JBoss EL issue

[phenix098]

I am using <c:if tag inside rich:dataTable. the value expression "not empty ${not empty row['H.Locked.Hidden']}" always false

<rich:dataTable id="data" rows="20" value="${backupBean.data}" var="row" >
    <c:if test="${not empty row['H.Locked.Hidden']}">
        Locked
    </c:if>
</rich:dataTable>

The backupBean.data is a List of Map (List<Map<String, String>>). I am using Seam 2.1.1.GA (with tomcat 6.16, JSP2.1, Servlet 2.5, JSF 1.2)

Is it because of the incompatible of JBoss EL and JSP2.1?

BTW, where I can get JBoss EL source code? Thanks

I'm not sure of the exact syntax of your EL expression.  However, you should replace the <c:if> with something like this:

<h:outputText value="foo" rendered="#{not empty row}"/>

The JSTL <c:if> tag is not used very often in JSF/RF.
