Example:
<af:commandLink text="#{row.formattedName}" id="cl1" action="toSavePage">
 <af:setActionListener from="phoneNumber" to="#{pageFlowScope.phoneNum}"/>
 <af:setActionListener from="#{row.empId}" to="#{pageFlowScope.selectedEmployeeId}"/>
 </af:commandLink>

Show pop up from manage bean

 public static void showPopup(String clientId)
{
   FacesContext context = FacesContext.getCurrentInstance();
   StringBuilder script = new StringBuilder();
   script.append("var popup = AdfPage.PAGE.findComponent('")
            .append(clientId)
            .append("'); ")
            .append("if (!popup.isPopupVisible()) { ")
            .append("popup.show();}");
  ExtendedRenderKitService erks = Service.getService(context.getRenderKit(),

    FacesContext facesContext = FacesContext.getCurrentInstance();
    ELContext elContext = facesContext.getELContext();
    ExpressionFactory expressionFactory =
    facesContext.getApplication().getExpressionFactory();
