I'm always getting a null conversationStack component value whenever I use it. I've followed the instructions listed in the reference documentation, creating a pages.xml file, populating it with a page entry that matches a page view ID in my faces-config.xml file. I'm using MyFaces 1.1.2 (and Tiles and the Tiles Tomahawk support component), running on Tomcat 5.5.15... What am I doing wrong? TIA
