piotrzarzycki21 commented on issue #639: Binding doesn't work in Jewel List item renderers using VO URL: https://github.com/apache/royale-asjs/issues/639#issuecomment-568587564 I have made interesting observation. In our project I'm using following workaround to have it working: ``` <?xml version="1.0" encoding="utf-8"?> <j:ListItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009"; xmlns:j="library://ns.apache.org/royale/jewel" xmlns:js="library://ns.apache.org/royale/basic"> <fx:Script> <![CDATA[ [Bindable("dataChange")] public function get someVO():SomeVO { return data as SomeVO; } override public function set data(value:Object):void { if (super.data != value && super.data) { super.data.removeEventListener(ValueChangeEvent.VALUE_CHANGE, onDataChange); } super.data = value; if (super.data) { super.data.addEventListener(ValueChangeEvent.VALUE_CHANGE, onDataChange); } } private function onDataChange(event:ValueChangeEvent):void { itemQuantity.text = String(someVO.itemQuantity); } ]]> </fx:Script> <j:beads> <js:ItemRendererDataBinding /> </j:beads> <j:HGroup percentWidth="100" percentHeight="100" itemsHorizontalAlign="itemsCentered" itemsVerticalAlign="itemsCentered"> <j:Label localId="itemQuantity" text="{someVO.itemQuantity}" percentWidth="100"/> </j:HGroup> </j:ListItemRenderer> ``` If my VO has `[Bindable]` on top of it `ValueChangeEvent.VALUE_CHANGE` is not being dispatched, so listener `onDataChange `is not called. ``` [Bindable] public class SomeVO { } ``` If VO has `[Bindable]` on top on every property everything is working fine and `onDataChange` has been called. ``` public class SomeVO { public function SomeVO() { } private var _itemQuantity:int = 1; [Bindable] public function get itemQuantity():int { return _itemQuantity; } public function set itemQuantity(value:int):void { _itemQuantity = value; } } ``` Note that this change on VO won't fix original issue - I checked that.
