[Zope] Adding zclass inside folder with python

Hi, I've tried everything I can think of and am probably missing something obvious - help... I'm trying to (1) Create a folder, then (2) Add a new zclass inside that folder. Instead, the zclass is being added in the same space as the folder: - What I want: New Folder New ZClass - What's happening: New Folder New ZClass =========== The code that doesn't work: request = context.REQUEST pbuildid = request.pbuildid # Add a new folder with id=pbuildid context.manage_addFolder(id=pbuildid) # Add a new instance of the ZClass inside new folder instance = context.pbuild.createInObjectManager(request['id'], request) instance.propertysheets.pbuild_properties.manage_editProperties(request) =========== TIA, AnThu Nguyen
