  1. POFlex: Why does mouseOut of a DataGroup ItemRenderer cause a state change?
    text
    copied!<p>I've found a very annoying problem with the itemRenderers in a DataGroup in flex 4, when I mouseout of the itemRenderer is returns to its default state. Here's an example:</p> <pre><code>&lt;s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx"&gt; &lt;s:BorderContainer&gt; &lt;s:DataGroup&gt; &lt;s:layout&gt; &lt;s:VerticalLayout gap="1"/&gt; &lt;/s:layout&gt; &lt;s:dataProvider&gt; &lt;s:ArrayCollection&gt; &lt;fx:Object title="One" /&gt; &lt;fx:Object title="Two" /&gt; &lt;fx:Object title="Three" /&gt; &lt;/s:ArrayCollection&gt; &lt;/s:dataProvider&gt; &lt;s:itemRenderer&gt; &lt;fx:Component&gt; &lt;s:ItemRenderer&gt; &lt;s:states&gt; &lt;s:State name="expanded" /&gt; &lt;s:State name="collapsed" /&gt; &lt;/s:states&gt; &lt;fx:Script&gt; &lt;![CDATA[ private function expandCollapse():void { currentState = (currentState == "collapsed") ? "expanded" : "collapsed"; } ]]&gt; &lt;/fx:Script&gt; &lt;s:VGroup&gt; &lt;mx:Button click="expandCollapse();" label="Click me to hide the number" /&gt; &lt;s:SkinnableContainer&gt; &lt;s:VGroup height="0" height.expanded="NaN"&gt; &lt;s:Label text="{data.title}" /&gt; &lt;/s:VGroup&gt; &lt;/s:SkinnableContainer&gt; &lt;/s:VGroup&gt; &lt;/s:ItemRenderer&gt; &lt;/fx:Component&gt; &lt;/s:itemRenderer&gt; &lt;/s:DataGroup&gt; &lt;/s:BorderContainer&gt; &lt;/s:Application&gt; </code></pre> <p>When the user clicks on the button the VGroup is collapsed as expected, but then if a user moves their mouse out of the item renderer it then collapses, i.e. returns to its default state.</p> <p>Is this a bug or am I missing something here?</p> <p>Cheers,</p> <p>Chris</p>
