此問題主要針對PrimeFaces dev團隊，但也許其他人知道解決方法。我無法在PrimeFaces支持論壇上傳截圖，但我可以在這裏鏈接到我的問題。PrimeFaces 3.0 - 需要修復或解決<p:calendar>'添加6年'缺陷
報告爲PrimeFaces問題跟蹤器中的缺陷。添加明星投你的票了PrimeFaces開發團隊解決這個問題：link to defect in their issue tracker
在PrimeFaces支持論壇討論here。
仍然存在於PrimeFaces 3.0-M3-SNAPSHOT
問題：
我使用PrimeFaces 3.0 <p:calendar>控制，以允許用戶查看和編輯同時包含Date對象日期和時間。 JavaScript控件似乎存在一些缺陷，導致它在+6年附近某個地方添加了一些奇怪的偏移量。
我已經設置了一些代碼來演示這個問題。
在第一個<p:calendar>我使用最初爲空的託管bean Date。控制是可以的。它將打開並將初始值設置爲當前日期，並將小時/分鐘/秒置零。我可以使用滑塊來正常設置小時，分鐘和秒鐘。
在第二<p:calendar>我使用託管bean Date最初被設定爲new Date()。這將創建一個新的Date對象設置爲當前服務器時間。控制是不是好吧。雖然<p:calendar>框中顯示的日期/時間最初看起來是正確的，但在將來打開JavaScript選擇器控件時，它將被修改爲一些奇怪的值。在關閉選擇器控件時，託管bean上的日期被設置爲奇怪的值。
，可能會或可能不相關的另一個問題是，當我嘗試使用自定義format的日期：
ddHHmm'Z'MMMyy
此格式由我的客戶在其域中使用，我需要支持我不知何故。當我嘗試點擊框時，JavaScript選擇器甚至不會打開。有關該模式的東西（在Java SimpleDateFormat中工作得很好）將其分解。 PrimeFaces文檔對此進行了說明。
問：有沒有人對這些問題<p:calendar>任何解決方法嗎？
