How to get the selected values from a selectmanylistbox?

Question

Hi ADF Experts,
<af:selectManyListbox label="Label 1" id="sml1" partialTriggers="cb2"
                        value="#{viewScope.TestBean.lovValue}"
                  autoSubmit="true"      valuePassThru="true">
    <f:selectItems value="#{viewScope.TestBean.actualList}" id="si1"
                   binding="#{viewScope.TestBean.selectedItems}"/>
  </af:selectManyListbox>
  <af:commandButton text="get selected values" id="cb3"
                    actionListener="#{viewScope.TestBean.getSelectedValues}"
                    partialSubmit="true"/>
  private List<String> lovValue;
  private List<SelectItem> actualList;
//getters and setters
  public void getSelectedValues(ActionEvent actionEvent) {
    // Add event code here...
    for (String selectedItem : lovValue) {
        System.out.println("Selected item: " +selectedItem.); // this is giving 1 and 3 like this. how to get the checked values as I'm getting only the indexes. In this scenario I am populating the list programmatically.Just I wanted to know how can we get the selected values(not indexes). Please suggest.
Thanks-
Abhijit
