    <p>I have the list shown below:</p> <pre><code>&lt;s:List id="list2" width="100%" height="100%" dataProvider="{ recordingsShown }" itemRenderer="components.VideoItemRenderer2" selectedIndex="0" visible="false"&gt; &lt;s:layout&gt; &lt;s:TileLayout id="tilelayout" useVirtualLayout="true" orientation="columns" columnAlign="justifyUsingWidth" rowAlign="justifyUsingHeight" requestedColumnCount="3" requestedRowCount="2" paddingBottom="5" paddingLeft="5" paddingRight="5" paddingTop="5" verticalGap="10" horizontalGap="10" /&gt; &lt;/s:layout&gt; &lt;/s:List&gt; </code></pre> <p>which displays in tiles a name, a date and a preview image for each one of the videos contained in the arraycollection recordingsShown given as dataprovider. The problem is when a new video is added,i save the preview pic in a folder and a node describing it in an xml and i put a new item in the arraycollection with </p> <pre><code>recordingsShown.addItemAt(newRecording,0); </code></pre> <p>it is added on stage but the preview image of the last added video is not shown! How can i redraw the whole list in order to show it?</p> <p>Here is my itemRenderer:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;s:ItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" width="400" height="300" autoDrawBackground="true"&gt; &lt;fx:Metadata&gt; [Event(name="playClicked", type="flash.events.Event")] &lt;/fx:Metadata&gt; &lt;fx:Script&gt; &lt;![CDATA[ import flash.filters.GlowFilter; import mx.controls.Alert; import mx.events.FlexEvent; import mx.formatters.DateFormatter; protected function img_rollOverHandler(evt:MouseEvent):void { Image(evt.currentTarget).filters = [new GlowFilter(0xf7941d)]; Image(evt.currentTarget).alpha = 0.9; } protected function img1_rollOutHandler(evt:MouseEvent):void { Image(evt.currentTarget).filters = []; Image(evt.currentTarget).alpha = 1; } protected function playClickHandler(event:MouseEvent):void { dispatchEvent(new Event("playClicked",true,true)); } ]]&gt; &lt;/fx:Script&gt; &lt;fx:Declarations&gt; &lt;s:DateTimeFormatter id="dateTimeFormatter" dateTimePattern="DD.MM.YYYY HH.NN.SS"/&gt; &lt;/fx:Declarations&gt; &lt;s:states&gt; &lt;s:State name="normal" /&gt; &lt;s:State name="hovered" /&gt; &lt;s:State name="selected" /&gt; &lt;/s:states&gt; &lt;s:Rect width="100%" height="100%" radiusX="5" radiusY="5"&gt; &lt;s:filters&gt; &lt;s:DropShadowFilter alpha="0.32" alpha.hovered="0.5" blurX="5" blurY="5" distance="2" /&gt; &lt;/s:filters&gt; &lt;s:fill&gt; &lt;s:LinearGradient rotation="90"&gt; &lt;s:GradientEntry color="0x323232" color.selected="black"/&gt; &lt;s:GradientEntry color="#7f7f7f" color.selected="0x333333"/&gt; &lt;/s:LinearGradient&gt; &lt;/s:fill&gt; &lt;s:stroke&gt; &lt;s:SolidColorStroke color="#ffffff" color.hovered="#f7941d" color.selected="#ed7f09" caps="none" weight="2" joints="miter" miterLimit="4"/&gt; &lt;/s:stroke&gt; &lt;/s:Rect&gt; &lt;s:Label left="10" top="10" fontStyle="italic" fontWeight="bold" color="#f7941d" text="{dateTimeFormatter.format(data.date)}"/&gt; &lt;s:Label left="10" top="25" fontSize="16" fontWeight="bold" color="#ffffff" text="{data.name}"/&gt; &lt;s:Image id="previewImg" left="10" right="10" bottom="10" top="55" scaleMode="stretch" smooth="true" source="http://localhost:5080/thumbs/{data.thumb}" /&gt; &lt;!-- source="assets/img.jpg"/&gt; --&gt; &lt;s:Image source="assets/play.png" rollOver="img_rollOverHandler(event);" rollOut="img1_rollOutHandler(event);" x="136" y="102" click="playClickHandler(event)" complete="this.invalidateSize()"/&gt; &lt;/s:ItemRenderer&gt; </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
