> Project: Apache Flex
> Issue Type: Bug
> Components: Spark: DataGrid
> Affects Versions: Apache Flex 4.10.0
> Reporter: Micha Pooh

> Fix For: Apache Flex 4.12.0
>
>
> 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)
