I want to pass initial values (ing from the props of a react-redux ponent) to my redux-form. But, I get not value when I inspect the data passed to the renderField . I followed the posts here in SO and on redux-form git forum, and I'm using initialValues in mapStateToProps but still it doesn't work.

This is my react-redux ponent which holds the redux-form:

class ShowGroup extends Component {

  render() {
    if (this.state.loading) {
      return <div>Loading group ....</div>;
    }
    if (this.state.error) {
      return <div>{this.state.error}</div>;
    }
    let group = this.props.groups[this.groupId];
    return (
      <div className="show-group">
        <form>
          <Field
            name="name"
            fieldType="input"
            type="text"
            ponent={renderField}
            label="Name"
            validate={validateName}
          />
        </form>
      </div>
    );
  }
}

function mapStateToProps(state) {
  return {
    groups: state.groups,
    initialValues: {
      name: 'hello'
    }
  };
}

const mapDispatchToProps = (dispatch) => {
    return {
             //.....
    };
};

export default reduxForm({
  form:'ShowGroup'
})(
  connect(mapStateToProps, mapDispatchToProps)(ShowGroup)
);

This is my renderField code:

export const renderField = function({ input, fieldType, label, type, meta: { touched, error }}) {
  let FieldType = fieldType;
  return (
    <div>
      <label>{label}</label>
      <div>
        <FieldType {...input} type={type} />
        {touched && error && <span>{error}</span>}
      </div>
    </div>
  );
}

      </div>
    </div>
  );
}

You are exporting the wrapped ponent with incorrect order

export default reduxForm({
  form:'ShowGroup'
})(
  connect(mapStateToProps, mapDispatchToProps)(ShowGroup)
);

should be

export default connect(mapStateToProps, mapDispatchToProps)(reduxForm({
  form:'ShowGroup'
})(ShowGroup);

The reason being that the redux form HOC needs the initialValues prop for itself, if you reverse the order, reduxForm doesn't get the props rather they are passed directly to the ponent, which doesn't know what to do with it.
