Type Error on combination of export and chart.update()

[rstrietzel]

Expected behaviour

The chart can be updated and exported multiple times.

Actual behaviour

After an export followed by an update to deactivate the legend on exports clicking anywhere leads to a Type Error: k.setState is not a function.

It's working fine with Highcharts 4.2.2, therefore probably a regression.

Live demo with steps to reproduce

https://jsfiddle.net/jc74psrt/1/

1. export as png
2. push the button
3. clicking anywhere leads to "TypeError: k.setState is not a function"

Affected browser(s)

Firefox, Chrome

Internal note:
Chart.update didn't exist in v4.2.2.

Observation: We may bypass the error message by checking for button.setState, but the issue then is that the export menu doesn't open the second time, after updating the legend.

Internal note:
I think the problem is with the event closures:

We recreate the exporting button with all events, except the event with hide() for the context menu - we still use old button reference, because menu = chart[cacheName] exists (no destroying in destroyExport(), simple test: chart['cache-highcharts-contextmenu'] = null; - will show the new context menu, still with the error. Number of errors per click will increase, because everytime we add a new event).

In destroyExport() we can try to remove event removeMouseUp ("destroy" event for a chart is not called when updating the chart, right?) instead of addEvent(chart, 'destroy', removeMouseUp);. How does it sound?

Sounds like music to my ears 👍
