>             Project: Apache Flex
>          Issue Type: Bug
>          Components: Spark: DataGrid
>    Affects Versions: Apache Flex 4.11.0, Apache Flex 4.12.0, Apache Flex 4.13.0
>         Environment: Windows 7 - from inspection, probably system independent
>            Reporter: Bill Turner

> A Spark DataGrid with locked column will throw an "Index out of bounds" exception if the ArrayCollection dataProvider's filter function reduces the number of elements displayed.
> The DataGrid correctly handles the change of source data if there are no locked columns, or if the dataProvider itself is changed to the new collection.
