[jira] [Commented] (WW-3848) NPE forwarding to tile without an
action class
[ https://issues.apache.org/jira/browse/WW-3848?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13426341#comment-13426341 ]
Lukasz Lenart commented on WW-3848:
-----------------------------------
Did you include Tiles Plugin ? If so your "default" package must extends "tiles-default" instead "struts-default".
I did a simple example base on the blank app and that [1] and it works like charm :-)
