[jbossseam-issues] [JBoss JIRA] Commented: (JBSEAM-2600) Exception handling - Fix the exception handling in Seam

Exception handling - Fix the exception handling in Seam ------------------------------------------------------- Key: JBSEAM-2600 URL: http://jira.jboss.com/jira/browse/JBSEAM-2600 Project: JBoss Seam Issue Type: Feature Request Components: Core Reporter: Shane Bryzak Fix For: 2.1.0.GA Currently we have at least one serious race condition in our pages.xml exception handling, related to redirect/message passing. I can reproduce (JIRA case is open) lost messages on exception redirect. Also, clean up the #{exception} and #{handledException} stuff - which might fix the issue as a side effect. I want one exception instance I can access in EL, not two. I want to be able to call getRootCause() on it to unwrap the root exception. Of course the root cause is the one I specify in pages.xml as the one that is handled, but the #{exception} should always be the wrapper. In any case, a clear and reliable (working in all situations) strategy needs to apply here.
