findDOMNode(this) returns null in _animateCircle()

[easadler]

In VoroniCircleContainer.jsx in the linechart folder, findDOMNode is returning null, which is messing up the animation.

 _animateCircle() {
    const rect = findDOMNode(this).getElementsByTagName('circle')[0].getBoundingClientRect(); //here
    this.props.onMouseOver.call(this, rect.right, rect.top, this.props.dataPoint);
    this.setState({
      circleRadius: this.props.circleRadius * (5 / 4),
      circleFill: shade(this.props.circleFill, 0.2),
    });
  }

I haven't been able to diagnose the issue, but it appears to be passed to a child component, which could be confusing react for some reason or another. Any idea what is wrong?

I don't have a problem with my npm installed rd3, but am having it with the cloned version from this repo.

    let handleMouseOver;
    let handleMouseLeave;
    if (props.hoverAnimation) {
      handleMouseOver = this._animateCircle; // here
      handleMouseLeave = this._restoreCircle;
    } else {
      handleMouseOver = handleMouseLeave = null;
    }

    return (
      <g>
        <VoronoiCircle
          handleMouseOver={handleMouseOver} //here
          handleMouseLeave={handleMouseLeave}
          voronoiPath={this._drawPath(props.vnode)}
          cx={props.cx}
          cy={props.cy}
          circleRadius={this.state.circleRadius}
          circleFill={this.state.circleFill}
        />
      </g>
    );

Oh? This is weird. https://github.com/yang-wei/rd3/tree/master/src/linechart do not has any new commit since the last release.

Can you show me the step you reproduce this bug ?
