When changing: error about responsedata or responseheader is null.

[glsf91]

When changing something it is giving an error below which is disappearing too fast. Something about responsedata or responseheader is null.

I think it is caused by the following piece of code in RestClient.java:

  @Override
    protected void onPostExecute(Object o) {
        if(o instanceof String) {
            ResponseData responseData = null;

            switch (method) {
                case TYPE.GET.THERMOSTAT_INFO:
                    responseData = Converter.convertFromTemperature((String) o);
                    break;
                case TYPE.GET.ZWAVE_DEVICES:
                    responseData = Converter.convertFromDeviceInfo((String) o);
                    break;
                case TYPE.SET.SCHEME_STATE:
                    break;
                case TYPE.SET.SET_POINT:
                    break;
            }

            if (responseData != null && responseHandler != null) {
                responseHandler.onResponse(responseData);
            } else
                if (responseHandler != null) responseHandler.onResponseError(new NullPointerException("response data or responseHandler is null"));

In this part responseData will be always null when method TYPE.SET.SCHEME_STATE or TYPE.SET.SET_POINT is used.
