组件重新渲染时触发的flex事件？

Question

creationComplete每次渲染组件时,会发生什么类似的调用？我想在每次呈现组件时重新运行一个函数(它必须发出HTTP请求,但它每次调用的url都会更改),我无法弄清楚如何执行它.

对于上下文:

<s:Group 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="100%" height="100%"
     creationComplete="loadGallery()">

private function loadGallery():void {
            var src:String = "http://localhost:3000/car_type/" + UserPreference.getInstance().carType.toString() + ".xml";
            Alert.show(src);
            httpService.url = src;
            httpService.send();
        }

Answer 1

而不是creationComplete使用updateComplete.
