But the session scope is "wider" than what you need for this, and it may give unexpected results if you happen to get two requests that fail for different reasons from the same user (part of the same session, so they overwrite each others error data). The request scope is much more appropriate for this kind of thing.

To pass dynamic data to an error page, store it in the request scope instead.
