Programatic Contextual Event on Disclosure Listener - jdev 11.1.2.3

Question

Hello:
I want to programatically fire a contextual event from a DisclosureListener(when a showDetailItem is disclosed in tabbed panel). When I detect the tab is opened I want to publish the Contextual Event.
See code below
It compiles ok, but the error I get is:
oracle.jbo.uicli.binding.JUEventBinding cannot be cast to oracle.binding.ControlBinding
What am I missing here???
Thanks for the help...

Here is a small work around that might help until an ideal solution is discovered. Since the CE ActionEvent can be easily created declaratively, you can fake an producer event by programatically queuing an ActionEvent on a button binding from the disclosurelistener.
fragment code:
<ui:composition xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:af="http://xmlns.oracle.com/adf/faces/rich">
  <af:panelAccordion id="pa1">
    <af:showDetailItem text="showDetailItem 1" id="sdi1" disclosureListener="#{TesterBean.tabdisclosed}"/>
    <af:showDetailItem text="showDetailItem 2" id="sdi2"/>
  </af:panelAccordion>
  <af:commandButton text="commandButton 1" id="cb1" binding="#{TesterBean.buttonbinding}"
                    actionListener="#{bindings.eventBinding.listener.processAction}" visible="false"/>
</ui:composition>Backing Bean code:
public class TesterBean {
    private RichCommandButton buttonbinding;
    private String helloStr;
    public void tabdisclosed(DisclosureEvent disclosureEvent) {
        ActionEvent actionEvent = new ActionEvent(buttonbinding);
        actionEvent.queue();
    public String getHelloStr() {
        return helloStr; //invoked when the CE is fired
...pageDef code:
<eventBinding id="eventBinding" Listener="javax.faces.event.ActionListener">
      <events xmlns="http://xmlns.oracle.com/adfm/contextualEvent">
        <event name="buttonCE" customPayLoad="#{TesterBean.helloStr}" eventType="Action Event"/>
      </events>
    </eventBinding>
  </bindings>
  <events xmlns="http://xmlns.oracle.com/adfm/contextualEvent">
    <event name="buttonCE" customPayLoad="#{TesterBean.helloStr}" eventType="Action Event"/>
  </events>
...good luck
