I strugged today with a strange mounting problem: A colleague wanted to mount a storage under path "a" which has been formerly created while mounted under a path "b". Result: unless "a" and "b" are equal, the mounted object under "a" was empty. The analysis lead to http://collector.zope.org/Zope/1487 The mount-point documentation in "Zope/Startup/zopeschema.xml" is incomplete. The implemented behaviour unintuitive. You want to use "mount-point" specifications of the form "virtual_path:real_path" and not "path" (as the documentation suggests). -- Dieter
