hibernate - No se pudo inicializar la colección de forma pausada, no se cerró ninguna sesión o sesión(a pesar de que se buscó con entusiasmo)

jpa-2.0

Question

De acuerdo, obtengo la excepción anterior en una aplicación en la que estoy trabajando. Estoy usando JPA e hibernate. Aquí está la stacktrace:

WARNING: #{commissionController.saveCommission}: javax.persistence.PersistenceException: org.hibernate.LazyInitializationException: failed to lazily initialize a collection, no session or session was closed

Al depurar, noté que parece provenir de una parte del código en la entidad Formulario:

@PostLoad
public void removeHiddenFields() {
if(fields.isEmpty()) {
return;//don''t do anything if there are no fields
}
for(int i = 0; i < fields.size(); i++) {
if(fields.get(i).isHidden()) {
fields.remove(fields.get(i));
}
}
}

La parte "fields.isEmpty ()" arroja la excepción hacia arriba.

Según lo que he leído, se supone que esto se puede corregir configurando una colección para que se pueda obtener con entusiasmo. Supongo que el problema es la colección de campos. Pero ...

@JoinColumn(name = "FORM")
@OneToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER)
private List<Field> fields = new ArrayList<Field>();

Ya está buscando ansiosamente. Tuve que hacer eso para resolver otro problema encontrado anteriormente en el desarrollo.

¿Cual podría ser el problema?

Adicional:

Las entidades del formulario se cargan como tales:

Hay una clase que maneja las consultas de la base de datos para la entidad Form. Hay dos métodos para obtenerlos de la base de datos (dependiendo del tipo de formulario).

public List<Form> getAllActiveForms() {
TypedQuery<Form> query = this.getEntityManager().createNamedQuery(
"getAllActiveForms", Form.class);
return query.getResultList();
}
public List<Form> getAllInactiveForms() {
TypedQuery<Form> query = this.getEntityManager().createNamedQuery(
"getAllInactiveForms", Form.class);
return query.getResultList();
}

Las consultas nombradas se definen como tales en la entidad Formulario:

@NamedQueries({
@NamedQuery(name = "getAllActiveForms", query = "SELECT f FROM Form f WHERE f.isEnabled=true"),
@NamedQuery(name = "getAllInactiveForms", query = "SELECT f FROM Form f WHERE f.isEnabled=false") })

El "currentForm" que se utiliza en la función se selecciona de una de esas listas.

También noté en este momento que otra función en la aplicación que simplemente actualiza un Formulario ahora arroja el mismo tipo de excepción. Esta vez proviene de la función merge ():

@Transactional
public Form updateAndReturn() {
getInstance().setTimestamp(System.currentTimeMillis());
Form f = getEntityManager().merge(getInstance());
getEntityManager().flush();
return f;
}

Answer 1

Esto fue causado por un error en Hibernate. Lo encontré aquí: http://issues.jboss.org/browse/JBAS-5474

Funciona desde la versión 4.1.8 ( https://hibernate.onjira.com/browse/HHH-6043 )

El problema es con @PostLoad, que aparentemente no hace las cosas en el orden correcto.
