I've been playing around with Shane's excellent APE (http://hathaway.freezope.org/Software/Ape). Cool concept. However it seems to be a bit more touchy to certain objects than the default ZODB filestorage. In other words: Objects such as Btreefolder2 and Group User Folders work using default ZODB filestorage, but break with APE. Maybe it's just my environment, but on the other hand APE might (on purpose?) be more touchy. So I don't know whether to file this as a bug or not -- or if it's APE's or the other projects fault. Any thoughts?
