strutsでサブミットした後にフォームデータをリセットする

Question

私はstrutsを使い慣れていないし、アプリケーションがstrutsを使用していて、フォームを送信するたびに古い値が送信され、または私は別のタブに移動して同じタブに戻ってきて、この場合は値がリセットされています。

私のシナリオでは、once.onで実行した後にいくつかの値をリセットする私がこの値を削除しなければ、私はいくつかのデータを検索してフォーム上に表示しなければならないそれらの値に基づいています。

これは私のexecuteメソッドです：私は、実行後に "terminalSearchByTid" フィールドをリセットする必要が
