The editor issues the replication request to an incorrect path.
In my setup the editor is called on /content/ca-config/en/configuration.htm
On /content/ca-config/en there is the property sling:configRef set to /conf/ca-config/content/en
In the editor when I hit "Publish this page", I see the /bin/replicate.json request with the parameter path set to " /content/ca-config/en/config". But this path does not exist on my local instance.
So from my point of view this feature does not work.
