Unable to define/override @Id(s) on a subclass
Bonjour,
Suite à un héritage avec une surclasse et dont les deux sont des entités.
J’obtiens une erreur récurrente.
Unable to define/override @Id(s) on a subclass: model.Runner
J'ai beau appliquer les consignes des exemples, rien à faire.
Pouvez-vous m'aider ?
Merci
