Hi, I have created a new product based on CMFDefault-Image, CMFCore-portal-content, and CMFDefault-Dublin... Do I need all these for the base classes, or is CMFDefault-Image the only one I need as it calls the others? I have setup the factory, portal-types, and skins and I can add new instances ok. I can edit and save changes to the properties of an instance. My problem is when I try to upload an image and save it I have insufficient permission (ZMI login box pops up). The the_editForm is setup with 'modify_portal_content' in the types tool actions tab. The the_editForm calls a python script with: req = context.REQUEST context.manage_upload( file=req[ 'file' ] ) req[ 'RESPONSE' ].redirect( '%s/the_editForm' % context.absolute_url() ) Is this script the problem or am I missing a permission somewhere? Thanks for your help. Richard
