Hi there,
I faced with a problem.. I am trying to add a4j:support to HtmlSelectOneListbox this way:

 private HtmlAjaxSupport addAjaxSupport(FacesContext context) throws IOException{
 HtmlAjaxSupport ajaxSupport = new HtmlAjaxSupport();
 ajaxSupport.setEvent("onclick");
 ajaxSupport.setId("ajaxSupport");

// ExpressionFactory factory = context.getApplication().getExpressionFactory();
// MethodExpression methodExpression = factory.createMethodExpression(context.getELContext(), "#{" + getListListener() + "}", null, new Class<?>[0]);
// ActionListener listener = null;

 ajaxSupport.addActionListener(getListOrgListener());
 ajaxSupport.setReRender(LIST_BOX);
 ajaxSupport.setEventsQueue(eventsQueue);
 ajaxSupport.setImmediate(true);
 return ajaxSupport;
 }

and

listBox.getFacets().put("ajaxSupport", addAjaxSupport(context));

and I am expecting that after every click on the listbox row processAction(ActionEvent event) method is invoked. I have A4J.AJAX.Submit generated indeed but it does not invoke this method. Could you tell me am I miss something?
Thanx.
