vaadin combobox addItem and option value(?)

code 

       ComboBox combo = new ComboBox('comboBox');
       combo.addItem("A");
       combo.addItem("B");
       combo.addItem("C");
       combo.addValueChangeListener(new ValueChangeListener() {

        @Override
        public void valueChange(ValueChangeEvent event) {

            com.vaadin.data.Property changedProeprty = event.getProperty();
            String value = changedProeprty.toString() ;
        }
    });

value is 'C'

However I want to input the other value, like selectBox's option in html

      <select>
         <option value="1">A</option>
         <option value="2">B</option>
         <option value="3">C</option>
       </select>

How to input the option value and how to get the option value in vaadin combobox ?

You have to set the "real" value as the items in your ComboBox. You can then use the setItemCaption(...) method to tell the system what do display in the UI.

// Set item caption for this item explicitly
select.addItem(2);
select.setItemCaption(2, "Demos");

Look in the book of vaadin for more details here
