Is there a way (in JSF 2) to catch a Conversation timeout and redirect a user to a new page? I’m getting nasty NullPointerExceptions when the conversation times out.
I could redirect the user on all NPE’s, but that seems like too big a net.
This is a bug with Weld 1.0.0 the RI for CDI
https://jira.jboss.org/browse/WELD-550
This has apparently been fixed in the Weld trunk, I don’t know in which release it’s available. In trunk, a
org.jboss.weld.context.NonexistentConversationExceptionexception is thrown, when trying to access an expired conversation. This Exception can be trapped with a customExceptionHandler, and redirect the user to an appropriate page. See this blog for more details on creating an customExceptionHandler:http://weblogs.java.net/blog/edburns/archive/2009/09/03/dealing-gracefully-viewexpiredexception-jsf2
