获取＆＃34;无法阅读财产＆attachToForm＆＃39;未定义＆＃34;升级到最新的包后

Question

在升级到formsy-material-ui（0.4.0），formsy-react（0.18.0）和material-ui（0.15.0-beta.1）到最新版本之后，我一直被困住，总是得到{{ 1}}在升级模块之前，一切正常。

尝试了几个没有运气的选项。

发布登录组件代码，该代码将我们带到另一条路线Cannot read property 'attachToForm' of undefined，但在此之前就看到了attachToFrom错误。

我对ReactJS相当新，所以也可以提供任何其他反馈来改进代码（如果有的话）。
