I have a DTML to ZPT question that the Zope Guru Community could probably easily answer. I am converting an index_html DTML Method to a Page Template, and the method/template renders the contents of the Folder in a directory-listing way (iterating over .objectValues([]). There is a particular folder that I have unchecked the 'Acquire View Permission' on the security tab, and the DTML version of index_html always seemed to pop up the login dialog... which is what I want... but the ZPT version of index_html errors with the stack trace shown at the end of this message. Do I have to explicitly bring up the login dialog myself when using ZPT to iterate over objects the user does not have authorization for?
