>             Project: Apache Flex
>          Issue Type: Bug
>          Components: Spark: DataGrid
>    Affects Versions: Apache Flex 4.10.0
>            Reporter: Micha Pooh
>
> Try to drop an item to a spark:DataGrid witch has no data (empty dataProvider). The application throws an error (out of range 1)
> This happens because the calculation for the dropIndex is false
> (returns 1 - should be 0)
> It seems that this happens because the Grid Skin returns also 1 for his numElements property .
> (see grid.layout.calculateDropLocation(event) in the DataGrids calculateDropLocation)
