Hi all, The product I am using (KebasData) has a property called render_method, which is the name of a dtml method that gets called from within the index_html of an instance, like so: <dtml-var "_[render_method]"> My render method is called viewResults and it calls a script (Python) called PageListOutput, which is described in the ZopeLabs recipe found at http://www.zopelabs.com/cookbook/1019946889. Normally it is possible to display the rendered KebasData like so: http://mysite.org/kebasdata_instance which has always worked for me but not this time. What is strange, is that it works fine when called like so: http://mysite.org/kebasdata_instance/viewResults which, to my feeble understanding, should be no different.. The traceback: File /usr/sites/www/zope/lib/python/DocumentTemplate/DT_Util.py, line 159, in eval (Object: PageListOutput('.',page,step,_.len(match))) (Info: _) File <string>, line 2, in f NameError: (see above) Can anyone tell me what is missing? Details: Zope 2.5.1, Python 2.1.3 (binary), FreeBSD4.3 Thanks, Ken
