I created a JIRA issue here: http://jira.jboss.com/jira/browse/JBSEAM-589. IMO it doesn't matter if one transmits no or a not existing conversation id - the result is the same: no conversation is restored. Further most - if not all - pages in a pageflow rely on conversations (why would one mention the no-conversation-view-id attribute if one doesn't need a conversation?). However, if you are worried about backwards compatibility you could perhaps add an additional parameter somewhere. Either globally in faces-config or components.xml or on a per page base in the pages.xml of pageflow files so that everyone is happy ;) Thanks for your attention. PS: while you are working at the pageflow stuff please have a look at http://www.jboss.com/index.html?module=bb&op=viewtopic&t=97218. IMO this would be really useful :) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3993514#...
