[Zope3-dev] KeyError when accessing ZopeTop

Mon, 7 Apr 2003 10:43:25 -0500

Whatever the rule or fix ends up being, there should be a meaningful
error that's raised and that makes it to the log. E.g.

   "undelcared XML namespace 'tal' in foo.pt at line n"

would have saved quite a bit of poking around.

Is an error getting burried some place along the way? Or is it just not
being raised in the first place?
