[flexcoders] Problems with showDataEffect trigger looping on Chart Seris in Flex 3

[mgrayfmr]

Has anyone run into this issue in Flex 3?
The showDataEffect is looping endlessly, causing a transtion to run 
over and over again.

I have two charts, one a LineChart and one a ColumnChart.
On the series of each, I have set the 
showDataEffect="{nameOfEffectHere}"
For the LineChart, the effect is declared as:

<mx:WipeRight
  id="seriesWipeIn"
  duration="2500"
  repeatCount="1"               
  scaleEasingFunction="mx.effects.easing.Circular.easeInOut"/>

For the ColumnChart, it is declared as:
<mx:SeriesSlide
  id='effEaseUp' 
  direction="up"
  repeatCount="1"
  easingFunction="mx.effects.easing.Bounce.easeInOut"
  duration="1200"/>

In both cases, the effect loops.
I cannot find what is causing the showDataEffect to be triggered.
This code worked fine in Flex 2.0, but breaks in Flex 3.0.

Any info would be appreciated!!!
