An alternative would be a persistent subobject of the synchronized object (such that its modification does not modify the "bobobase_modification_time" of the primary object). I just notice that synchronization of structured (e.g. "ObjectManager") objects might be a problem. As subobjects might also be synchronizable, they, too, should get the correct times. -- Dieter _______________________________________________ Zope maillist - [email protected] http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
