Hello, I am a little bit disappointed not getting any echo from my previous question, so I report it. Maybe my dtml is wrong for zope2, but I would appreciate to have some explanation from more experienced peoples. If I can not find a solution, we will have to keep our zope1 production server, and it will be the end of the Zope story in my company :-( So my question was : I want to display the content of a site starting from a folder called 'Site' with a tree tag. I want also to render immediately inside the tree the documents with an ID=='PUBLIC_Doc'. In Zope 1.x I have a working dtml method like this: <!--#var standard_html_header--> <!--#tree Site branches_expr="objectValues()" sort=id skip_unauthorized--> <b><!--#var id--></b> <!--#if "_['id']=='PUBLIC_Doc'"--> ## <!--#try--> <!--#var "_[_['id']]"--> <!--#except--> <!--#var Except_Message--> <!--#/try--> ## <!--#/if--> <!--#/tree--> <!--#var standard_html_footer--> Unfortunatly for me , with zope 2.1.6 i get an error when I try to render the 'PUBLIC_Doc' document: ..... PUBLIC_Doc !# Error type:AttributeError Error Message: Error Message:__call__ Error TB:Traceback (innermost last): File "/usr/lib/python1.5/site-packages/DocumentTemplate/DT_Try.py", line 221, in render_try_except result = render_blocks(self.section, md) File "/usr/lib/python1.5/site-packages/DocumentTemplate/DT_Util.py", line 335, in eval return eval(code,globals,d) File "", line 0, in ?
