Error message show up if I add following line to onItemRollOut function.
findGraphicByAttribute(event.itemRenderer.data.oid).symbol = resultsSymbol;

Do you know any other way try to highlight polygon on datagrid when item roll over?

Thank you.

May Jeff,

Is the item renderer null? Your a developer right? You should be able to debug what item is null.
