javax.ejb.EJBException: Application Error: no concurrent cal
I have a stateful session bean managing a seam-conversation injecting several JavaBeans with ScopeType=CONVERSATION. It must somehow depend on this combination because I could never reproduce this with the booking-example. I am using the login-files from the booking example so I should be redirected to the login-page but get the following exception. Any ideas what's wrong ?
