Mi proyecto es Cordova + React (es6). Tengo algunos problemas con el uso de setState ().

los datos que se pasan al estado no están vacíos. Pero, al pasar los datos al estado, recibo resultados El estado está vacío.

Env de mi proyecto (package.json):

{
  "name": "MYAPP",
  "version": "1.0.0",
  "description": "this is front of simula's app",
  "main": "gulpfile.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "build": "browserify ./www/jsx/app.jsx -t babelify -o ./www/js/app.js"
  },

  }
}

Y mi código:

export default class SomeCard extends React.Component {
  constructor(){
    super();

    this.state = {
      data_source: []
    }
  }

  componentDidMount(){
    const {name, data} = this.props.data;
    if(name == 'AAA'){
      let values_a = data.map((tmp_data) =>{
        let date = new Date(tmp_data.date);
        return {
          x: date,
          open: tmp_data.open,
          high: tmp_data.high,
          low: tmp_data.low,
          close: tmp_data.close
        };
      });
      let final_tmp_data = [
        {
          name: name,
          values: values_a
        }
      ];
      console.log(final_tmp_data);  //NOT EMPTY
      this.setState({data_source: final_tmp_data});
      console.log(data_source);     //NOT EMPTY
    }else if(name == 'BBB'){
      let values_b = data.map((tmp_data) => {
        let date = new Date(tmp_data.date);
        let tmp_date = date.getFullYear();
        return {
          "x": String(tmp_date),
          "y": tmp_data.value
        };
      });
      let final_cash_data = [
        {
          "name": name,
          "values": values_b
        }
      ];
      console.log(final_cash_data);          //NOT EMPTY
      this.setState({data_source: final_cash_data});
      console.log(this.state.data_source);   //EMPTY!!!!!!!!
    }
  .....
}

¿¿¿Qué tengo que hacer???
