Expected a child component type of UISelectItem/UISelectIte
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;
}
}
