java.lang.ClassCastException：com.Sun.faces.facelets.compiler.UIInstructionsをorg.primefaces.model.menu.MenuElementにキャストできません

今朝、私は自分のオフィスに入り、最初に目にしたのは、会社のサイトがクラッシュしたことです。私のせいだと思います。

現在、1時間半、これを修正しようとしましたが、何も見つかりませんでした。Webサイトが機能せず、修正できないため（私は一人です。サイトの作成者が行っていないか、休暇中）。だから私はあなたが私を助けることができることを願っています！

私のウェブサイトのdashboard.xhtmlを呼び出すと、この例外が発生します。

Java.lang.ClassCastException: com.Sun.faces.facelets.compiler.UIInstructions cannot be cast to org.primefaces.model.menu.MenuElement

私の問題は、次のとおりです。全体として、私が自分で作成したファイルはどこにもありません。だから私は本当に私のエラーがどこにあるのか本当にわかりません。

手伝って頂けますか？

追加情報は次のとおりです。

エラーメッセージの簡単なグーグルが表示されます

サブメニューにコメントが含まれている場合、PanelMenuをレンダリングできません。 「UIレイアウト初期化エラー...」と書かれたHTML警告ダイアログが表示され、サーバーで例外がスローされます「Java.lang.ClassCastException：com.Sun.faces.facelets.compiler.UIInstructionsを組織にキャストできません.primefaces.model.menu.MenuElement」です。

これをweb.xmlに追加するだけです：

<context-param>
   <param-name>facelets.SKIP_COMMENTS</param-name>
   <param-value>true</param-value>
</context-param>

レンダリング中にJSFのコメントをスキップします。

これをweb.xmlに追加するだけです。

<context-param>
    <param-name>javax.faces.FACELETS_SKIP_COMMENTS</param-name>
    <param-value>true</param-value>
</context-param>

レンダリング中にJSFのコメントをスキップします。

JSF1025以降、facelets.SKIP_COMMENTSは 非推奨 になっています。
