Anwser found via a search in the searchable list archive (though it would be a bit difficult). Anwser: An attribute name must never start with "_". Though, it has not been your intend, "_" is used as an attribute name in "existingFolder._". What you should use instead is: _.getattr(existingFolder,folder_id).manage_addFolder('subFolder') Keep in mind for the future, that the right operand of "." is always a name and never an expression! When you want to use an expression, you will use "getattr" instead.
