Hi, I currently use a custom subclass of BTreeFolder2 to store my site's users profiles (currently 3700). I've noticed several problems : - several keys (= user ids) are duplicated in this folder ; in the ZMI, these duplicated keys appear at the start of the list, unordered. - some keys are duplicated more than once ; if I try to delete one of them, the other duplicated keys are kept and can't be deleted, because the object doesn't exist !!! - if I try to cut a duplicated object and paste it into another folder, I receive an error message, saying that I'm trying to paste an object from a foreign database connection !!! So here are my questions : - is it a bug in BTreeFolder2 ?? Can I avoid this ? - are duplicated keys pointing to the same object or no ? - is it possible to repair this, without losing currently stored objects ?? Thanks for any help...
