データベースからポイントを取得してオーバーレイに追加するマネージド Bean があります。同じマネージド Bean で、データベースから関連データを取得し、ユーザーが任意のマーカーをクリックするとそれらを表示します。
ここまでは問題ありません。私の管理対象 Bean は@SessionScoped. ただし、プロジェクトをシステムに追加しようとすると、追加されますが、以前のバージョンのデータが表示されます。@ViewScoped要求に応じてデータを取得するように変更すると、基本的に最後に更新された状態でデータを取得します。
ここに私の豆があります：

ご覧のとおり、マーカーをクリックすると、データがタブに表示されます。使用する@SessionBeanとすべてのタブがいっぱいになりますが、現在のセッションでデータベースから最後の更新を取得しません。
使用する@ViewScopedと、最後の更新が認識されますが、最初のタブしか表示されません。他は空です。
どうすればこれを達成できますか？どんな助けでも大いに感謝します。
