[Zope-dev] standard_error_message and displaying non-html content.

Thu, 18 Oct 2001 14:21:59 -0400

I wanted to throw 2 cents in to this thread from my previous
problems/questions about error_message.
I think they are slightly related.
Maybe someone can filter my newbie-isms and use some of this in the Dogbowl.
I would like to have more control over the standard_error_message
auto-rendering of error_message and error_tb.  These should be treated more
like "typical" methods in Zope to be consistent with everything else.  (like
standard_html_header)  ;)
