This code

    listData.setItemRenderer(new ListitemRenderer<Course>(){

        @Override
        public void render(final Listitem item,final Course data,final int index)
                throws Exception {
            // TODO Auto-generated method stub

            Listcell seq = new Listcell((index+1)+"");
            item.appendChild(seq);

            Listcell code = new Listcell(data.getId());
            item.appendChild(code);



                grade = new Combobox();
                grade.appendItem("A");
                grade.appendItem("B");
                grade.appendItem("C");
                grade.appendItem("D");
                grade.appendItem("F");


            Listcell gradeS = new Listcell();
            gradeS.appendChild(grade);
            item.appendChild(gradeS);

            selectGrade.addEventListener(Events.ON_SELECT, new EventListener<Event>(){

                @Override

                    selectGrade.getModel();
                    //ListModelList lists = (ListModelList)selectGrade.getModel();
                    String g = selectGrade.getValue();


                    System.out.println(g);
