[Zope] FW: [ZC] 780/ 1 Request "dtml-var always renders to empty except if missing tag is added"

[Thijs Cobben]

All,

Mr. Dieter Mauer tipped me to forward this bug to zope@zope.org . I have
after posting been 'diffing' various versions of DocumentTemplate/DT_Var.py
but I honestly do not have a clue.

Could the root of the problem lie in the warnings I get about a 'Python C
API' ?

Please help!


Thijs
