In first place, I'm sorry I have done things in the wrong order: created a jira issue first (JBSEAM-344) and this topic second. The issue details are: Environment JBoss 4.0.4.GA JBoss Portal 2.4.0-Beta1 (used jems-installer-1.2.0.BETA) JBoss Seam 1.0.1.GA Description Followed this steps: - deployed the application in examples/portal using ant, as described in examples/portal/readme.txt - Entered http://localhost:8080/portal - Selected the SeamHibernate portlet tab, registered user, logged in... - Searched hotels, selected one of them, and pressed the "Book" button. In the Book Hotel screen, if the credit card number hasn't got 16 digits, a message is shown. After that, having entered 16 digits for the credit card, instead of the confirm screen, the "Search Hotels" screen is shown, with the message "No conversation". So, after a failed validation, the conversation is lost. In my own examples I've substituted conversational scope with session scope, just to see them working. Now I've tested the same use case using the latest jems installer, which bundles JBoss Portal 2.4.0-GA, and I was able to exactly reproduce the problem. may be I should try a previous version of JBoss Portal?
