Contrainte implicite avec un ValueObject

Bonjour,

je sais que ce post date mais j'ai exactement le même problème.

J'ai une classe IndividualTrainingPlan qui contient des "Trainee". Lorsque je recupere me IndividualTrainingPlan j'ai une erreur :

TypeError: Error #1034: Echec de la contrainte de type*: conversion de Object@23cc1b79 en vo.TraineeVo impossible

Pourtant, lorsque je recupere ma liste de Trainee, les objets sont bien typés en "Trainee"

voici mon code

D'autre part, j'ai l'impression qu'il y a un problème de cache au niveau blazeDs. Lorsque le serveur tomcat blazeds est lancé, je lance mon projet via flex builder puis je recupere par exemple ma liste de trainee. Ensuite, j'ajoute un trainee dans la base de donnée. Je ferme mon application, je la relance depuis flex builder et quand je veux recupérer mes trainee, il me renvoie les anciennes données sans le nouveau trainee..8O
Y a t'il un moyen de spécifier à blazeds qu'il doit refaire la requete et pas utiliser son cache ?

Merci
