React router v4 not working with Redux

Question

Developing a React application using React router v4. All worked well until I introduced Redux in my app. Since then on click of links to change route the browser url changes but the component corresponding to the route is not getting loaded. It works well if I comment out Redux code. What could be causing this? Here is my code for routing:

import React, { Component } from 'react';
import { Switch, Route, Link } from 'react-router-dom';
import LeftSubDefault from './../components/left-sub-default.component';
import LeftSubOne from './../components/left-sub-one.component';
import LeftSubTwo from './../components/left-sub-two.component';
import { withRouter } from 'react-router-dom';
import { connect } from "react-redux";
import { goToLeftDefault, goToLeftOne, goToLeftTwo } from "./../actions/leftRouteActions.js";

class LeftComponent extends Component {
  render() {
    return (
      <div className="col-xs-6">
          <p>
            Current sub route: {this.props.currentRoute}
          </p>
          <ul>
            <li onClick={this.props.goToDefault}><Link to={'/'}>Go To Default</Link></li>
            <li onClick={this.props.goToSub1}><Link to={'/left-sub1'}>Go To One</Link></li>
            <li onClick={this.props.goToSub2}><Link to={'/left-sub2'}>Go To Two</Link></li>
          </ul>
          <Switch>
            <Route exact path='/' component={LeftSubDefault} />
            <Route exact path='/left-sub1' component={LeftSubOne} />
            <Route exact path='/left-sub2' component={LeftSubTwo} />
          </Switch>
      </div>
    );
  }
}
const mapStateToProps = (store) => {
  return {
    currentRoute: store.routes.currentRoute
  };
}
const mapDispatchToProps = (dispatch) => {
  return {
    goToDefault: () => {
      dispatch(goToLeftDefault())
    },
    goToSub1: () => {
      dispatch(goToLeftOne())
    },
    goToSub2: () => {
      dispatch(goToLeftTwo())
    }
  };
}
export default withRouter(connect(mapStateToProps, mapDispatchToProps)(LeftComponent));

PS: I get no error in console. The code runs clean just components don't load. Here is a similar thread on github: 4671. I have seen lot of threads on various sites but none has the solution for this issue.

Hah, now I'm making a project with react-router and redux too =).

Look at the official documentation about redux integration https://reacttraining.com/react-router/web/guides/redux-integration.

I think the main point is order of withRouter and connect Hocs.

The problem is that Redux implements shouldComponentUpdate and there’s no indication that anything has changed if it isn’t receiving props from the router. This is straightforward to fix. Find where you connect your component and wrap it in withRouter.

From the official docs.

UPD

import { withRouter } from 'react-router-dom';
import { connect } from 'react-redux';

class Home extends React.Component {...}

export default withRouter(
    connect(mapStateToPropsFunc)(Home)
);
