[Zope] cannot import name SUPPORTS_WEBDAV_LOCKS

Hi, after upgrading from Zope 2.9.4-final to Zope-2.10.0 I have following problem while importing a Folder to Zope-2.10.0 which I have exported from Zope 2.9.4-final. Do you know where I'm doing something wrong? Error Type: ImportError Error Value: cannot import name SUPPORTS_WEBDAV_LOCKS Thanks, Ferhat __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
