Hi, I found something strange in metadata when copying a persistent object.
My situation is the following: I have a container with some elements inside. I create a copy of this container using zope.copypastemove.ObjectCopier(my_container).copyTo(my_container.__parent__) (Actually I use zope.copypastemove.interfaces.IObjectCopier(my_container) but this calls the adapter mentioned above.) Side note: Is this the right way to copy an persistent object nowadays? This happens tho dublin core metadata then: As zope.dublincore.timeannotators.CreatedAnnotator is subscribed to zope.lifecycleevent.IObjectCreatedEvent it gets called as the ObjectCopiedEvent is a subclass of ObjectCreatedEvent. The copy of the container gets a new creation date set in its metadata. But zope.copypastemove.dispatchToSublocations calls the subscribers for the sublocations using zope.component.subscribers((sub, event), None) So the zope.dublincore.timeannotators.CreatedAnnotator does not get called as it is not registered for (object, event) but only for (event,). This leads to a strange situation: the metadata of the copied container get updated but not the metadata of its contents. This behavior has not changed since version 3.4.0 which was about 2,5 years ago. I think this is a long-standing bug and it should it be fixed in zope.dublincore by registering the subscribers for (object, event)? (Additionally or exclusively, I'm not sure.) Any thoughts?
