Unexpected NodeCreated?

Hi all,

I'd like to know if the next flow is right?

   1. Create Ephemeral Sequential at "/parent/" > OK [/parent/0000000000]
   2. Remove zpath [/parent/0000000000] > OK
   3. exists(/parent/0000000000,true,null) > NONODE
   4. Remove zpath [/parent] > OK
   5. Create Persistent zpath [/parent] > OK
   6. Create Ephemeral Sequential at "/parent/" > OK [/parent/0000000000]
   7. EventType.NodeCreated [/parent/0000000000] triggered.

Is it valid to receive a "NodeCreated" event or watcher should had been
removed with parent zPath removal?

BR,
/César.

Cesar,
This is expected behavior.
