[Zope] Handling created objects, not in the Zope database

Hi, I am trying to map data from my SQL database into a list of ZClass objects. For all entires found in the SQL database I want to create temporary instances of ZClass objects, so that I can use the different methods in the class. The dtml-in call attempts to validate these elemets which causes the pop-up logon box to appear. I have tried to turn of validation in the source code and all my elements are displayed properly. Is there a way to "force" dtml-in into not performing this validation? Best regards Petter Enholm Snapper as
