Note that the "new way" stuff is only for Zope *later* than 2.8.x. In that case, you would define the function in a module somewhere on your $PYTHONPATH (e.g., in $INSTANCE_HOME/lib/python, or in a product) and then register it in a ZCML file which is included from your 'site.zcml' (in $INSTANCE_HOME/etc). > Anyway, thanks again. > > Terry > > | 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.
