Seam managed exception handling and stacktrace

As far as I understand the functionality of seam managed exception handling via pages.xml to redirect to somathing like an error.xhtml there is no posibility to also print the error stacktrace on the view beside enabeling debug page.

If you look at the wiki source it may help... I noticed

./examples/wiki/view/message.xhtml:
