[Zope] The HOW-TO "Build a Searchable Job Board"

[Rubinstein Fredrik]

		Hi there.
I'm trying out the aboved named how-to.
However the following piece of code 

<dtml-call "REQUEST.set('ts', ZopeTime())">
<dtml-call "REQUEST.set('id',_.str(_.int(ts)))">

<dtml-with "Dokument_skapa.createInObjectManager(REQUEST['id'], REQUEST)">

  <dtml-call "propertysheets.dokument_info.manage_editProperties(REQUEST)">
  <dtml-call reindex_object>

</dtml-with>

Generates the following error message

Zope Error
Zope has encountered an error while publishing this resource. 
Error Type: AttributeError
Error Value: _setId
Has anybody out there encountered this error and what on earth do one do
about it.
With kind regards.
