[Zope] different namespaces in a python script by calling it by<dtml-var xxx> and <dtml-var "xxx()">?

[Grégoire Weber]

Thanks Chris,

your answer helped me! 

But I am not really satisfied in general about the solution.
I know it's not your fault!

I have additional parameters so I replaced the '_.None'
by the parameters like this (as I suppose, the _.None
is only used if there are no parameters at all):

   <dtml-var "xxx(anypar='foo_par',_=_)">

without '_=_' it does not work as expected.

You're damn right! :-(

Questions which turn up (just for interest):

1) Why isn't this done automagically by setting the 'Namespace' 
   thing in the bindings tab to '_'? So that the caller does not 
   have to grant access to '_' to the calles Python Script 
   explicitly?

2) Isn't there really any possibility for the Script to access 
   the '_' namespace of it's own? It seems that I have access
   to the '_' namespace version which is set up at the
   beginning of the request.

3) Why do DTML know about the actual namespace of the calling
   methods and Python Scripts not?

It seems to me that Python Scripts do not at all have the same 
behaviour as DTML methods have. :-(

P.S.: Is there a documentation about thsi anywhere?

-------------------------------------------------- xxx script
## Script (Python) "xxx"
##bind container=container
##bind context=context
##bind namespace=_
##bind script=script
##bind subpath=traverse_subpath
##parameters=anypar='foo_default'
##title=
##
if _.has_key('sort_order'): return (_['sort_order'],anypar)
else: return ('sort_order not defined',anypar)

------------------------------- xxxcaller dtml method snippet
<dtml-let sort_order="'foo_sort_order'">
<dtml-var xxx><br>
<dtml-var "xxx(anypar='foo_par',_=_)">
</dtml-let>
