アプリケーションの p:toolbar が機能しないという苦情が寄せられています。問題が発生したワークステーションの 1 つを個人的に調べたところ、Firefox 49 コンソールに次のエラーがありました。
SyntaxError: missing ) after argument list[Learn More]components.js.jsf:21:18950
components.js を開くと、ファイルが不完全であることがわかりました。次の行で読み込みが停止しました。
PrimeFaces.widget.Menu=PrimeFaces.widget.BaseWidget.extend ...
PrimeFaces のバージョンは 6.0.5 です。
次の 2 つのことを理解したいと思います。
- なぜそれが起こるのか
- 発生した場合、アプリケーション内で修正する方法
1) 私のアプリケーションは一般に公開されていないため、ユーザーが最初に表示するページはログインです。PrimeFaces のバージョンを更新すると、新しいバージョンの components.js のダウンロードがログイン ページでトリガーされますか? 私の推測では、ユーザーが自分の資格情報をブラウザーに保存していて、接続が遅かったため、ログイン フォームを送信したときにページの読み込みさえ完了せず、components.js のダウンロードを中止したと考えられますが、ファイルがローカルに存在するため、ブラウザはそれを使用しようとします。
問題にパターンがあることを考えると (ファイルの読み込みがほぼ途中で停止する)、サーバーの問題でしょうか? Apache TomEE 7.0.1(Tomcat 8.5.3) を使用しています。サーバー ログには、次の例外が数回あります。

2) 少なくとも jQuery がロードされていることを考慮して、次のスクリプトを作成しましたが、破損したキャッシュ ファイルを置き換えません。
<script type="text/javascript">
//<![CDATA[
$(document).ready(function()
{
try
{
var ctx = "#{request.contextPath}";
if(typeof PrimeFaces == 'undefined')
{
$.getScript(ctx + '/javax.faces.resource/core.js.jsf?ln=primefaces')
}
if(typeof PrimeFaces.widget.TriStateCheckbox == 'undefined') // last component on the file
{
$.getScript(ctx + '/javax.faces.resource/components.js.jsf?ln=primefaces')
}
}
catch(e)
{
console.log(e);
}
});
//]]>
</script>
</h:body>
何か案は？
前もって感謝します
