Creating series with effects via Actionscript causes effect to repeat endlessly

Question

Hi,
I've been trying to add effects to programmatically generated series.  I can create everything fine, but when the effect is applied, it repeats over and over.  In the example below, my line series slide on to the chart (that's good), but then disappear and slide onto the chart again, and again, and again.  It should only run the effect once, and then stop.
Any ideas?  The code below reproduces the problem.
thanks for any help,

I am getting the same problem. Can you post if up if you ever find the answer. I will do the same.
The workaround I am using is to put the chart effect (slideIn) on the "showEffect" style as opposed to the "showDataEffect" and start with the series .visible property set to false.  Then when I want to have the series appear with the effect I set the series' .visible property to true.  The data then appears correctly on the chart with the effect.
