| The trouble with @Conversational is that lots of methods of the component can get called before an action method. There may not even be an action method.
I think I discovered that one my own. It seems like I have some cases where I think it should work but doesn't...
Guess I'm back to the design mode. I'm trying to put in a framework that handles exceptions - basically all exceptions should redirect to an error page that displays FacesMessages if present.
The specific case I'm working on is:
a) user submits a page that throws a BusinessExcpetion
b) BusinessException is annotated with @Redirect
c) error page is displayed correclty
d) user in a different window corrects the error
e) user than returns to the original window (still displaying the error message) and hits the back button
f) the same page is resubmitted - an ugle error is generated basically saying that a conversation is already started and to use (Begin join=true)
- however, the conversation was rolledback and I believe destroyed in #b/c
I've read some of the other threads/JIRA about using Servlets / modifying JSF, so I'll think about it some more. Anyway, just curious how other handle generic exceptions rather than showing the ugly app server error messages or generic http messages.
