Here is the file that I am trying to insert into the tiles layout (viewrequest.jsp): <%@ taglib prefix="s" uri="/struts-tags"%>

This is the layout page I am including the above file in (waitlayout.jsp): <%@ taglib uri="http://tiles.apache.org/tags-tiles" prefix="tiles"%> <%@ taglib prefix="s" uri="/struts-tags"%> " /> ${application.title}

I don't suspect it is a tiles issue, but appears to be an issue with iterator based on the stack trace. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
