[jira] [Comment Edited] (FLEX-34819) DataGrid with locked columns throws exception if dataProvider filter function shrinks values

After building the app:
* Lock Col toggles locking/unlocking of the first column
* Filter will set the filter on the ArrayCollection data provider
* Change creates a new data provider with a subset of the data
* Reset gets back to ground zero.

Everything works OK for both Filter and Change if the column isn't locked.
If the column is locked, Change works, but Filter throws an "index out of bounds" error

> 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.
