[Zope] Bug in Zope 2.3.1b3 PythonScripts (I think)

[Mayers, Philip J]

My earlier mail about the PythonScript calling DTML method appears to have
been confirmed, at least on the RedHat 6.2 sparc platform. I just downloaded
a clean installation of 2.3.1b3 onto another machine and did a clean build -
no extra products, no imports, and the following PythonScript in the root:

print context.standard_html_header(context,context.REQUEST)
print context.standard_html_footer(context,context.REQUEST)
return printed

Gives this traceback:

Error Type: TypeError
Error Value: call of non-function (type list)


Traceback (innermost last):

Identical code functions as expected under Zope 2.3.0 release code on the
same machine. I can't see any obvious differences in either
Products/PythonScripts or DocumentTemplate/ but I'm hardly a Zope core
hacker... I guess it must be in the acquisition code.

Suggestions welcome - I tried to put this into the Collector but got various
combinations of unhelpful error messages (Pricipia Unavailable being the
principle one) - oh well <grin>

Suggestions welcome...

Cheers,
Phil
