I'm trying to not be a pain, but I can't quite get this to work and could use some guidance... First off I'm using v1.1b3 (milestone build) with a tomcat v4.1.18 server. I've divided my app into two modules each having it's own struts config files. I've setup tiles so that I have tiles-def.xml that will contain definitions common to both modules (definition site.mainLayout) and a tiles-*-defs.xml file for each module.
My apologies for the numerous attachments. I've removed most of the xml code in the attachments, but left enough valid code to convey the problem. To break it down all I'm doing is displaying a home page for each module. Each module has an action servlet that returns a success forward and here is where the problem happens.
The homepage servlet forwards to "home.page" which extends "site.mainLayout" and also uses "home.page.layout" as the put value for the "mainbody". This works as expected.
The knowledge servlet forwards to "knowledge.home.page" which also extends "site.mainLayout" but uses "knowledge.home.page.layout" as the put value for the "mainbody". Here is the problem... "knowledge.home.page.layout" is not found -or- executed. It just leaves a blank area on the screen.
A couple of permeation's I have tried with success.... IF I change tiles-knowledge-defs.xml to use "home.page.layout" instead of "knowledge.home.page.layout" it works... It finds the "home.page.layout" definition defined in the tiles-homepage-defs.xml file and displays it. The other thing I tried was changing the struts-knowledge-config.xml so that the knowledge servlet forwards to "knowledge.home.page.layout". This works also so I'm assuming that the "knowledge.home.page.layout" definition IS getting initialized via the plugin, but for some reason is not being used when I leave things as they are in the attached xml files.
Any clues on what I'm doing wrong would be greatly appreciated.
Thanks, aj
