error: popup pie chart and locate widget conflict

Hello,

this seems like a strange observation so I'm wondering if anyone else has encountered this.

I'm using arcgis viewer for flex and consuming a web map from ArcGIS online.

I have a popup configured using ArcGIS online that shows a pie chart. I've noticed that in my application if I search for an address or two using the locate widget, and move around a bit, the pie chart graphic seems to get stuck, it shows the wrong data.

here's the app

any ideas ? thanks in advance
