Question

我只是从Flex 4.5升级到Flex 4.6，该应用程序与Flex 4.5完美配合，但在Flex 4.6中运行时仍然出现错误。

这就是抛出错误，loginPopup是一个SkinnablePopupContainer

protected function init(event:FlexEvent):void
{
    loginPopup = new LoginPopup();      
    loginPopup.currentState = "Start";
    loginPopup.open(UIComponent(FlexGlobals.topLevelApplication),true); -- This line throws the error
}

错误是：

[SWF] TDMAPP.swf - 7,212,792 bytes after decompression

有谁知道如何解决这个问题？

Answer 1

通过将这些代码放在APPLICATION_COMPLETE事件而不是视图的CREATION_COMPLETE事件中解决了这个问题。看起来Flex 4.6中的创建顺序有点不同

希望有所帮助。
