Any further hint if I use Formulator?  The patch worked for my simple
example but my real application uses Formulator.  If I enhance my simple
example by a Formulator object the initial problem raises up again:

   Zope Error

   Zope has encountered an error while publishing this resource.

   Error Type: NameError
   Error Value: global name 'field_iditem' is not defined

Or should I discuss this issue on a Formulator related list?

Kind regards

Here the relevant objects created by the (patched) Z Search Interface:
