hotRenderWithHooks dose not provide context (?)

[Bnaya]

getting TypeError: Cannot read property 'muiFormControl' of undefined

stack.type points to FormLabel is part of MUI 1.x, that expects getting context,
But the function call supplies only props.

react-hot-loader@4.11.1

react-dom@npm:@hot-loader/react-dom@16.8.6

BTW without patching react-dom, it works.

React 15 legacy :(
Patching react-dom activates configuration option ignoreSFCWhenInjected, so RHL stop wrapping FC with anything. And that anything was a Class component for FCs with a legacy context (cos it's not easy to track it, so we used Class-based wrapper to track context value).

How to fix

1. setConfig({ignoreSFCWhenInjected: false}) - it will fix hot comparison render when react-dom is patched
2. setConfig({disableHotRendererWhenInjected: true}); - to disable buggy hotReplacementRender, and be happy ever after.

v4.12 comes with disableHotRendererWhenInjected set to true by default.

Can you elaborate a bit what we "lose" when disableHotRendererWhenInjected: true?

[theKashey]

Nothing. Except some bugs like you faced, plus some problems with libraries with use React.readContext method directly.
