[Zope-dev] Deleting objects in BTreeFolder

[sean.upton@uniontrib.com]

Wondering why calling _delObject() in BTreeFolder, which inherits
_delObject() from ObjectManager, doesn't work with BTreeFolder._getOb(), and
I have to use BTreeFolder._delOb() to delete a contained object in a
BTreeFolder.  Is this incompatibilty by design?

I run into trouble using _delObject (traceback #1 below), getting a
deliberately raised AttributeError, but changing this to _delOb raises a key
error when calling 'del tree[id]' on line 195.

Thoughts?
