I liked your solution because it would allow me to use the manage-properties as managed properties of converters . However dug a little deeper into the UIComponent that is passed to getAsObject and get what I needed HtmlSelectOneMenu -> UISelectItems -> SelectItem -> the object -> the object's name . Attached is the code.

public static String getClassNameByUISelectItems(UISelectItems
uISelectItems){
List selectedItemsList ;
SelectItem selectItem ;
String className = null;
selectedItemsList = (List)uISelectItems.getValue();
for(int i = 0 ; i < selectedItemsList.size(); i++){
selectItem = (SelectItem)selectedItemsList.get(i);
if(className == null){
className =
selectItem.getValue().getClass().getName();
}else{
if(!
className.equals(selectItem.getValue().getClass().getName())){
// this means there are SelectItems
wrapping more than one type
// of object ... the dynamic converter
cannot perform magic!!
throw new ConverterException();
}
}
}
return className;
}
public static String getClassNameByUIComponent(UIComponent uIComponent){
Iterator iterator ;
Object child ;
UISelectItems uISelectItems ;
if(uIComponent instanceof HtmlSelectOneMenu){
for(iterator = uIComponent.getChildren().iterator();
iterator.hasNext();){
child = iterator.next();
if(child instanceof UISelectItems){
uISelectItems = (UISelectItems)child;
return
getClassNameByUISelectItems(uISelectItems);
}
}
}
return null;
}
public Object getAsObject(FacesContext arg0, UIComponent uIComponent,
String id)
throws ConverterException {
String shortName ;
String identifier;
MappingUtilImpl mappingUtil;
String hql ;
Object object;
String className;
className = getClassNameByUIComponent(uIComponent);
mappingUtil = (MappingUtilImpl)BackingUtil.getMappingUtil();
shortName = MappingUtilImpl.getClassNameByClassType(className);
identifier = mappingUtil.getPkPropertyByClassType(className);
hql = "FROM " + shortName + " AS a WHERE a." + identifier + " =
'" + id + "'";
try {
object = HibernateTool.get(hql);
return object;
} catch (PersistenceException e) {
e.printStackTrace();
throw new ConverterException();
}
