Matt Krokosz commented on FLEX-33169:
-------------------------------------
After pulling my hair out on this one and trying the suggested patch without
much luck on my custom item renderer, I found another solution / work-around
that works very well for me...I hope it works for everyone else too. The
solution was very simple, just set "mouseEnabled" to "false" on all of the
components within your List item. That prevents the mouse up/down events from
targetting those components and creating the problem.

> 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
> Attachments: FLEX-33169_Mobile_List_Selection.patch, ListExt.as

> 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.
