Illegal attempt to associate a collection with two open sessions
Salut,
J ai un petit soucie lorsque j essaye de supprimer un objet dans ma base de donnée.
J'effectue le code suivant depuis mon managed bean :
Code:

public String deleteList() {
ec.log("Begin - deleteList()");
try {
for (int i = 0; i < dataList.size(); i++) {
selectedData = dataList.get(i);
if (selectedData.getIsSelected()) {
languageService.deleteLanguage(selectedData);
this.deleteSelectedFromDataList();
ec.log("deleteList(), selectedData to delete:"
+ selectedData);
}
}
selectedData = null;
ec.log("End - deleteList()");
return GO_LIST;
} catch (RuntimeException ex) {
ec.handleError(ERROR_DELETE, ErrorLevel.WARNING, ex);
UtilGui.setJSFErrorMessage("error_delete_list", ex);
return GO_LIST;
}
} |
et hibernate me throw une exception sur cette ligne :
Code:
1
2
|
languageService.deleteLanguage(selectedData); |
Et dans mon service j ai le code suivant :
Code:
1
2
3
4
5
|
public void deleteLanguage(Language lang) {
// TODO Auto-generated method stub
languageDbDAO.delete(lang.getDbEntity());
} |
et le code de mon DAO :
Code:
1
2
3
4
5
6
7
8
9
10
11
12
|
public void delete(LanguageDb persistentInstance) {
ec.log("deleting LanguageDb instance");
try {
getHibernateTemplate().delete(persistentInstance);
ec.log("delete successful");
} catch (HibernateException he) {
ec.handleError("HibernateException", ErrorLevel.ERROR, he);
} catch (DataAccessException dae) {
ec.handleError("DataAccessException", ErrorLevel.FATAL, dae);
}
} |
Et voici le log :
