> Key: FLEX-33315
> URL: https://issues.apache.org/jira/browse/FLEX-33315
> Project: Apache Flex
> Issue Type: Bug
> Components: Advanced Data Grid
> Affects Versions: Adobe Flex SDK 4.6 (Release)
> Environment: ALL
> Reporter: Ryan
> Assignee: Justin Mclean
> Fix For: Apache Flex 4.10.0
>
> Attachments: testProj.mxml
>
>
> Setting AdvancedDataGrid's selectedItems to [] in the grid's creation
> complete handler causes it to never update it's selected items array (if the
> dataprovider is initially empty).
>
> Expected: selectedItems has the selectedItems that are visually represented
> by the grid.
> Results: selectedItems is always empty.
