Help with material-ui leftNav,react-router and redux

I am having trouble getting this to work. I'm trying to get the material ui leftNav to work with react router and redux with nav going through the store and router. This was close, but didn't get all the way to the menu item.

TypeError: Cannot read property 'isActive' of undefined

I was also referring to these examples: https://github.com/callemall/material-ui/blob/master/docs/src/app/components/app-left-nav.jsx

http://codetheory.in/react-integrating-routing-to-material-uis-left-nav-or-other-components/

Here is the component I'm working on. I started with react-redux-universal-hot-example. This component is going into the App component.

import React, { Component } from 'react';
import LeftNav from 'material-ui/lib/left-nav';
import RaisedButton from 'material-ui/lib/raised-button';

const menuItems = [
  { route: '/widgets', text: 'Widgets' },
  { route: 'survey', text: 'Survey' },
  { route: 'about', text: 'About' }
];

export default class MaterialLeftNav extends Component {
  static propTypes = {
    history: React.PropTypes.object
  }

  static contextTypes = {
    location: React.PropTypes.object,
    history: React.PropTypes.object
  }

  contructor(props) {
    super(props);
  }

  _onLeftNavChange(e, key, payload) {
    this.props.history.pushState(null, payload.route);
  }

  _handleTouchTap() {
    this.refs.leftNav.toggle();
  }

  _getSelectedIndex() {
    let currentItem;

    for (let i = menuItems.length - 1; i >= 0; i--) {
      currentItem = menuItems[i];
      if (currentItem.route && this.props.history.isActive(currentItem.route)) return i;
    }
  }

  render() {
    return (
      <div>
        <LeftNav
          ref="leftNav"
          docked
          menuItems={menuItems}
          selectedIndex={this._getSelectedIndex()}
          onChange={this._onLeftNavChange}
        />
        <RaisedButton label="Toggle Menu" primary onTouchTap={this._handleTouchTap} />
      </div>
    );
  }

}

  1. You can just initialise the tap event plugin directly:
    require("react-tap-event-plugin")()
  2. If your app has no state you do not need to wrap it in a component. A normal function will do.
    So you can write your App component like this:
import React from 'react';

const App = () => (
  <div>
    <Navigation />
     {this.props.children}
  </div>
)

export default App
