    <p>I am using a List component inside an itemRenderer. The main user interaction involves dragging an item from the List in one renderer and dropping it in another. </p> <p>My problem: When the data object is updated I want the Lists' height to be modified according to the number of objects in the dataprovider(dp), which is passed to the List from the data object. Now I have tried to invalidate the display of the List, refresh its dp and have tried putting this line <code>assets.length &gt; 0 ? assetList.percentHeight = 100 : assetList.height = 10;</code> in other event handlers, such as dragdrop handlers, collection event handlers for the dp etc. I have also tried refreshing the dp for the List component that is using this renderer. The view does eventually get updated but only if I resize the list, or use the scroller or when I begin dragging a new List item but never after the drop.</p> <pre><code>&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" autoDrawBackground="true" width="100%" creationComplete="init()" currentState="collapsed"&gt; &lt;fx:Script&gt; &lt;![CDATA[ [Bindable] private var itemRenderer:ClassFactory; [Bindable] private var colWidth:Number = 100; [Bindable] private var assets:ArrayCollection = new ArrayCollection;; public function init():void{ itemRenderer = new ClassFactory(DefaultRenderer); this.addEventListener(FlexEvent.DATA_CHANGE, onDataChange); } private function onDataChange(e:FlexEvent):void { assets = data.assets; trace(data.name, assets.length); assets.length &gt; 0 ? assetList.percentHeight = 100 : assetList.height = 10; } ]]&gt; &lt;/fx:Script&gt; &lt;s:Group width="100%"&gt; &lt;s:layout&gt; &lt;s:VerticalLayout gap="0" /&gt; &lt;/s:layout&gt; &lt;s:ToggleButton id="viewToggle" label="{data.name}" width="100%" height="50" /&gt; &lt;s:List id="assetList" width="100%" dataProvider="{assets}" height = "10" top="0" left="0" bottom="0" right="0" dragEnabled="true" allowMultipleSelection="true" dragMoveEnabled="true" dropEnabled="true" itemRenderer="{itemRenderer}" &gt; &lt;s:layout&gt; &lt;s:TileLayout requestedColumnCount="2" horizontalGap="0" verticalGap="0" columnWidth="{colWidth}" rowHeight="{colWidth}"/&gt; &lt;/s:layout&gt; &lt;/s:List&gt; &lt;/s:Group&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.
