Subject [jira] [Commented] (FLEX-33169) Spark List selection on mobile doesn't work properly
Date Wed, 10 Apr 2013 01:17:13 GMT

    [ https://issues.apache.org/jira/browse/FLEX-33169?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13627343#comment-13627343

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.

>             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

> 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.
