The old way to do that we be to derive your own folder class and override '_setObject' / '_delObject' to add your semantics. The new way (for Zope >= 2.9) would be to register a subscriber for the "container" events which are published automatically. Something like (untested):: def update_keywords(event): keyword = getattr(event.newparent, 'keyword', None) event.object.keyword = None event.object.reindexObject() and then in ZCML:: <subscriber for="zope.app.event.objectevent.ObjectEvent" factory="Products.yourproduct.events.update_keywords" Tres. - -- =================================================================== Tres Seaver +1 202-558-7113 [EMAIL PROTECTED] Palladion Software "Excellence by Design" http://palladion.com -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFER7/g+gerLs4ltQ4RAjcHAJ9WqoFcbrNIC9h3M5jYEZ8Bmq2jMQCeMjSh 7zE2AI2+rNc39s3bhOMsb4E= =yYJw -----END PGP SIGNATURE----- _______________________________________________ Zope maillist - Zope@zope.org 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 )
