[Zope] Python Script REQUEST namespace not found.

[H.Tan]

this is interesting to know that there is a magic around ZPublisher.
But I believe, there must be a definite answer to get Python Script reading
variable in REQUEST namespace.

I tried using Session object and it works.

Below is my code:

---------------------------
DTML-document: helloDoc

<dtml-call "SESSION.set('name', 'john') ">
<dtml-var hello>

---------------------------------
Python Script 'hello'
Parameter name='world'

session=context.REQUEST.SESSION
l=session['name']

return "Hello %s" %l

----------------------------------

The result is: 'hello john' which is correct result.
