Warning: setState(...): Can only update a mounted or mounting component.

[pierrecholhot]

When the Geosuggest input is in focus and the react route changes, the following warning pops in the console:

Warning: setState(...): Can only update a mounted or mounting component.
This usually means you called setState() on an unmounted component.
This is a no-op. Please check the code for the Geosuggest component.

Then it points to this part:

/**
 * When the input loses focused
 */
hideSuggests: function hideSuggests() {
  this.props.onBlur();
  setTimeout((function () {
    this.setState({ isSuggestsHidden: true });
  }).bind(this), 100);
},

Not sure if I am supposed to destroy the component somehow in my componentWillUnmount() ?

I suppose we need a check in that setTimeout whether it is still mounted or not.

I'm still getting that warning, it looks like we can't call this.setState in componentWillUnmount here https://github.com/ubilabs/react-geosuggest/blob/master/src/Geosuggest.jsx#L90

This warning can still output in callback of autocomplete service, now at line 190.
