[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
