ZODB Mountpoint distributed with Plone 4.1.2 always seems to create OFS.Folder even if the container-class is specified.
Also getting a "KeyError: item already present wih same id" due to _setObject and _setOb both being called.
Am trying to mount a plone.app.folder.folder.ATFolder from a separate Data.fs.
I was able to fix this by removing some code to do with a “Faux” object in MountedObject.py
Seems this is not needed anymore and is getting in the way of things.
