Ryan Frishberg commented on FLEX-33169:
---------------------------------------
Do you see List.item_mouseDownHandler() being called at all? You could also
take a look at InteractionStateDetector.mouseEventHandler() (which is what the
item renderer uses to determine whether it's in down or hovered state) to see
if there's an issue in there. I'm just curious what mouse events you're seeing
and whether it is indeed an AIR issue (for not firing the right mouse events)
or a Flex issue for not interpretting the mouse events correctly.

> 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.
