Qu'est-ce qui provoquerait cette exception IllegalArgumentException lors de l'envoi d'un événement?

Question

C'est la trace de la pile qui est générée:

La chose étrange est que l'ordre que je cocher et décocher les questions JCheckBox-es. J'essaie de voir s'il y a un modèle, mais je n'ai pas encore assez de données. J'essaie juste d'avoir des idées sur où aller chercher des problèmes potentiels.

EDIT 1: Je viens de vérifier les quatre méthodes appelées dans les lignes éditées de la trace de la pile. Ils ne sont appelés que lorsque la fenêtre s'ouvre pour remplir initialement les champs avec les données requises. Une fois le dialogue ouvert, ils ne sont jamais appelés, ils ne sont donc pas le problème.

EDIT 2: Après avoir triplé l'état de chaque variable dans les appels de fonction édités, je les ai pratiquement éliminés comme coupables.

Answer 1

Il semble que vous ayez un JTable avec un DoubleRenderer pour l'une de vos colonnes et que les données que vous obtenez contiennent des valeurs non valides pour cette colonne décimale. Probablement quelques caractères alphanumériques au lieu de chiffres seulement.
