I created suggestion box for country(nationality) using rich faces, and seam the problem am facing is "Only the topmost name in the list of the countries is displaying if also I select the country in the list of countries (like If I type "A", countries name starting with 'A' are displaying, at this time only the top most country is selected, If I select any of them).

public List autoComplete(Object suggest){
         String pref = (String)suggest;
             ArrayList result = new ArrayList();
             Iterator iterator = getAllData().iterator();
             while(iterator.hasNext()){
                 NationalityList nationality = (NationalityList)iterator.next();
                 if((nationality!=null && nationality.getCountry().toLowerCase().indexOf(pref.toLowerCase())==0)||"".equals(pref)){    
                     result.add(nationality);
                 }                
             }           
             return result;
        }
      
        public ArrayList getAllData(){
            ArrayList<NationalityList> tempList2 = new ArrayList<NationalityList>();
            tempList2 = (ArrayList<NationalityList>) getEntityManager().createQuery("from NationalityList order by id").getResultList();
            if(tempList2!=null)
            {
                for(NationalityList nationality : tempList2)
                {
                    nationalityList.add(nationality);
                }
            }
          
            return nationalityList;
        }
