[Zope] problem with a list of files

Hi everybody, I am trying to store a list of files in context.REQUEST.SESSION. In order to achieve this I do files = container.Entries.objectValues('File') and later session=context.REQUEST.SESSION session['mylist']=files and I get the error Error Value: Attempt to store an object from a foreign database connection I suppose this is because Zope tries to store the files, and I only need to store the reference to them. Somebody knows how to do it? thank you. _______________________________________________________________ Yahoo! Messenger Nueva versión: Webcam, voz, y mucho más ¡Gratis!
