Hi All,

Let me explain what I am tryig to do


If I include jsFunction as below in xhtml, it’s calling actionParam’s assignTo binding very well.

<h:form id="appletform">
 <a4j:jsFunction name="appletShowObject" actionListener="#{appletBean.dispatchEvent}" ajaxSingle="true" immediate="true">
 <a4j:actionparam name="param1" assignTo="#{appletBean.objectId}"/>
 </a4j:jsFunction>
 </h:form>

But, if I added the similar thing inside smApplet’s endcodeBegin() programaticaly, the actionparam’s assignTo binding never get called.
Hecne I can not pass a parameters from applet to JSF Bean.

encodeBegin()

/** Adds A4j:jsFunction to call event handlers on widget */
 private void addJSFunction(FacesContext context) {
 if(!isJSFunctionPresent()) {
 //HtmlAjaxFunction a4jFunction = new HtmlAjaxFunction();
 HtmlAjaxFunction a4jFunction = (HtmlAjaxFunction)context.getApplication().createComponent(HtmlAjaxFunction.COMPONENT_TYPE);
 a4jFunction.setName("appletShowObject");
 a4jFunction.setId(context.getViewRoot().createUniqueId());
 a4jFunction.setAjaxSingle(true);
 a4jFunction.setImmediate(true);
 Class[] params = {javax.faces.event.ActionEvent.class};
 String actionExpressionn = "#{appletBean.dispatchEvent}";
 a4jFunction.addActionListener(new MethodExpressionActionListener(
 FacesUtils.createMethodExpression(actionExpressionn, null,
 params)));
 addA4jParams(context, a4jFunction, "param1", "#{appletBean.objectId}",String.class);

 this.getChildren().add(a4jFunction);
 }
 }

private void addA4jParams(FacesContext context, HtmlAjaxFunction a4jFunction,String paramName, String Expression,Class<?> expectedType) {
 HtmlActionParameter a4jParam = (HtmlActionParameter)context.getApplication().createComponent(HtmlActionParameter.COMPONENT_TYPE);
 a4jParam.setName(paramName);
 a4jParam.setId(context.getViewRoot().createUniqueId());
 ValueExpression valExpr = context.getApplication()
 .getExpressionFactory()
 .createValueExpression(context.getELContext(),Expression,expectedType);

 //a4jParam.setAssignToBinding(valExpr);
 a4jParam.setValueExpression("assignToBinding", valExpr);
 Class[] params = {javax.faces.event.ActionEvent.class};
 String actionExpressionn = "#{appletBean.setParamValue}";
 a4jParam.setActionListener(
 FacesUtils.createMethodExpression(actionExpressionn, null,
 params));

 a4jFunction.getChildren().add(a4jParam);
 }

Your any help is highly appreciated.

Thanks in Advance!!!!!
