Try making your __call__ signature:

def __call__(me,self,...):

And use 'me' to refer to the instance, self to refer to the object called
with.

Alternatively, just use REQUEST.PARENTS[0] to refer to the object you're a
method of.  See the DTML User's Guide.  (This only works if the method is
called from the web, though.)
