maybe because you haven't understand what the underscore namespace is about. Use <dtml-var "_['sequence-item'].id" > And btw. *never* access the ID of an object why with 'id'. You should *ever* use obj.getId(). -aj

Hi *<dtml-var "sequence_item.id"> When you use " " in dtml-var that is an expression. To access dtml sequence-item you must write it like this: <dtml-var "_['sequence-item'].id"> Dragos ----- Original Message ----- From: "Giuseppe Bonelli" <giuseppe.bonelli@tiscali.it> To: <zope@zope.org> Sent: Thursday, October 16, 2003 1:04 PM Subject: [Zope] DTML Document ids

Can someone explain to me why in the following code the line starting with * outputs a null string and the line starting with ** outputs the correct id of the DTMLDocument object ?

<dtml-var standard_html_header> <dtml-in expr="objectItems('DTML Document')" prefix="sequence"> *<dtml-var "sequence_item.id"><br/> **<dtml-var id><br/> </dtml-in> <dtml-var standard_html_footer>
