[Zope] How to check for a folder's existence and create it if itdoesn't exist?

[Kees de Brabander]

I'm not shure if I understand you correctly, but this might do what you're
looking for:

<dtml-call REQUEST.set('folderExists', 0)
<dtml-in expr="objectValues('Folder')">
  <dtml-if "id=='2001'">
    <dtml-call REQUEST.set('folderExists', 1)
  </dtml-if>
</dtml-in>
<dtml-if folderExists>
<dtml-else>
  <dtml-call manage_addFolder....>
</dtml-if>
