f:selectItems value="#{clients}" var="client" />
| </h:selectOneListbox>
|
I'm rather confused as to what the error is actually pointing out. When I used s:selectItems and my converter, I saw that after clicking my commandButton, the object was being retrieved from
| public Object getAsObject(FacesContext context, UIComponent component, String value)
|
The error is:

Does anyone have a simple example that uses a SFSB or SLSB with selectOneListbox and not CRUD?
Does anyone know what could be causing this error?
Thanks
