Flash Flex ArgumentError:错误#2015:位图数据无效

当我用Flex SDK 4.0或4.1编写Flex项目时，没有问题。但当我切换到SDK 4.5时（因为我们的团队开始使用flash builder 4.5），我在打开窗口（弹出窗口小部件）时出错。我在网上搜索了几天，但仍然不知道是什么导致了这个问题

请帮忙

以下是错误消息：

------------------------------------ 谢谢我有皮肤。问题是为什么它与SDK 4.1一起工作，而不是与SDK 4.5一起工作。 以下是皮肤的定义：

谢谢。不幸的是，它不起作用。 但是你是对的，交叉淡入淡出效应导致了这个问题

<s:transitions>
    <s:Transition autoReverse="true">
        <s:CrossFade target="{holder}"/>
    </s:Transition>
</s:transitions>

---

任何想法。请帮忙

从堆栈跟踪来看，交叉淡入效果似乎是问题所在。请尝试以下方法：

<s:Group id="holder">
    <s:BitmapImage source="@Embed('../../assets/images/GenericRefresh16.png')"
                   visible.over="false" />
    <s:BitmapImage source="@Embed('../../assets/images/GenericRefresh16_active.png')"
                   visible.over="true" />
</s:Group>

<s:transitions>
    <s:Transition autoReverse="true">
        <s:CrossFade target="{holder}"/>
    </s:Transition>
</s:transitions>

您的皮肤中有图像吗？如果是这样，我认为皮肤代码可能会更有用**我只被允许在我的帖子中添加评论。我在原始帖子中添加了代码。
