[flexcoders] VerifyError: Error #1053: Illegal override of SeriesEffect in mx.charts.effects.SeriesEffect

[Jim Robson]

Hey guys,

I'm getting the error referenced in the subject line when I place any series
effect anywhere in any application. I get it with SeriesInterpolate,
SeriesSlide, and SeriesZoom tags. I also get it if I try to apply the effect
in ActionScript using the setStyle method of a chart series (e.g. PieSeries,
ColumnSeries) object. In fact, I get the same error even if the series
effect tag is the only thing between <mx:Application> and </mx:Application>!

Anybody else run into this? I'm thinking that either my SDK, or my copy of
Flex Builder, or my copy of Charting, or perhaps my Flash player, is
corrupt. 

Please pass along any info or suggestions you may have. I'm pasting the
complete error message plus a code sample below.

Thanks

===========================

I first ran into the error when trying to use the effect in an app that I'm
building for a customer. When I couldn't get around it, I tried it in
various other apps, but kept getting the same error. I finally copied and
pasted an entire sample app from the docs, and got the same result. Here's
the sample app I used:

<?xml version="1.0"?>

        {item: 3000},
        {item: 2100},
        {item: 3200}
     ]);

     public function addDataItem():void {
        // Add a randomly generated value to the data provider
        var n:Number = Math.random() * 3000;
        var o:Object = {item: n};
        items.addItem(o);
     }
