Hello, I recently created a product which adds a folder, with multiple dtmldocuments inside of it, effectivly creating a site immedatly. However, even though I can add folders and documents easiliy, I can't seem to create properties! It keeps giving me the Attribute error: aq_base. Here is the code for the function that does the work: def manage_addMemberSite(self, id, title='',REQUEST=None): """Add a MemberSite folder.""" try: user=REQUEST['AUTHENTICATED_USER'] except: user=None folder = MemberSite(id, title) # _setObject must be the Zope hook that actually stores this instance in # the ZODB self._setObject(id, folder) folder.manage_addFolder(id='Images', title='') folder.manage_addDTMLDocument(id='index_html', title='', file=index_body) folder.manage_addDTMLDocument(id='navbar', title='', file=navbar_html) folder.manage_addDTMLDocument(id='content', title='enter page content here', file=default_dd_html) folder.manage_addProperty(id='nav_color', value='#483D8B', type='string') folder.manage_addProperty(id='content_color', value='#F0E68C', type='string') folder.manage_addProperty(id='background_color', value='#FFFFFF', type='string') if REQUEST: return self.manage_main(self, REQUEST, update_menu=1) The folder.manage_addProperty(id etc etc) does not work. I have been looking all over, have looked to where the error seems to stem from, (the valid_property_id function in the PropertyManager.py) but I can't seem to find out whats wrong. Does anyone have any ideas? Please respond ASAP.
