Work with dynamically built list of commandLinks

Question

Hi
I'm using JDeveloper 12.1.2.2.0
Description:
I have a simple page:
<af:form id="f1">
  <af:panelGroupLayout id="pgl1" layout="vertical">
    <af:forEach items="#{Bean.panel}" var="item">
      <af:commandLink text="#{item.caption}" id="cl1" actionListener="#{Bean.handlePanelAction}"/>
    </af:forEach>
  </af:panelGroupLayout>
</af:form>and a request scoped managed bean:
public class Bean {
    private List<Link> panel;
    public Bean() {
        super();
        panel = new ArrayList<Link>();
        Link link = new Link();
        link.setId(435);
        link.setCaption("Link 1");
        panel.add(link);
        link = new Link();
        link.setId(856);
        link.setCaption("Link 2");
        panel.add(link);
        link = new Link();
        link.setId(768);
        link.setCaption("Link 3");
        panel.add(link);
    public void handlePanelAction(ActionEvent actionEvent) {
        System.out.println("Hello");
    public void setPanel(List<Link> panel) {
        this.panel = panel;
    public List<Link> getPanel() {
        return panel;
}Link is a class which has two fields: id and caption.
So, the question is what is the best way to know the id of link clicked on the page? I can write id of links to the shortDest attribute of commandLink component (shortDesc="item.id"), but I think it's not a good idea.

Hi,
if you want to identify which link has clicked by user in Backing Bean
this is code
<af:panelGroupLayout id="pgl1" layout="vertical">
<af:forEach items="#{Bean.panel}" var="item">
<af:commandLink text="#{item.caption}" id="cl1" actionListener="#{Bean.handlePanelAction}">
*<f:setPropertyActionListener target="#{pageFlowScope.selectedLink}"*
*value="#{item.caption}"/>*
</af:commandLink>
</af:forEach>
</af:panelGroupLayout>
in the below line , i am just copying the caption value to pageFlowScope variable.
in the backing if you see this variable value and we can say which link user has clicked.
*<f:setPropertyActionListener target="#{pageFlowScope.selectedLink}"*
*value="#{item.caption}"/>*
BackingBean Code should be :
Object selectedLink = ADFUtils.getAdfFacesContext().getPageFlowScope().get("selectedLink");
