[jboss-user] [JBoss Seam] - Expected a child component type of UISelectItem/UISelectIte

[burakbayramli]

Hi all, 

h:selectOneMenu is causing problems on Seam 2.0 for some unknown reason. It used to work fine on 1.2. Here is the code. 

Thanks in advance, 

          
  | <h:selectOneMenu value="#{carService.garage}">
  |      <f:selectItems value="#{carService.garages}"/>
  | </h:selectOneMenu>
  | 

  
  | @Stateful
  | @Name("carService")
  | public class CarServiceBean implements CarService, Serializable
  | {
  | ....
  | List<Garage> garages;
  |   
  |   public Map<String,Integer> getGarages() {
  |     Map<String,Integer> map = new TreeMap<String,Integer>();
  | 
  |     garages = em.createQuery("from Garage g").getResultList();
  |     
  |     for (Garage g : garages)
  |     {
  |       map.put(g.getDescription(), g.getGarageId());
  |     }
  |     return map;
  |   }
  | }
