Hi,
I get an Error form code the following line of code
Quote:
Iterator i = HibernateUtil.getCurrentSession().createQuery("from svs where leistung_id = " + curLeistung.getId() + " order by datum desc").list().iterator();
Why and who can i fix it?
First I post the stack trace and then the involved classes:

This is the Controller Class throwing the error in method getLeistungSelectionList

Set <Leistung> leistungList = this.organisation.getLeistungSet();
Iterator iterator = leistungList.iterator();

while (iterator.hasNext()){

Iterator i = HibernateUtil.getCurrentSession().createQuery("from svs where leistung_id = " + curLeistung.getId() + " order by datum desc").list
