Subject [jira] [Commented] (FLEX-33660) ensureIndexIsVisible() does not work for spark.components.List
Date Mon, 11 Apr 2016 17:35:25 GMT

    [ https://issues.apache.org/jira/browse/FLEX-33660?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15235562#comment-15235562

Philip Keiter commented on FLEX-33660:
--------------------------------------

This custom List component extension worked for me:
<s:List
    xmlns:fx="http://ns.adobe.com/mxml/2009"
    xmlns:s="library://ns.adobe.com/flex/spark"
    valueCommit="callLater(ensureIndexIsVisible, [selectedIndex])">
</s:List>

> The method ensureIndexIsVisible() does not really work, when an item has been added to
a List recently.
> You have to use workarounds like the one described at the http://flexponential.com/2011/02/13/scrolling-to-the-bottom-of-a-spark-list/
> I am attaching a very simple test case ScrollToBottom.mxml which demonstrates the failure
(and the workaround) for Flex 4.10.0.
