We've been on Struts 2.0.6 and a Tiles 2.0 pre-release
(2.0-20070207.130156-4) for a while now in the Roller trunk. After
seeing the recent news about XSS dangers we decided to upgrade to
2.0.9. before we make our next release.

So I downloaded 2.0.9. First, I found that the old Tiles listener
"org.apache.tiles.listener.TilesListener" is gone. After some
googling, I changed the listener to this:

  <listener>
    <listener-class>org.apache.struts2.tiles.StrutsTilesListener</listener-class>
  </listener>

That worked and once I made that change, Tomcat was able to deploy
Roller. I could view blog pages, but when I tried to access a Struts
page I got this error in the logs (on a page that worked perfectly
before the upgrade). And the page is unable to find any of its tiles.

DEBUG 2007-08-03 17:34:03,725 BasicTilesContainer:render - Dispatching

ERROR 2007-08-03 17:34:05,180 RoleSecurityTagSupport:doEndTag - Error

    at org.apache.tiles.jsp.taglib.RenderTagSupport.execute (RenderTagSupport.java:171)
...

After some more googling and gnashing of teeth, I tried changing the
root package in my Struts config file to extend "tiles-default"
instead of "struts-default" like so:

<!DOCTYPE struts PUBLIC
  "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
  "http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
  <!-- Weblogger default package -->
  <package name="weblogger" namespace="/roller-ui" extends="tiles-default">
...

But I got the same result.

Any idea what I might be doing wrong?
