I encounter a java.lang.StackOverflowError when using the updated CVS.
I'll try to give some details about the context, but I didn't dig very far
in castor code.
Attached is the mapping file.
The code causing the exception is :
DBVersion lo_version = lo_vue.version;
lo_version.setDate(new Date());
//l'entr�e � modifier
DBEntree lo_entree = null;
DBEntree lo_entreeTemporaire = getEntreeTemporaire();
try {
Database lo_db = jdo.getDatabase();
lo_db.setAutoStore(true);
try {
log.debug("\t<transaction>");
lo_db.begin();
log.debug("\t\t<cr�ation de " + lo_entree + ">");
//inclusion de la cat�gorie dans la transaction
lo_entree = (DBEntree) lo_db.load(DBEntree.class,
lo_vue.idObjetPrincipal);
if (lo_vue.direct) {
//�changer les donn�es entre l'entr�e et la version
String lo_tmp;
lo_tmp = lo_entree.getDescription();
lo_entree.setDescription(lo_version.getDescription());
lo_version.setDescription(lo_tmp);
lo_tmp = lo_entree.getNom();
lo_entree.setNom(lo_version.getNom());
lo_version.setNom(lo_tmp);
//l'URL change tj, nouveau fichier ou nouvelle adresse
//MAIS v�rifier pr�sence fichier avant
lo_tmp = lo_entree.getURL();
lo_entree.setURL(lo_version.getURL());
lo_version.setURL(lo_tmp);
Date lo_date = lo_entree.getDate();
lo_entree.setDate(lo_version.getDate());
lo_version.setDate(lo_date);
lo_version.setRaison(lo_vue.remarque);
lo_entree.addVersion(lo_version);
}
else {
//lo_db.update(lo_entreeTemporaire);
lo_entreeTemporaire =
(DBEntree) lo_db.load(DBEntree.class,
lo_entreeTemporaire.getId());
lo_entreeTemporaire.addVersion(lo_version);
}
//inclusion de l'utilisateur (load car risque de conflit si
update)
Integer lo_idUtilisateur = lo_vue.utilisateur.getId();
lo_version.setUtilisateur(
(DBUtilisateur) lo_db.load(DBUtilisateur.class,
lo_idUtilisateur));
//enfin on rend persistente la nouvelle version
lo_db.create(lo_version);
log.debug("\t</transaction>");
lo_db.commit();
log.debug("</connexion>");
lo_db.close();
}
catch (PersistenceException e) {
log.error("Impossible de sauver la donn�e : " + e);
throw new DatabaseException("Impossible de sauver la donn�e");
}
finally {
//rien � mettre (g�r� par castor)
}
}
catch (PersistenceException e) {
log.error("Impossible d'ouvrir la connexion : " + e);
throw new DatabaseException("Impossible d'ouvrir la connexion");
};
(hope you won't blame me to much for writing such code - DBVersion is a new
object not persistent before the transaction).
The exception occurs when calling lo_db.create(lo_version) on Castor's code
:
public int getPriority() {
if ( _priority == -1 ) {
int maxPrior = 0;
for ( int i = 0; i < _fhs.length; i++ ) {
if ( _fhs[i].isPersistanceCapable() && _fhs[i].isStored()
&&
_fhs[i].getFieldClassMolder().isKeyGeneratorUsed() ) {
maxPrior = Math.max( maxPrior,
_fhs[i].getFieldClassMolder().getPriority()+1 );
}
/* should an "if case" for add _ids[i].isForeginKey() in the
future */
}
_priority = maxPrior;
}
return _priority;
}
"_fhs[i].getFieldClassMolder().getPriority()" keeps returning the same
"ClassMolder fr.improve.bdi.mapping.jdo.DBCat" object resutling in an infini
te loop.
Hope there are enough clues to help you fix the problem. Otherwise I can
send you my code and database creation script.
