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 :
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
