title: Pass initial value to redux-form
body: <p>I want to pass initial values (coming from the props of a react-redux component) to my redux-form. But, I get not value when I inspect the data passed to the <code>renderField</code> . I followed the posts here in SO and on redux-form git forum, and I'm using <code>initialValues</code> in <code>mapStateToProps</code> but still it doesn't work. </p>
  
  <p>This is my react-redux component which holds the redux-form:</p>
  
  <pre><code>class ShowGroup extends Component {
  
    render() {
      if (this.state.loading) {
        return &lt;div&gt;Loading group ....&lt;/div&gt;;
      }
      if (this.state.error) {
        return &lt;div&gt;{this.state.error}&lt;/div&gt;;
      }
      let group = this.props.groups[this.groupId];
      return (
        &lt;div className="show-group"&gt;
          &lt;form&gt;
            &lt;Field
              name="name"
              fieldType="input"
              type="text"
              component={renderField}
              label="Name"
              validate={validateName}
            /&gt;
          &lt;/form&gt;
        &lt;/div&gt;
      );
    }
  }
  
  function mapStateToProps(state) {
    return {
      groups: state.groups,
      initialValues: {
        name: 'hello'
      }
    };
  }
  
  const mapDispatchToProps = (dispatch) =&gt; {
      return {
               //.....
      };
  };
  
  export default reduxForm({
    form:'ShowGroup'
  })(
    connect(mapStateToProps, mapDispatchToProps)(ShowGroup)
  );
  </code></pre>
  
  <p>This is my renderField code:</p>
  
  <pre><code>export const renderField = function({ input, fieldType, label, type, meta: { touched, error }}) {
    let FieldType = fieldType;
    return (
      &lt;div&gt;
        &lt;label&gt;{label}&lt;/label&gt;
        &lt;div&gt;
          &lt;FieldType {...input} type={type} /&gt;
          {touched &amp;&amp; error &amp;&amp; &lt;span&gt;{error}&lt;/span&gt;}
        &lt;/div&gt;
      &lt;/div&gt;
    );
  }
  </code></pre>
