Primefaces FileUploadEvent監聽器方法不起作用

現在我正在爲我的應用程序使用Primefacs 3.3.1和JSF 2.0。現在我面臨的一個問題是，即使表單提交，primefaces FileUploadEvent偵聽器也不起作用。我的日誌文件中沒有erorr和異常。但是，它不起作用。我缺少什麼，lib或配置？順便說一句，我使用JBoss 7.1.1應用服務器。Primefaces FileUploadEvent監聽器方法不起作用

刪除Seam並重試。 – BalusC 2013-02-22 11:33:22

@BalusC，如果我刪除了'Seam'，我仍然可以在我的應用程序中使用'Seam'嗎？ – CycDemo 2013-02-22 11:42:13

只是排除一個和其他:)你在那裏有一個Seam多部分過濾器，它表明它也將HTTP請求解析爲'multipart/form-data'。但是一個HTTP請求只能被解析一次。 – BalusC 2013-02-22 11:45:23

您應該禁用接縫多部分過濾器。您應該在components.xml中寫入

web：multipart-filter disabled =「true」/>。對我來說工作得很好。
