OK - assuming the "right" way to do this is to call the showDataEffect
functon on the ColumnSet, here's the error message I receive:
TypeError: Error #1009: Cannot access a property or method of a null
object reference.
at mx.charts.effects.effectClasses::SeriesInterpolateInstance/play()
at mx.effects::EffectInstance/startEffect()
at mx.effects.effectClasses::ParallelInstance/play()

The error alert is shown while the app is starting up. I get a different
error when I call the showDataEffect function on the individual
ColumnSeries in the ColumnSets. If that's helpful I can send that as well.
