I think what Bruce is asking is agnostic of this sort of thing, but I imagine he's referring to a whole object. If I understand correctly, this sort of thing exists in the CMF to trigger workflow states. Independent of the CMF, though, what you would need (I think, not 100% sure) to do is wrap object constructors & methods that change them, (for TTW adding of objects) and use a custom PUT() and/or PUT_factory() in the ObjectManager-derived container or your object itself (in order to change what happens when a file is uploaded via FTP or DAV into that container); I haven't done this, but I think there are those on this list that have done something like this. If I was trying to figure out how this is done, I would try to ask folks who have been into any workflow-related product code...

From: "Bruce Eckel" <Bruce@EckelObjects.com>

Is it possible to automatically run an external method every time a file is saved? That is, is there some kind of file where I can say "when you're saved, call this method?"t

"Saved"? What do you mean? Saved to disk, or uploaded to Zope, or changing the properties? _______________________________________________ Zope maillist - Zope@zope.org http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
