Yeah, this is an ugly situation because converters don't allow
StateHolder like Validators and Components and it's hard to initialize
them with a set of values.
Here's how I handle it. I store the stuff in a backing bean and
programmically fetch a reference to the backing bean. In your case,
the value binding would be the same one used in the page tag.
ValueBinding binding =
FacesContext.getCurrentInstance().getApplication().createValueBinding("#{backingBean.selectItemList}");
List list = (List )binding.getValue(FacesContext.getCurrentInstance());

i can't find SelectItems list in nym converter:(
here is the situation:
i have selectManyListbox thats value is binded to List<Workplcae>.
select items are binded to List<SelectItem> but each SelectItem's
value is set to one of the Workplace object.
so we have class situation that needs converter - im working on object
instead of threis IDs cause it is comfortable with hibernate stuff.
w would like to do it like this:
//========================================
public Object getAsObject(FacesContext fc, UIComponent comp, String
str) throws ConverterException {
UISelectMany selectMany = (UISelectMany) comp;
List<SelectItem> workplaces = selectMany.
getAllSelectItemsThatAreBindedToComponent(); //<<<======= problem
Integer id = new Integer(str);
for (SelectItem o : workplaces)
if (((Workplace)o.getValue()).getWorkPlaceId().
equals(id))
return o.getValue();
return null;
}
//========================================
where can i find method like this:
List<SelectItem> workplaces = selectMany.
getAllSelectItemsThatAreBindedToComponent();
cause i dont want to fetch all Workplaces from DB once again?
best regards Sławek S.
