Yeah, I'm not seeing a "zope.component.interfaces.IObjectAdded" ...

I'm really quite certain I've done everything correctly ... The
interface, the registration of the handler, the handler itself and the
five:deprecatedManageAddDelete entry.

Still ... Nothing.

The content class uses __metaclass__ ... Could that be a problem?

class MapServerMap(PortalFolder, PortalContent, CLFMetadataImpl):
    """ Map Server Map Class """

    implements(IMapServerMap)

    __metaclass__ = AutomaticMultilingualProperties

That's the only major difference I see with my tool implementation that
uses IObjectAddedEvent successfully ...

Yes, well, I didn't show the code for my handler, but it is there:

def added(ob, event):
    """ Create the first page of a Map Text upon creation. """
    print "GOT HERE"
    try:
        if not hasattr(ob.aq_explicit, '1'): ob.invokeFactory('Map
Text', '1')
    except:
        pass

I notice however that your example uses
"zope.component.interfaces.IObjectAdded" vs. mine which uses
"zope.app.container.interfaces.IObjectAddedEvent" ...

Like I said, my event handler works for a tool ... But I guess maybe
that's not the right event registration ... I'll try your examples.

Thanks,

J.F.

If you want to react to an event you need to do two things:

- - mark your content item with an interface (you already did this)

- - code up a handler for the event

- - register your handler for the event

Only implementing some interface is not enough. You could have a
function like this somewhere:

def handleEvent(ob, event):
     """ Event subscriber for (IMapServerMap, IObjectAdded) events.
     """
     if event.newParent is not None:
         <do something>

and a registration like this:

   <subscriber
       for=".interfaces.IMapServerMap
            zope.component.interfaces.IObjectAdded"
       handler=".MyModule.handleEvent"
       />
