xmlns:rich="http://richfaces.org/rich"
template="layout/template.xhtml"
xmlns:a4j="http://richfaces.org/a4j">
<ui:define name="body">
<a4j:form>
<h:panelGrid columns="3" styleClass="gridhello" columnClasses="gridhellocolumn">
<h:outputText value="Name:" />
<h:inputText value="#{counter.strValue}" />
<a4j:commandButton value="Say Hello" reRender="out" />
</h:panelGrid>
</a4j:form>
<rich:spacer height="7"/>
<br />
<h:panelGroup id="out">
<h:outputText value="#{counter.strValue}" styleClass="outhello" />
</h:panelGroup>
<br />
</ui:define>
</ui:composition>
