奇妙なことに、JCheckBox をチェックしてチェックを外す順序が重要です。パターンがあるかどうかを試していますが、まだ十分なデータがありません。潜在的な問題を探すためにどこに行くべきかについて、いくつかのアイデアを得ようとしています。
編集 1: スタック トレースの編集された行で呼び出された 4 つのメソッドを確認しました。これらは、必要なデータを最初にフィールドに入力するためにウィンドウが開いたときにのみ呼び出されます。ダイアログが開かれると、それらは呼び出されないため、問題はありません。
編集 2: 編集された関数呼び出し内のすべての変数の状態をトリプル チェックした後、私はそれらを犯人としてほとんど排除しました。
