[aadi03]

Hi All

i have a problem. I try this example and its doesn't worked, http://showcase.richfaces.org/richfaces/component-sample.jsf?demo=ajax&sample=selectsUpdates&skin=blueSky.

In this code is one valuechangelistener and it doesn't worked fine.

<ui:composition xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html"

    xmlns:f="http://java.sun.com/jsf/core" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:a4j="http://richfaces.org/a4j"

    xmlns:rich="http://richfaces.org/rich">

    <h:form>

        <h:selectOneMenu value="#{selectsBean.currentType}" valueChangeListener="#{selectsBean.valueChanged}">

            <f:selectItems value="#{selectsBean.firstList}" />

            <a4j:ajax event="valueChange" render="second" execute="@this" />

        </h:selectOneMenu>

        <a4j:outputPanel id="second" layout="block">

            <h:selectOneMenu value="#{selectsBean.currentType}" rendered="#{not empty selectsBean.currentType}">

                <f:selectItems value="#{selectsBean.secondList}" />

            </h:selectOneMenu>

        </a4j:outputPanel>

    </h:form>

</ui:composition>

can any one help me out, thanks in advanced

Hello Ganesh,

two things:

1. Are you sure that your complete facelet you are using has h:head and h:body tags where it is all nested ? Like it is done in the template for the demo in showcase here:

https://github.com/richfaces/richfaces/blob/master/examples/showcase/src/main/webapp/templates/main.xhtml

2. Are you sure that your backing bean is correct ?

Nevertheless I would like to recommend you to start with the richfaces archetypes to gain some experience. Look at developer guide how to do it:

http://www.jboss.org/richfaces/docs

hello ganesh,

you need to modify a4j:ajax event to this :

<a4j:ajax event="change" render="second" execute="@this" />

regards.
