Converter for list within list

[rui278]

Hi. So i'm using rich:pickList, and i want to aces a list within an object wich in a list in my bean. (just to be clear bean: has list of objects asr. asr: has list of objects card)

And i want to be able to acces one of the lists within the list my source list.

Anyone know how to do that(the getAsObject method?

My current method is:     

public Object getAsObject(FacesContext arg0, UIComponent arg1, String arg2) {

     ASR5k asr = getUpperTrayBean(arg0).asrSingle;

     for (Cards card : asrSingle.getCards()){

           if (card.getSlot().equals(arg2)) {

                   return card;          

          }

      }

     return null;

}

Also, asrSingle is an instance of the object that contains the card list. It was previously selected.

By the way, the error i'm getting is:
