render never called after a hot reload - how do I debug this

[RobertGary1]

# Expected behavior

The render method should be called after a component is updated. I can see that the source code as been updated but if I put a break point on render() its never called. The DOM does not update correctly.

Could you please try 4.12.12? It might be #1342

[RobertGary1]

No, I'm still seeing it. Oddly I see the console log that its updating. And if I look at the source code in the browser its correctly updated. Its just not calling the render to update the DOM. This was working before, I must have messed up some configuration.

I fixed it In index.js I changed
import {App} from './App';
to
import App from './App';

My guess is that it was loading the class App directly bypassing the default export of
export default hot(module)(App);

So you were using not-warmed App... It should work, but as long as there is no AppContainer around the App - the deep force update was not called, causing your issue.
