[Zope-dev] How to aquire from Context?

[Chris Withers]

Matt,

Evan Simpson came up with some external methdos that do exactly what you want
about 6 months to a year ago.
If you search the zope.nipltd.com archives for zope@zope.org and
zope-dev@zope.org you may well be able to find what you're after :-)

cheers,

Chris
