[ https://issues.apache.org/jira/browse/TILES-561?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15409696#comment-15409696 ]
Gokcen Guner commented on TILES-561:
------------------------------------
[~nlebas], I don't get why you closed this issue. I am having same issue with Tiles 3.0.5. Should I create a new ticket?
If there is a solution, I think it should be shared before closing any issue with "*Won't Fix*" status.

> Demo project is attached but problem is throughly discussed at http://stackoverflow.com/questions/13126201/struts2-tiles-org-apache-tiles-extras-complete-completeautoloadtileslistener-int . Seems there is no solution to it because I have spent hrs struggling.
> In Short:
> *web.xml*
> <listener>
> <listener-class>org.apache.tiles.extras.complete.CompleteAutoloadTilesListener</listener-class>
> </listener>
> *generating error*
