[Zope] conditional dtml-in ?

[Garry Steedman]

Michele,

you probably want to do something like this then (not that i'm saying 
DTML is the best way to do it... ;-):

<dtml-call "REQUEST.set('results', [])">
<dtml-in "objectValues('Folder')">
<dtml-if "hasProperty('invisible') and invisible">
<dtml-call "results.append(_.getitem('sequence-item'))">
</dtml-if>
</dtml-in>

<dtml-in results>
<li><dtml-var title>
</dtml-in>

cheers,

Garry
