AJAX Status#

Die Component zeit den AJAX-Status an.
<?xml version="1.0" encoding="UTF-8"?>
<html xmlns="http://www.w3.org/1999/xhtml"
	xmlns:ui="http://java.sun.com/jsf/facelets"
	xmlns:h="http://java.sun.com/jsf/html"
	xmlns:f="http://java.sun.com/jsf/core"
	xmlns:c="http://java.sun.com/jsp/jstl/core"
	xmlns:cc="http://java.sun.com/jsf/composite"
>
	<cc:interface>
		<cc:attribute name="status" default="begin"/>
	</cc:interface>
	<cc:implementation>
		<script type="text/javascript">
			jsf.ajax.addOnEvent(function(data) {
				document.getElementById('#{cc.clientId}:status').style.visibility =
					data.status == '#{cc.attrs.status}' ? 'visible' : 'hidden';
			});
		</script>
		<div id="#{cc.clientId}:status" style="visibility: hidden;">
		    <cc:insertChildren/>
		</div>
