在p：accordianpanel選項卡中的表單不會生成驗證消息，但命令按鈕的作用不然

Question

我在p：accordionpanel的選項卡中有一個表單，所以每個選項卡都有自己的形式和commandbutton。命令按鈕工作正常，但不顯示p：消息。如果驗證失敗，數據不會存儲在數據庫中，我只是不會收到消息。

支持bean是會話作用域。

模板中沒有任何表單，所以沒有表單嵌套在另一個表單中。我試圖在命令按鈕中添加f：ajax render =「messages」，正如BalusC在他十分讚賞的11個問題中所建議的，以詢問命令按鈕是否失敗，但之後commandbutton不再工作。

感謝您的幫助！

添加更新= 「@父」 爲P：的commandButton解決了這個問題。

感謝BalusC關於更新屬性的提示。

我使用PrimeFaces 3.4.2
