What I was trying to achieve was a generic sortable header for dataTable. Here's the template:
header.xhtml <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" | "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd";> | <ui:composition 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:column> | <f:facet name="header"> | <h:commandLink action="#{bean.sort(columnName)}"> | <h:outputText value="#{columnLabel}" /> | <h:outputText value="#{sortAscending ? ' ASC' : ' DESC'}" | rendered="#{sortColumn == columnName}" /> | </h:commandLink> | </f:facet> | <ui:insert /> | </h:column> | </ui:composition> | This template is declared in Facelet taglib as: <?xml version="1.0"?> | <!DOCTYPE facelet-taglib PUBLIC | "-//Sun Microsystems, Inc.//DTD Facelet Taglib 1.0//EN" | "https://facelets.dev.java.net/source/browse/*checkout*/facelets/src/etc/facelet-taglib_1_0.dtd";> | <facelet-taglib> | <namespace>http://www.tdsecurities.com/jsf</namespace> | <tag> | <tag-name>header</tag-name> | <source>tags/header.xhtml</source> | </tag> | </facelet-taglib> | and is used as follows: <h:dataTable id="table" var="auditRecord" value="#{auditRecords}" rows="10"> | <c:header bean="#{auditLog}" columnName="id" columnLabel="ID"> | <h:commandLink value="#{auditRecord.id}" action="#{auditLog.select}" /> | </c:header> | </h:dataTable> | The link renders, but clicking on it yields: ERROR [org.jboss.seam.web.ExceptionFilter] -

it was supposed to execute auditLog.sort('id'), but apparently failed to evaluate the #{bean} expression, even though it was passed to the template via bean="#{auditLog}" Am I misunderstanding the limits for EL enhancements, maybe? Is it usable in this context at all?
