ZODB will detect conflicting write transactions and raise ConflictError that you're supposed to catch and retry up to a certain reasonable number of times (3 or 5).

Means you can not lock/unlock objects directly through the Zope UI (except the global webdav lock manager in the ZMI for _unlocking_ content).

Look at Plone utilizing the webdav locks for app-level locking support. Or: you can the API in Zope for using the webdav locks (somewhere in the 'webdav' module, check yourself). -aj pgpFtOFSS4kG8.pgp Description: PGP signature ___ For more information about ZODB, see the ZODB Wiki: http://www.zope.org/Wikis/ZODB/ ZODB-Dev mailing list - ZODB-Dev@zope.org http://mail.zope.org/mailman/listinfo/zodb-dev
