[opencms-dev] Problem with CmsFlexController when using Spring & Tiles

[Mathias Lin]

Hi,

I use Spring integrated into OpenCms7.0.5 and now want to break the
templates into smaller parts using Tiles. 

Tiles are configured so far, and in my template I put 

<%@ taglib prefix="tiles" uri="http://jakarta.apache.org/struts/tags-tiles"
%>
...
<tiles:insert name="content" />

When opening the page I get the following exception in
CmsFlexController.java:693.
I found exactly this problem posted here: 
http://www.opencms-forum.de/opencms-forum/viewthread?thread=3278
http://www.opencms-forum.de/opencms-forum/viewthread?thread=3278  but no
resolution to it.

I also tried to turn off the Flex Cache in opencms-system.xml, but after
Tomcat restart, I still get the same error.

Anybody who got Tiles running with OpenCms7.0.5?
