Bernard Labno commented on SOLDER-153:
--------------------------------------

Jason, sorry, but this issue is not finished.
Take a look at Phase.java:
try {
                handleAfterPhase(context, listeners, event);
            } catch (Throwable e) {
                queueException(context, e);
            }
            // stop timing
            if (timer != null) {
                timer.stopTiming();
                timer.logResult(
                      "Execution time for phase (including any PhaseListeners) -> "
                      + this.getId().toString());
            }

            context.getExceptionHandler().handle();

Well, the conversation context will be ended on handleAfterPhase and ExceptionHandlerDispatch.executeHandlers will be called on context.getExceptionHandler().handle();

So I can't have the ExceptionHandlerDispatch moved to Conversation scope (even with beans.xml modifications), cause the context won't be active.

> As we get into error pages, it's going to be useful to have the caught exception available via a named bean. I think this is just a matter of adding a dependent-scoped producer that reads the value of the current CaughtException from a field in the exception dispatcher.
> In Seam 2, the following two variables were available:
> org.jboss.seam.caughtException - the original exception that was caught
> org.jboss.seam.handledException - the exception cause currently being handled
> I think we could just map org.jboss.seam.caughtException to CaughtException...that way all the info is available, including the exception being handled, the original exception and the unwrapped stack.
