>                 Key: FLEX-34212
>                 URL: https://issues.apache.org/jira/browse/FLEX-34212
>             Project: Apache Flex
>          Issue Type: Bug
>          Components: Spark: List, Spark: VerticalLayout
>    Affects Versions: Apache Flex 4.11.0
>            Reporter: Mihai Chira
>              Labels: easytest
>             Fix For: Apache Flex 4.13.0
>
>         Attachments: _invldRTE.fxp
>
>
> Steps to reproduce:
> 1. Import and run the attached project.
> 2. Scroll the list to the bottom.
> Actual result: the RTE below, caused by the perfectly timed MOUSE_WHEEL event.
> Desired result: no RTE, and the list should keep adding items despite the MOUSE_WHEEL
event.
> Notes:
> - four of our users reported this bug within a few months. This means that the odds of
scrolling the list exactly between setting its dataProvider and its commitProperties() function
being called is not so low.
> - s:DataGrid seems to work fine in this scenario.
> RTE:
> Error: invalidIndex
