[Zope] DTML into Python for Formulator

[cgreen]

Dieter;

Thanks for the reply.... after I posted the original question, I got off 
my lazy butt, searched a few sites, and
came up with this: (hmmm...... a new acronym, maybe -- GOYLA?? [Get Off 
Your Lazy A--])

results=[]
for object in context.objectValues('STX_Document'):
   if object.getProperty('topic') != '':
   if tuple not in results:
       results.append(object.topic)

   results.sort()
  
return results


as a python script, instead of the DTML method:

<dtml-call "REQUEST.set('tmp',{})">
<dtml-in 
expr="_.sequence.sort(PARENTS[0].objectValues(['STX_Document']), 
(('topic', 'nocase'), ('title', 'cmp'),) )">
<dtml-call "REQUEST['tmp'].update({topic:''})">
</dtml-in>
<dtml-in "REQUEST['tmp'].keys()">
<dtml-var sequence-item>
</dtml-in>

Just thought I'd share this for anyone following the thread.... I hate 
seeing questions asked in newsgroups without answers......
