 <h:graphicImage value="theme/images/ajax-loader.gif"/>
 </f:facet>
 <f:facet name="stop">
 </f:facet>
 </a4j:status>

 </div>
</h:form>

Get error According to TLD or attribute directive in tag file, attribute reRender does not accept any expressions

When

reRender="includePage:a4jPanel#{index.current}"

all id are like 'includePage:a4jPanel' (#{index.current} is empty sting)

Please help solve this problem
