The most reliable way to call DTML from ZPT is using a Python
expression, so that you can explicitly pass the client object and
request mapping.  Try something like this:

tal:define="result here.my_dtml(None, request)"

or

tal:define="result here.my_dtml(here, request)"

The problem that you're having is a change in the implicit DTML call
code to make ZPT variables available to called DTML code.
