[Zope] Iterating over meta-entries fields in Metapublisher

[Juergen Osterberg]

dear all,

I am using metapublisher: how do I iterate in dtml over one field of my
meta-entries in order to
change that field in all entries? I tried to use the editEntry method:

<dtml-in entryIds>
  <dtml-call "REQUEST.set('f1014038858', 'whatever')">
   <dtml-call
"editEntry(id=_['sequence-item'],title='',REQUEST=REQUEST,RESPONSE=RESPONSE)
">
</dtml-in>

and also directly the  manage_editMetaEntry method which the editEntry uses.
Neither of those worked as I did not manage to pass the variable to the
method? Or may be I have not understood the REQUEST stuff yet?

Best regards

Juergen
