>    Affects Versions: Adobe Flex SDK 4.6 (Release)
>         Environment: ALL
>            Reporter: Ryan

> Setting AdvancedDataGrid's selectedItems to [] in the grid's creation complete handler causes it to never update it's selected items array (if the dataprovider is initially empty).
>   
> Expected:   selectedItems has the selectedItems that are visually represented by the grid.
> Results:  selectedItems is always empty.
