When menu is selected event fires and page is displayed according. i.e when "sale order" is clicked page saleorder.xhtml will be renderd.

When page renderd then no event fires when value changes in h:selectOneMenu of saleorder.xhtml.... I hope i have done fine. What could be the problems....

The first question to ask in cases like this is "are there other controls on the form that have invalid values?".

When you set a listener on a control, it's not a direct pipeline to the backend code. Unless you are using AJAX, the listener won't be fired until/unless:

1. A Submit of the form is done (typically click on commandButton or commandLink).

AND

2. ALL form control data values are valid. If even one is not valid, the JSF validators will short-circuit the JSF lifecycle steps that include updating the backing bean and firing the listener.

Oh, BTW, you can get rid of those red faces by wrapping your java code and XML with "code" tags. There's a button for it on the message editor form.

thank you for many corrections.
The point is that when the content of saleorder.xhtml is

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
	xmlns:ace="http://www.icesoft.org/icefaces/components"
	xmlns:ice="http://www.icesoft.com/icefaces/component"
	xmlns:h="http://java.sun.com/jsf/html"
	xmlns:f="http://java.sun.com/jsf/core"
	xmlns:ui="http://java.sun.com/jsf/facelets">
<h:head>
	<title><ui:insert name="title">Sales Order Processing</ui:insert>
	</title>
</h:head>
<h:body>
	<f:view>
		<h:form>
			<div id="header">
				<ui:insert name="header">
					
				</ui:insert>
			</div>
			<div id="content">

<h:outputText value="Sales Order Processing" styleClass="iceOutTxt" />
				<ice:panelGrid columns="2">
					<h:outputText value="SalesMan" styleClass="iceOutTxt" />
					<h:outputText value="#{manageSaleOrder.salesmanID}" styleClass="iceOutTxt" />
					<h:outputText value="Customer" styleClass="iceOutTxt" />
					<h:outputText value="#{manageSaleOrder.customerID}" styleClass="iceOutTxt" />
					<ice:outputText value="Item" />

<ice:panelGroup>
						<ice:selectOneMenu value="#{manageSaleOrder.selectedProduct}"
							valueChangeListener="#{manageSaleOrder.listvaluechangelistener}"
							partialSubmit="true">
							<f:selectItems value="#{manageSaleOrder.listOfAvailableItem}" />
						</ice:selectOneMenu>
					</ice:panelGroup>
</ice:panelGrid>

</div>
			<div id="footer">
				<ui:insert name="footer">
					
					
					
					
					
					<h:messages></h:messages>
				</ui:insert>
			</div>
		</h:form>
	</f:view>
</h:body>
</html>

Then the

Executes fine. So form is not containing any control with invalid values.

But when the content of saleorder.xhtml is as in the original message, no event is fired.

Waiting....

It's best not to expect a quick response on the JavaRanch. Since we don't get paid, we have to do this when we aren't actually having to spend time earning a living.

Unfortunately, I haven't worked with IceFaces since they added AJAX support, so I don't know what all the options mean.
