[Zope] Re: external product writing to a file system ?

[Dr. Ross Lazarus]

Thanks for the suggestion, but I'd already looked through the DTMLtest
code and tried that - here's what I got

Sorry, an error occurred.<p>
<PRE>
Traceback (innermost last):
  File lib/python/ZPublisher/Publish.py, line 877, in publish_module

    (Object: &lt;string&gt;)
TypeError: argument 1: expected read-only buffer,
ExplicitAcquirerWrapper found

There must be some function which knows how to deal with the wrapper
which dtml objects have when I grab them from self.objectItems('DTML
Document'). Explicitly unwrapping them with str(foo) doesn't help much -
I just get a quoted html representation.

I'm still missing something here !
