たとえば、ファセットに、Bean内の10個の異なるフィールドに値式でバインドされた10個の出力テキストがあるとします。最初のゲッターを呼び出すときに例外が発生した場合でも、次の9を呼び出す必要がありますか？
これは、これをテストするときに私が見ている動作だからです。これは、JSF2を使用するようにブーストされたレガシーモジュールで重大な問題を引き起こします。
私はMojarra2.1.16を使用していて、Mojarra2.1.6で試しました。溶接BeanとJSF2Beanの両方で試してみました。コンテナはTomcat7です。
この動作を何らかの方法で変更できますか？これが望ましい行動だとは想像できません。
以下でそれを再現するために使用したコード：
