      Hi,
      I have been trying to execute setActionListener method of HtmlAjaxSupport programatically. I can see that AJAX call is getting submitted to server, but somehow the method binding I have for setActionListener is not getting invoked. I am getting nuts for it. Please help me. Here is the code snippet I am using

      public void includeCheckBox(FacesContext context, int rowIndex) throws IOException {
 HtmlSelectBooleanCheckbox checkBox = new HtmlSelectBooleanCheckbox();
 checkBox.setId("checkBox_" + rowIndex);
 HtmlAjaxSupport ajaxSupport = new HtmlAjaxSupport();
 ajaxSupport.setEvent("onchange");
 ajaxSupport.setReRender(getJSFComponentId(context, "checkBox_" + rowIndex, "reportCube"));
 ajaxSupport.setActionListener(FacesContext.getCurrentInstance().getApplication().createMethodBinding("#{xmlolapReportBean.addPivotRow}", new Class[]{ActionEvent.class}));
 checkBox.getChildren().add(ajaxSupport);
 checkBox.setParent(this);
 RendererUtils.renderChild(context, checkBox);
 }


      Here are the helper methods 

      public String getJSFComponentId(FacesContext context, String id, String parentId) {
 return getJSFComponentPrefix(context, parentId) + id;
 }

 public String getJSFComponentPrefix(FacesContext context, String parentId) {
 int parentIdIndex = getClientId(context).indexOf(parentId);
 if (parentIdIndex == -1) {
 throw new RuntimeException("No parent id found for the component.");
 }
 return getClientId(context).substring(0, parentIdIndex);
 }


      And here is the bean's method I have bound to setActionListener 
      public void addPivotRow(ActionEvent event) {
 System.out.println("Hello ActionListener. I got you. Hurray!!!");
 }


      I am not able to execute this addPivotRow method when the checkBox's onchange event is called although the browser makes an Ajax request to server. I have verified it using firebug.

      Also please let me know how can I get setReRenderMethod work using this programatic approach instead of usual jsp tag approach.

      Thanks
      Ahsan
