Chris Rudd commented on JBSEAM-1546:
------------------------------------

Yea, I see that now after working on JBSEAM-1277 and JBSEAM-1294. :(

Although before the filter handles the exception the existing Seam context is still valid. So I guess in theory one could pull information about the request out of that. But it probably falls under the realm of "potentially bad / unreliable" things to do )

> The new events raised by the Exceptions component are nice, but would it be beneficial to raise and event before the handler is called so that one can interrogate the state of the request before its modified by the handler. (see JBSEAM-1285 - I would like to get the view that was being processed when the exeption occured.)

>       if ( Contexts.isConversationContextActive() )
>       {
>          Contexts.getConversationContext().set("org.jboss.seam.exception", e);
>       }
> + Events.instance().raiseEvent("org.jboss.seam.exceptionRaised." + cause.getClass().getName(), cause);
> + Events.instance().raiseEvent("org.jboss.seam.exceptionRaised", cause);
