React nested route not rendering a component

Question

Could anyone share some light on why this Router configuration doesn't want to render the Project component while trying to access to/design/project/whatever ?

<Route path="/" component={MainWrapper}>
  <Route path="to/design/" component={Design}>
    <Route path="project/:id" component={Project} />
  </Route>
  <Route path="to/code" component={Code} />
</Route>

Thanks for your time!

我只是忘记在Design组件中指定{this.props.children} 。
