[flexcoders] broken: stacked AreaChart when using horizontal DateTimeAxis

[munkydung]

If I create a Stacked AreaChart with a horizontal axis of type
'DateTime', nothing is rendered. However, if I do not specify a
horizontal axis, all is well. Also, if I specify the AreaChart with type
'overlaid' AND use the horizontal DateTime Axis, all is well...
Has anyone else run into this before?

Thanks in advance...

here's a link to a swf (you can view source on it):
