Was würde diese IllegalArgumentException während der Ereignisverteilung verursachen?

Question

Dies ist der Stack-Trace, der erzeugt wird:

Das Seltsame ist, dass die Reihenfolge ich überprüfen und die JCheckBox-es Angelegenheiten deaktivieren. Ich versuche zu sehen, ob es ein Muster gibt, aber ich habe noch nicht genug Daten. Ich versuche nur ein paar Ideen zu bekommen, wo ich nach möglichen Problemen suchen kann.

EDIT 1: Ich habe gerade die vier Methoden in den bearbeiteten Zeilen des Stack-Trace überprüft. Sie werden nur aufgerufen, wenn das Fenster geöffnet wird, um die Felder mit den erforderlichen Daten zu füllen. Sobald der Dialog geöffnet ist, werden sie nie aufgerufen, also sind sie nicht das Problem.

EDIT 2: Nach dreifacher Überprüfung des Zustands jeder Variable in den herausgearbeiteten Funktionsaufrufen habe ich sie als Täter ziemlich eliminiert.

Answer 1

Sie haben anscheinend eine JTable mit einem DoubleRenderer für eine Ihrer Spalten, und die Daten, die Sie erhalten, enthalten ungültige Werte für diese Dezimalspalte. Wahrscheinlich nur einige alphanumerische Zeichen anstelle von Zahlen.
