Mauvais élément du Datatable retourné pour la suppression
Bonjour,
Je dispose d'une Datatable initialement remplie avec des enregistrements depuis la base de données. Pour chaque ligne il existe une colonne ACTION contenant un seul bouton pour le moment qui sert à la supression.
Dans un premier temps, la suppression d'un élément s'effectue correctement mais après lorsque j'essaie de supprimer un deuxième élément une exception qui s’élève :
Code:
javax.faces.el.EvaluationException: org.hibernate.StaleStateException: Batch update returned unexpected row count from update [0]; actual row count: 0; expected: 1
Et lorsque j'essaie de déboguer la méthode de suppression je trouve que le premier élément supprimé est celui qui s'appelle avec la méthode ce qui déclenche l'exception ci-dessous
