[Zope] Scripts and permissions

[Timo Weggen]

Hi,

hello, this is my first post this list.
Im am using:
 (Zope 2.5.0 (source release, python 2.1, linux2) [SuSE Linux], python 2.2.0, linux2)
and have the following question:

Given that folder hierarchy:
root
+my_domain
 +scripts
  +generate_link (Python script)
 +projects
  +fooproject
   +index_html (DTML document)
where everything but my_domain/p rojects/fooproject/index_html
is owned by admin, only my_domain/projects/fooproject/index_html
is owned by some standard user (Authenticated role).

in index_html I want to call the script generate_link
like that:

<dtml-var expr="scripts.generate_link('bla.pdf')">The bla document.</a>

I'm  not using any proxy roles, and get the following traceback:


Zope Error

Zope has encountered an error while publishing this resource.

Every folder has at least View  and Access contents information set.
What else can be required?
(The script call even fails if it only consists of return "foo")

TIA
Timo.
