Chart View Bug in Jewel

I am trying to add a column chart to a jewel project based on the code in the StatsView.mxml example. I have js:ColumnChart in a j:Card and the browser throws the following error... what am I doing wrong?

`Uncaught TypeError: Cannot set property 'x' of null

Start with the StatsView.mxml example and compare its js:ColumnChart usage with the chart placed inside a j:Card. Reproduce the browser error and inspect ChartView.js at line 127, then verify that the column chart renders without the null-property exception.
