OpenDolphin で JavaFX アプリケーションを作成したいと考えています。このアプリケーションでは、独自の FXMLController クラスと独自のプレゼンテーション モデルを持つ新しいウィンドウを開きたいと考えています。ダイアログウィンドウを初めて開いたとき、すべてが正常に機能します。ダイアログ ウィンドウを閉じて再度開くと、IllegalArgumentException が発生します。

原因: java.lang.IllegalArgumentException: ID の PM が既に存在します

PM をリセットするか、以前に初期化した PM を再利用するにはどうすればよいですか?

OpenDolphin のルールの 1 つは、プレゼンテーション モデル (PM) が一意の ID を持つことです。同じ ID で 2 番目の PM を作成することはできません。この規則に例外はありません。

その ID で新しい PM を作成するには、まず古いものを削除する必要があります。dolphin.deletePresentationModel(model)その目的のために使用することができます。

2 番目の方法は、PM を削除して再作成するのではなく、存在する場合は再利用することです。

PresentationModel dialogPM = dolphin.findPresentationModelById(model.id);
if (dialogPM == null) {
     dialogPM = dolphin.presentationModel( ... )
}
dialogPM.reset() // if it has been used before, reset all values

これにより、再利用の効率がわずかに向上しますが、そもそも、この PM の属性に関連付けられている可能性があるすべてのリスナーを所定の位置に保持できます。

ハッピーハッキング！
