最近、プロジェクトをprimefaces3.3.1から3.4.1にアップグレードしました。レイジーデータモデルを除いて、残りのすべてのプロジェクトは正常に機能しています。追加の変更を加える必要がありますか？

私のxhtmlコード：

これは、3.4での部分的なajaxの動作の変更に関連している可能性があります。以下は、3.4移行ガイドからのものです

partialSubmit is now false by default. It can be globally configured using primefaces.SUBMIT context parameter and components can override the global setting with provided partialSubmit attribute

web.xmlでprimefaces.SUBMITをtrueに設定してみて、これが解決されるかどうかを確認してください。
