I did it few months back.. I left it in between cause i need to implement cascading in alfresco share. but I managed it working in alfreco explorer as well. here is the code i have implemted. See it if this help….

          this.list=list;
       }

          return new Object();
       }

                      return item.getLabel();
                   }
                }
          }
          else if(value instanceof List) {

             for(String val : (List<String>)value) {
                for(SelectItem item : list) {
                    if (item.getValue().equals(val)) {
                       result += item.getLabel() + " ";
                       break;

                 }
             }
             return result;

          return new String();
