當我使用Flex SDK 4.0或4.1編譯Flex項目時，沒有任何問題。但是當我切換到SDK 4.5（因爲我們的團隊開始使用Flash Builder 4.5），我在打開一個窗口（彈出一個窗口小部件窗口）時出錯。我在網上搜索了幾天，但仍然不知道是什麼導致了這個問題。Flex ArgumentError：Error＃2015：Invalid BitmapData
請幫忙。
以下是錯誤消息：
ArgumentError: Error #2015: Invalid BitmapData.

-------------------- ------------------------- 謝謝。我有皮膚。問題在於它與SDK 4.1協同工作的原因，而不是SDK 4.5。 這裏是皮膚的定義：

感謝。不幸的是，它不起作用。 但是你是對的，交叉淡入淡出效果導致了這個問題。我刪除了下面的代碼片段，它的工作原理。
<s:transitions>
<s:Transition autoReverse="true">
<s:CrossFade target="{holder}"/>
</s:Transition>
</s:transitions>
任何想法。請幫忙。
你的RefreshButton皮膚中有圖像嗎？如果是這樣，我認爲皮膚代碼可能更有用 – Exort
