[Zope-dev] Re: Can't fathom 'method-populated' selection lists in Zclasses

[Bob Marshall]

Hi Dieter,

  Thanks anew for your continued help and advice. I've downloaded and 
installed your Reference product as suggested. I see where it's coming from 
in general terms, but it's way beyond me to get it working. Guess I'm just 
too dumb. So I will indeed place this issue in the 'bucking horse' category 
and walk down another street...

  Cheers

  Bob
