in java class

public class PackController extends GenericForwardComposer {

@Autowired ItemService itemService;

private Textbox txtItemCode;

@Override
public void doAfterCompose(Component comp) throws Exception {
    super.doAfterCompose(comp);


    comp.getFellow("txtItemCode").addEventListener("onChange", new EventListener() {
    @Override
    public void onEvent(Event event) throws Exception {

        int rowIndex=listboxPacking.getSelectedIndex();           
        String itemCode=readListboxOnChange(listboxPacking,String.valueOf(rowIndex));

         //find data Item
         item=new ProductItem();  
         item=itemService.getByCode(itemCode);


        //hOw to set value item.getDescription()
        //in listbox in rowActive and column 3  ?


    }});

}

public String readListboxOnChange(Listbox listboxPacking,String rowIndex){ String itemCode=null; String valueRow=null; try{ for (Object item : listboxPacking.getItems()) { if (item instanceof Listitem) { Listitem lstItem = (Listitem) item; for (Object cell : ((Listitem) lstItem).getChildren()) { if (cell instanceof Listcell) { Listcell listcell = (Listcell) cell; if (((Listcell) cell).getListheader() != null) {

                            if (((Listcell) cell).getListheader().getColumnIndex()==1) {
                                 valueRow=(((Listcell) cell).getLabel());
                             }
                             for (Object innercell : listcell.getChildren()) {
                       if (innercell instanceof Textbox ){
                                        if (((Listcell) cell).getListheader().getColumnIndex()==2) {
                                            valueItemCode=((Textbox)innercell).getValue();
                                           }
                                    }
                              } 

                      }
                  }
              }

           }

           if(valueRow.equalsIgnoreCase(rowIndex)){
              itemCode=valueItemCode.trim();
              break;
           }

       }

}catch(Exception e){
      e.printStackTrace();
}

return itemCode; }
