After having installed the YT 4.0.1 latest build as a standalone WAR in JBoss 5.1.0 GA, everything seems to works smoothly, except when I click the "Agile Board" button.
I'm running the Free license for testing purposes on my dev laptop. I had to remove the xerxes.jar from WEB-INF/lib/ in order to get JBoss to boot properly with YT deployed.
Could this have anything to do with the error I'm experiencing?
