The connection-status of a NETCONF node in topology-netconf stays in the connecting state does not change to connected after a NETCONF session is successfully established.

This appears to be caused by NetconfNodeHandler.onDeviceConnected() which simply resets attempts and does not propagate the status change to delegate:

    public synchronized void onDeviceConnected(final NetconfDeviceSchema deviceSchema,
            final NetconfSessionPreferences sessionPreferences, final RemoteDeviceServices services) {
        attempts = 0;
    }
