Here is the code:

private DropDownChoice<SelectedTrackProfileVO> savedReportsDropDown;

savedReportsDropDown = new
DropDownChoice<SelectedTrackProfileVO>("profileDropDown",savedReportsDropDownList);
 
savedReportsDropDown.setChoiceRenderer(new
ChoiceRenderer<SelectedTrackProfileVO>("reportName", "cstmReportId")); 
savedReportsDropDown.setOutputMarkupId(true); 
savedReportsDropDown.setOutputMarkupPlaceholderTag(true); 
savedReportsDropDown.add(new AjaxFormComponentUpdatingBehavior("onchange"){ 

    
    private static final long serialVersionUID = 1L;
