RootRef Error on Menu on routing with react-router-dom

• This is not a v0.x issue.
• I have searched the issues of this repository and believe that this is not a duplicate.

Expected Behavior 🤔

Not to throw error.

Current Behavior 😯

In codesandbox we can’t get the full error details, but locally it’s the stack-trace:

Uncaught Error: Unable to find node on an unmounted component.

React will try to recreate this component tree from scratch using the error boundary you provided, ErrorPage.

Steps to Reproduce 🕹

Link: https://codesandbox.io/s/62y9n1xw7w

1. Click on the AppBar icon button
2. Try navigate to a different page you are in
3. The error is thrown

Context 🔦

I’m trying to use Material-UI together with react-router-dom but can’t make the simplest thing that is navigate to other routes to work.

Your Environment 🌎

Tech	Version
Material-UI	v3.9.1
React	16.7.0
React Router	4.3.1

@DanilloCorvalan This looks like an error with React itself. We are calling ReactDOM.findDOMNode(this) in componentDidUpdate(). There is nothing fundamentally wrong with it. I have managed to simplify a bit the reproduction, but I think that it needs more work before we can send it to React: https://codesandbox.io/s/2om2v1zlz0.

Can you move the AppBar outside the Suspense component?

[jcperez-ch]

I have tried the code sandbox you posted @DanilloCorvalan and I see you use

<Route exact path="/" component={props => <Index {...props} />} />

when you actually need

<Route exact path="/" render={props => <Index {...props} />} />

Lazy components won’t work using the component render, you either need to render them as children or with render prop. Not sure if the issue is going in that direction.
