Hi guys,
I've followed the wiki [1] for handling server errors. (e.g. 500, 404)
The page that I have made for this displays fine. But when I try to add
a button for the user to navigate to another page, it does nothing. Such
a button is necessary because simply hitting the "back" button on their
browsers will most likely leave them at the same page, staring at the
error message.
I have tried both h:commandButton and h:commandLink. Is it normal for
navigation away from one of these pages to fail? My button links to an
action on a session-scoped managed bean. The action works fine from
commandLinks in other pages, even after an error occurs (in cases where
the back button gets me back to a non-error page)

Below are my relevant source.
