Multiple responding graphs and EmberJS = series undefined

Hi,

We are developing an application where multiple Highcharts graphs react to each other, using EmberJS (based on Sproutcore 2.0) . As a little test-case we tried to plot two simple graphs and on a point-click make them switch graph style and re-render. This works fine with Highcharts 2.1.9, but as of 2.2.0 this does not. After clicking on the plotted graphs, it does not re-render but shows an empty graph.

After a closer examination we found that the series object containing the data is somehow undefined after clicking the graph, which is really weird and we can't trace the origin of that 'bug'. Since it works fine with 2.1.9 and stopped working at 2.2.0, I think this is the best place to ask for help.

Check out the jsFiddle for the test-case: http://jsfiddle.net/Bt2xy/7/

The working jsFiddle with Highcharts 2.1.9: http://jsfiddle.net/Bt2xy/11/

NOTE: The jsFiddle will not work in IE 7/8, try adding <script>ENV = { EXTEND_PROTOTYPES: false }</script> after the <body> tag if you are using IE 7/8.

Highcharts 2.2 (and in earlier version of Highstock) removes data from options to free memory (it's useful with large datasets). The simplest solution is to clone the option object, see: http://jsfiddle.net/Bt2xy/12/
