ReferenceError: calledOnce is not defined

See original GitHub issue

When used with react-hot-loader it throws this error

VM37389:13 Uncaught ReferenceError: calledOnce is not defined
    at ProxyComponent.result [as getDateFilterMinDateRefinement] (eval at __reactstandin__regenerateByEval (VM36190 CourseSearch.js:NaN), <anonymous>:13:5)

getDateFilterMinDateRefinement() is a function that’s wrapped in memoize().

The error happens, for example, when the component containing memoization is removed from code and then hit “Save” so that it hot-reloads.

@alexreardon thanks for the context, it’s really helpful, I can confirm the error is gone after upgrade react-hot-loader to ^4.3.0, but seems the memoized function won’t be reloaded any more, but that’s not the problem of this library (UPDATE: that’s intended https://github.com/gaearon/react-hot-loader/pull/1002)

Thanks for your great library 👍 , I think it’s good to close now, but change the label to question in case the others meet the same problem

Right now I have to workaround like this this.method = module.hot ? this.method : memoize(this.method)
