    text
    copied!<p>Ok I have a List with an IconItemRenderer in it. When I set it's dataprovider in AS3 and I begin scrolling, the list is flickering one time (gets white for one frame). This only happens when the messageField/messageFunction is set and there is a different number of lines in the message areas. I'm sure this is a framework bug. Has anyone had the same experience? I would be glad if someone knows a workaround for this. Thanks in advance.</p> <hr> <p>Here's an example code for a view component. Strange to say the flickering seems to take sometimes more, sometimes less time. I tested it on Android and in Desktop mode (adl), error occures on both. The "blabla.." is just to get a string with a random number of lines.</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;s:View xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" title="HomeView"&gt; &lt;s:actionContent&gt; &lt;s:Button label="Set List" click="btn_click(event)"/&gt; &lt;/s:actionContent&gt; &lt;s:List width="100%" height="100%" id="list"&gt; &lt;s:itemRenderer&gt; &lt;fx:Component&gt; &lt;s:IconItemRenderer messageField="text"/&gt; &lt;/fx:Component&gt; &lt;/s:itemRenderer&gt; &lt;/s:List&gt; &lt;fx:Script&gt; &lt;![CDATA[ import mx.collections.ArrayList; protected function btn_click(event:MouseEvent):void { var al:ArrayList = new ArrayList; var obj:Object; var str:String = "blablablablablablablablablablablablablablablablablablablablabblablablablablablablablablablablablablablablablablablablablabblablablablablablablablablablablablablablablablablablablablablablablablablablablablablablablablablablablabla"; for(var i:int = 0; i &lt; 20; i++) { obj = new Object; obj.text = str.substr(0, Math.random()*str.length); al.addItem(obj); } list.dataProvider = al; } ]]&gt; &lt;/fx:Script&gt; &lt;/s:View&gt; </code></pre> <hr> <p>See bug report: <a href="https://issues.apache.org/jira/browse/FLEX-33383" rel="nofollow">https://issues.apache.org/jira/browse/FLEX-33383</a></p> <p>For the workaround see the correct answer below.</p>
