We currently dispatch some object events to sublocations. I think
there's a problem with the current approach.
If I subscribe to IObjectModifiedEvent with something like this:
def handle(object, event):
...
I'll get notifications where object and event.object are different. This
happens for sublocation dispatches. This was very surprising, but it
makes sense -- there are cases when you'd want to get notifications like
that.
But most of my code looks like this:
def handle(object, event):
# ignore Zope's sublocation dispatches
if object != event.object:
return
...
I propose that we dispatch using both the original object and the
sublocation, along with the event. Handlers for these sublocation
dispatches would then look like this:
def handle(object, sublocation, event):
...
