cometVisu UI - HTTP Error 404 - Openhab 2 snapshot 25/9

Hi
I have installed Extensions/UI/CometVisu but get the HTTP ERROR 404, when I try to start it.
http://x.x.x.x:8080/cometvisu/?config=demo
HABMIN installed from the same place is working fine.
What am I doing wrong?

I am seeing the same problem. Did you get this working? If so, how?

No sorry, I switch to Habpanel
