[Zope-dev] Calling parent class method when method is overridden in current class?

[Phil Harris]

Steve,

I'm pretty sure I've tried that but I'll try it again and see what happens,
hang on I'll be right back.

Right I'm back, I thought I'd tried it and I had, I get this error:

Error Type: TypeError
Error Value: call of non-function (type None)

Traceback (innermost last):
  File D:\ZOPE_2~1.2_D\lib\python\ZPublisher\Publish.py, line 222, in

which seems to be telling me that DTMLDocument.index_html is None, weird eh!

TFT (thanks for trying)
