Except there is a problem: Inside 'DocumentTemplate' there's another 'DocumentTemplate' module. So doing: 'from DocumentTemplate.DT_Util import parse_params' ... tries to import DT_Util from the relative module. Then the fix is to do: 'from __future__ import absolute_import' ... except that doesn't work on Python 2.4. So the try: except seems to be the only way around here, unfortunately. or whatever the equivalent for Zope 2 is (I'm assuming it's Zope 2, since DT_Util is capitalized). Another option might be to switch this to use zope.documenttemplate. :) -- Sidnei da Silva Enfold Systemshttp://enfoldsystems.com Fax +1 832 201 8856 Office +1 713 942 2377 Ext 214 ___ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )
