[Zope-dev] Help needed: why is this DTML not working in zope 2 ?

[Gilles Lavaux]

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_String.py", line 502,
in __call__ try: return render_blocks(self._v_blocks, md) AttributeError:

has someone a solution ??

Thanks,

Gilles
