Con respecto a la llamada de Oracle en contrato inteligente

Tengo dos funciones que usan la llamada de Oraclize. Tengo que llamar a estas funciones una tras otra o simultáneamente.

Código de muestra para su referencia: -

pragma solidity ^0.4.0;

import "./usingOraclize.sol";

contract WeatherApiCall is usingOraclize {


      // oraclize callback types:
      enum oraclizeState { ForWeatherCondition, ForDistance }

      //Events
      event LOG_OraclizeCallbackForDistance(
                string result,
                bytes proof
      );

      event LOG_OraclizeCallbackForWeatherCondition(
                string result,
                bytes proof
      );

       // the oraclize callback structure: we use several oraclize calls.
       // all oraclize calls will result in a common callback to __callback(...).
       // to keep track of the different querys we have to introduce this struct.
      struct oraclizeCallback {
                // for which purpose did we call? {ForWeatherCondition | ForDistance}
                  oraclizeState oState;
      }
      // Lookup policy State from queryIds
      mapping (bytes32 => oraclizeCallback) public oraclizeCallbacks;

      address  public user;
      string public places1;
      string public from1;
      string public to1;
      uint public persons1;
      string public datetime1;          

      // constructor
      function WeatherApiCall() {
              OAR = OraclizeAddrResolverI(0x6f485C8BF6fc43eA212E93BBF8ce046C7f1cb475);
              oraclize_setProof(proofType_TLSNotary | proofStorage_IPFS);
              user=msg.sender;
      }
      //Function for distance retrieval
      function distanceRetrieve(string places,string from,string to,uint persons,string datetime) payable returns(bool sufficient) {

            places1=places;
            from1=from;
            to1=to;
            persons1=persons;
            datetime1=datetime;


          //   weatherconditionRetrieve(to1,datetime1);
            bytes32 queryId = oraclize_query(10,"URL",strConcat("json(http://www.distance24.org/route.json?stops='", places1 ,"').distance"));
          //  weatherconditionRetrieve(to1,datetime1);
            oraclizeCallbacks[queryId] = oraclizeCallback(oraclizeState.ForDistance);
           // weatherconditionRetrieve(to1,datetime1);
            return true;
      }

      function weatherconditionRetrieve(string to,string datetime) payable returns(bool sufficient) {



               bytes32 queryId =  oraclize_query(30,"URL", strConcat("json(http://api.openweathermap.org/data/2.5/forecast?q='", to ,"'&mode=json&APPID=d2e8279188c8649c17540f798c9cc972).list[?(@.dt_txt='", datetime, "')].weather[0].description"));
               oraclizeCallbacks[queryId] = oraclizeCallback(oraclizeState.ForWeatherCondition);
               return true;
      }
      //Function callback
      function __callback(bytes32 myid, string result,bytes proof) {

                 if (msg.sender != oraclize_cbAddress()) throw;
                 oraclizeCallback memory o = oraclizeCallbacks[myid];
                 if (o.oState == oraclizeState.ForDistance) {
                               LOG_OraclizeCallbackForDistance(result,proof);
                             //  weatherconditionRetrieve(to1,datetime1);
               }
                 else if(o.oState == oraclizeState.ForWeatherCondition) {
                               LOG_OraclizeCallbackForWeatherCondition(result,proof);
                 }

      }


}

Requisito:-

Tengo que llamar a distanceRetrieve()la función e inicializar los valores de las variables... Y también tengo que llamar weatherconditionRetrieve()junto con la distanceRetrieve()función o después de la distanceRetrieve()función.

¿ Cómo puedo programar weatherconditionRetrieve()dentro de distanceRetrieve()la función?

Lo he intentado de muchas maneras... pero falla... ¿Se agradece alguna ayuda?

Problema en la consola de Oracle mientras llamé a la función weatherconditionRetrieve() en la devolución de llamada.
