[EJB2.1 Entity] [CMP] Risk to loose modifications

[CMP] Risk to loose modifications

Bonjour,
voila je cree un bean entite avec cmp
le probleme lorsque je veux recuperer une liste et afficher pour chaque champ la valeur d'une propriete ca plante
en fait ca plante seulement sur le get :arf:
et il m'affiche comme erreur :
Code:

1 2 3 4 2004-02-17 13:54:21,531 : JOnASMachineEjbBean.ejbStore : Impossible to store org.objectweb.jorm.api.PExceptionIO: Risk to loose modifications to class [Machine]: problematic SQL query -> {UPDATE MACHINE SET mFamSfam = ?, mDatel = ?, mNbRp = ?, mPas = ?, mPays = ?, mNoCli = ?, mSa = ?, mSens = ?, mNum = ?, mCodl = ?, mTrait = ?, mLibc = ?, mTraduc = ? WHERE mNum = ?} at jorm.rdb.mysql.MachineBinding.write(MachineBinding.java:152) ...
alors que je n'ai pas ecris la requete update et je ne sais pas ou la trouver pour reparer cette erreur
d'avance merci

c sur le getMLibc que ca plante dis moi si tu veux autre chose

je ne vois pas, a priori ca m'a l'air correct.

Quelle est la Primary Key sur Machine (nom de table(s)) ?

la primary key est mNum

ben voila, le truc que je trouve curieux, c'est que dans l'update, il y a un set mNum.

D'une je ne vois pas pourquoi il tenterait un update, de deux, faire un set mNum, c'est etrange.

M'enfin admettons. Je n'ai rien vu sur google, j'essaierais 2 choses:

1) faire tourner la meme chose sur Jboss (mais ca peut prendre du temps)

2) regarde la trace complete pour voir ce qu'il fait entre ton get() et le MachineBinding.write, et tenter d'en deduire une piste...

Voila la trace complete

mais ce n'est pas la meme erreur !!??

Sur ca, y a de l'info, est-ce que ton bean utilise un java.sql.* ?
