Subject Re: Issues with Struts Tiles
Date Sun, 06 Oct 2013 19:48:26 GMT
One thing, that I saw while looking at your code is that I have a different 
taglib: 

<%@ taglib uri="http://tiles.apache.org/tags-tiles" prefix="tiles" %>

and that I use
 <tiles:insertAttribute name="body" />
to include fragments.

Maybe this helps.

Regards, Pascal
