yes, but you must provide a way to convert those items in strings and
vice-versa... a class implementing the Converter interface.
here an example:
public class ShipperConverter implements Converter{
public Object getAsObject(FacesContext facesContext, UIComponent
uiComponent, String s) throws ConverterException {
Dao dao = new Dao();
return dao.loadObjectShipperById.(Long.decode(s));
}
public String getAsString(FacesContext facesContext, UIComponent
uiComponent, Object o) throws ConverterException {
if(o!= null)
Log.log.debug(o.toString());
try {
if((o!= null) && (o instanceof Shipper)){
Shipper shipper = (Shipper) o;
return ""+shipper.getIdShipper();
}
else
return "0";
} catch (Exception e) {
Log.log.error(e);
throw new ConverterException();
}
}
}
It is a very simplified version of the roiginal class but I think it
get the point..
hope it helps
