[Zope] Calling a dtml-method that has an extension (Was: Re: [Zope] Creating files on server)

[Gitte Wange]

Hi again,

For secure reasons I have dropped the idea of creating a physical file
on the server. Instead I can create the files dynamically inside Zope
and link to the method.

I have a method called fncSmileGenerate.smil

I call this from another method. Now when doing this I get the following
NameError:

Error Type: NameError
Error Value: fncSmileGenerate

The traceback is this:
Traceback (innermost last):

It seems to me that Zope won't recognize the .smil extension. Is it
possible in any way to make it do so ?
I need the extension because of RealServer.
