[Zope] Automatically run an external method?

[sean.upton@uniontrib.com]

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...

"Saved"? What do you mean? Saved to disk, or uploaded to Zope, or changing
the properties?
