[Zope-dev] ZPatterns: Methods of specialits

[Steve Spicklemire]

Hi Roch'e,

   I'm guessing that getAllContactsForCustomer is a "DTML Method".  If
I remember correctly the third argument is a 'mapping object' that can
be used to augment the effective namespace available to the
method. Passing _.None should do nothing (I'm guessing you could just
use "getAllContactsForCustomer( this(), _ )" and it would work just
fine. This issue has been pretty much hashed to death here in the 
past. There is even a fishbowl proposal to 'fix it'.
