我有一個實體Bean和它對應的ActionScript類時，我傳遞的是類的一個對象，我得到這個錯誤：GraniteDS無法從動作類轉換爲Java bean ...如何解決這個問題？

請任何幫助？在此先感謝:)
如果我不得不猜測，自定義命名空間「元」是問題。但是，由於您的AS3類沒有公共變量，你到底希望轉移什麼？通常，AMF對象轉換隻是將一個對象上的公共屬性從一端傳遞到另一端。 – JeffryHouser 2011-03-19 16:59:29
看起來它可能是您在其中一個列表中獲得的對象之一。看起來解串器已經降低了幾個級別。您在集合中獲得的所有對象是否可以serialisable？ – 2011-03-19 17:07:32
