Thanks, Jacob. Great solution. I'd like to see that included in Seam. And btw, we need the endRoot attribute for the end-conversation element, too. Otherwise we cannot really end the entire conversation stack when a nested conversation throws an exception. | // pages.xml | | <exception class="javax.persistence.OptimisticLockException"> | <end-conversation endRoot="true"/> // end all conversations up to top-level long-running root conversation (inclusive) | <redirect view-id="/error.xhtml"> | <message>Another user changed the same data, please try again</message> | </redirect> | </exception> | cf. http://www.jboss.com/index.html?module=bb&op=viewtopic&t=112414&a...
