> Key: FLEX-33169
> URL: https://issues.apache.org/jira/browse/FLEX-33169
> Project: Apache Flex
> Issue Type: Bug
> Components: Spark: List
> Affects Versions: Adobe Flex SDK 4.5.1 (Release), Adobe Flex SDK 4.6
> (Release)
> Environment: iOS 5.x, Android 3.2/4.0, Air 3.0 - 3.3
> Reporter: Al Birdy
>
> The touch selection of list items on the actual device does not work properly.
> Sometimes, even though the touch has definitely been recognized by the
> device, the list selection change isn't committed, instead the previously
> selected item remains selected.
> To reproduce the issue, please set up a new Flex mobile project and add the
> most basic list with inline renderer to a view:
> <s:List id="myList" width="100%" height="100%">
> <s:dataProvider>
> <s:ArrayCollection>
> <fx:Object label="Item1" />
> .....
> <fx:Object label="Item30" />
> </s:ArrayCollection>
> </s:dataProvider>
> </s:List>
> Deploy the app to an actual device (this bug does NOT appear in the
> emulator!) and randomly try to select items, scroll the list, select again
> and so on. You'll notice that the down color is sometimes set, but the
> selection isn't changed.
