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. Fred R.
