Title: Dynamic columns with JSTL expressions

titleKey is only for resource bundles, it is same as bean:message

Subject: [displaytag-user] Dynamic columns with JSTL expressions

I am using displayTag to display a dynamic report where columns are stored in a metalist. I am using example from
http://displaytag.homeip.net/displaytag-examples-1.1/example-columnlist.jsp
And for most part the code work, however displayTag is not evaluating JSTL _expression_ correctly. For example, in the code it shows:

<display:table name="test">
    <c:forEach var="cl" items="${collist}">
                <display:column property="next" titleKey="${col.label}" escapeXml="true" sortable="true" decorator="com.amazon.biw2.webapp.taglib.ReportColumnWrapper" />
    </c:forEach>
</display:table>

However, in the html report instead of using value of col.label it's actually spitting "${col.label}" as it is.
I have also verified that jstl loop outside display tag works and it evaluates them correctly, but inside displayTag it's not evaluating the jstl _expression_. Any ideas.

Thanks in advance.

PS: I am initializing ${collist} same as the example code, i.e., it is an ArrayList where each element is Map and map contains 'label' and other properties.
