以下代码适用于Dartium,但在最近的Firefox和Edge中引发了异常:

version: '2'
services:
 hadoop:
  image: hadoop:2.6
 flume:
 image: flume:last
 links:
 - hadoop

其中initPolymer().then((Zone z) { (document.getElementById("fooDialog") as PolymerElement) .set("opened", true); }); 是文档正文中的自定义聚合物元素。来自例外的消息:

fooDialog

当我将其重写为:

时,问题就消失了
Casting value of type HtmlElement to incompatible type PolymerElement

所以我猜我早点打电话给initPolymer().then((Zone z) { new Future.delayed(new Duration(seconds: 5), () { (document.getElementById("fooDialog") as PolymerElement) .set("opened", true); }); }); 。我怎么知道聚合物在最近的dc聚合物rc中完全初始化(dart sdk 1.15.0,聚合物1.0.0-rc.16)?
