html-el: page attribute doesn't accept run-time expressions
In struts-html.tld, the page attribute allows run-time expressions:
<attribute>
<name>page</name>
<required>false</required>
<rtexprvalue>false</rtexprvalue>
</attribute>
However, in struts-html-el, the page attribute does not allow run-time
expressions:
<attribute>
<name>page</name>
<required>false</required>
<rtexprvalue>false</rtexprvalue> <--
</attribute>
Is this a bug?
The reason I ask is because the following code works fine in Tomcat 4.1.24:
<%-- Get Javascript List --%>
<tiles:useAttribute id="scriptList" name="scripts"
classname="java.util.List" ignore="true"/>
<c:forEach var="js" items="${scriptList}">
<script type="text/javascript"
src="<html-el:rewrite page="${js}"/>"></script>
</c:forEach>
But in Tomcat 5.0.4, maybe things are stricter or something, but I get the
following error:
org.apache.jasper.JasperException: /layouts/baseLayout.jsp(22,17) According
to TLD or attribute dire
ctive in tag file, attribute page does not accept any expressions
If I change it to the following, everything works fine:
<c:forEach var="js" items="${scriptList}">
<script type="text/javascript"
src="<%=request.getContextPath()%>${js}"/>"></script>
</c:forEach>
Thanks,
Matt

Hm, although JSP 2.0 may actually use it for EL-based tags as well. I'm not that
familiar with the details of 2.0, so that might actually be the problem. You
should be able to verify that by trying to use an EL expression in any of the
Struts-EL tags. Which means you'd also need to make sure you're using JSTL 1.1
since those tags will run into the same problem.

Does this work:
<c:forEach var="js" items="${scriptList}">
<script type="text/javascript"
src="<c:url value="${js}"/>">
</script>
</c:forEach>
None of the EL tags should have <rtexprvalue> set to true, right? That's for JSP
expressions, not EL expressions.
