AmMaps - Uncaught TypeError: Cannot read property '0' of undefined about amcharts3-react HOT 3 CLOSED

I've done a bit more investigations on this and have narrowed it down a bit.

For the scenario (based on the example code above) where you go from Continent View to Worldview and then try to change the state via the "Change Labels" button the issue is in line 150 of amcharts3-react.js.

It is trying to access a key which the object does not have:

            if (updateArray(obj[key], x, y)) {
              didUpdate = true;
            }

This was easily fixed by checking obj.hasOwnProperty(key)).

The second scenario is in the same area but a different issue. Under the scenario of going from Worldview to Country view and then updating the state the issue arises when setting the key for 'images'. The object is undefined. However it is an array of objects and the comparison on line 144 if (x !== y) is failing. (They are the same). Thus if this check was working correctly then it would never get to call updateArray(obj..).

Hope this helps.
