[Zope] a problem with "skip_unauthorized"

Hi ! I use zope 2.4.0 and i have a problem with "skip_unauthorized". I want to publish some documents, but obviously, anonymous users are not allowed to view administrator's documents. So i use "skip_unauthorized" in the "in" tag, but an error is raised : You are not authorized to access xxx Which means that "skip_unauthorized" does not work !. I dont understand. Have you an idea ? <dtml-in "arch_actualites.objectValues('doc')" reverse sort="Date" skip_unauthorized> <dtml-var "publish('actutitle','actucontent',_['html_resume'],1)"> </dtml-in> Thanks. Sylvain
