I am trying to use the MountedStorage Product: http://www.zope.org/Members/natsukashi/Products/MountedStorage I am using Zope 2.4.1 ZEO 1.0b4 Win 2000 I want to mount a Berkeley Storage to use for CoreSessionTracking with ZEO But if I try to add an instance of MountedStorage I get the following traceback: <strong>Error Type: AttributeError</strong><br> <strong>Error Value: MountedStorage</strong><br> . . . Traceback (innermost last): File D:\PROGRA~1\WEBSIT~1\lib\python\ZPublisher\Publish.py, line 223, in publish_module File D:\PROGRA~1\WEBSIT~1\lib\python\ZPublisher\Publish.py, line 187, in publish File D:\PROGRA~1\WEBSIT~1\lib\python\Zope\__init__.py, line 226, in zpublisher_exception_hook File D:\PROGRA~1\WEBSIT~1\lib\python\ZPublisher\Publish.py, line 162, in publish File D:\PROGRA~1\WEBSIT~1\lib\python\ZPublisher\BaseRequest.py, line 340, in traverse File D:\PROGRA~1\WEBSIT~1\lib\python\App\FactoryDispatcher.py, line 102, in __bobo_traverse__ File D:\PROGRA~1\WEBSIT~1\lib\python\App\Product.py, line 137, in _product (Object: LockableItem) AttributeError: (see above) Any suggestions? Or can someone give my some hints how to install ZEO with CoreSessionTracking using a mounted BerkleyStorage. Cheers Jens
