v4.4.4 appears to prevent components from receiving context changes

I have a project based on https://github.com/erikras/react-redux-universal-hot-example and one of my components needs to check router.isActive(someUrl) whenever a route changes and update its style/markup. The router object is accessible from components via context. Since react-redux v4.4.4 the component no longer updates (render, shouldComponentUpdate, componentWillReceiveProps are not called) on route change.

I’ve specifically checked that it works with <= v4.4.3 and not with >= v4.4.4.

The essential code of the component is:

class Item extends Component {
  static contextTypes = {
    router: PropTypes.object
  };

  render() {
    return (
      <div>{this.context.router.isActive(this.props.url) ? 'yes' : 'no'}</div>
    );
  }
}

@landabaso React Redux only uses context for dependency injection of the store. The future updates work because Child subscribes to the store directly via store.subscribe() API.

@krukid I sent a few PRs to fix this in React Router, and it won’t be an issue in 3.0 anymore.

Sorry but 2.4.0 had no relation to this issue. withRouter that was added there just exposes context as a prop but it doesn’t affect how that context is actually updated.

https://github.com/reactjs/react-router/issues/470 is still open. This is the issue you want to be tracking.

I documented a workaround above. Please don’t “suffer”, just use { pure: false } in the meantime. This is exactly why it was added.
