[Hibernate-JIRA] Created: (HHH-3123) NullPointerException on invalid HQL query with an extra brace

by Geoffrey De Smet (JIRA)

NullPointerException on invalid HQL query with an extra brace ------------------------------------------------------------- Key: HHH-3123 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3123 Project: Hibernate3 Issue Type: Bug Components: query-hql Affects Versions: 3.2.5 Reporter: Geoffrey De Smet Priority: Trivial This query: "select p from IndividueleRekeningKasPO p left join fetch p.irTotalen inner join fetch p.toegangIndividueleRekeningKas tirkas where tirkas.authorityRef in (:authorityref)) and p.soort = :soort and p.id > 0" gives a NPE. The strange thing is that this query executes: "select p from IndividueleRekeningKasPO p left join fetch p.irTotalen inner join fetch p.toegangIndividueleRekeningKas tirkas where tirkas.authorityRef in (:authorityref)) and p.id > 0" both are invalid, because there is a closing brace to much in "(:authorityref))". -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira

[Hibernate-JIRA] Created: (HHH-3230) getEntityName() throws org.hibernate.TransientObjectException: proxy was not associated with the session

by Howard M. Lewis Ship (JIRA)

getEntityName() throws org.hibernate.TransientObjectException: proxy was not associated with the session -------------------------------------------------------------------------------------------------------- Key: HHH-3230 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3230 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.2.2 Environment: Mac OS X, JDK 1.5 Reporter: Howard M. Lewis Ship I'm retrieving an entity that contains a OneToMany relationship. The master entity is retrieved, within a transaction, via Session.get(Class,Serializable). @Entity public class MapUnitSurvey extends ActiveDO { @ManyToOne(fetch = FetchType.LAZY) private VegetationType vegetationType; } @Entity public class VegetationType extends AbstractEnum { } ActiveDO and AbstractEnum are abstract base classes with @MappedSuperclass. I retrieve the vegationType: VegetationType type = survey.getVegetationType(); Then I need the type's entity name String entityName = session.getEntityName(type); This fails with the TransientObjectException. Inspecting with the debugger, I see that type is a CGLIB-enhanced proxy, and that there's a fully initialized bean in the target field of the proxy. I'll attach a screenshot of some debugging data. In summary; the entity was retrieved via a lazy fetch, appears the be correct, seems to be in the session and yet the exception occurs. I've tried to resolve this by re-fetching the object from the session, and a few other tries, with no luck. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira

[Hibernate-JIRA] Created: (HHH-3332) Hibernate duplicate then child entity's on merge

by Rodrigo de Assumpção (JIRA)

Hibernate duplicate then child entity's on merge ------------------------------------------------ Key: HHH-3332 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3332 Project: Hibernate3 Issue Type: Bug Affects Versions: 3.2.6 Environment: JDK 1.6 Oracle 9i Hibernate 3.2.6 Hibernate Annotations 3.3.1 Hibernate EntityManager 3.3.2 Standalone Running Reporter: Rodrigo de Assumpção Priority: Critical The method merge from EntityManager causes a duplication of child entity's. class Father: @OneToMany(mappedBy = "father", cascade={CascadeType.ALL}, fetch=FetchType.LAZY) private List<Child> childList; class Child: @ManyToOne @JoinColumn(name = "ID_FATHER") private Father father; class BugTest EntityManagerFactory emf = Persistence.createEntityManagerFactory("JpaTestHB"); EntityManager em = emf.createEntityManager(); Father f = (Father) em.createQuery("SELECT f FROM Father f WHERE f.id = 1").getSingleResult(); Child c = new Child(); c.setFather(f); f.getChildList().add(c); em.getTransaction().begin(); em.merge(f); em.getTransaction().commit(); The execution of BugTest Class causes tow insert's on table "child". If you change the fetch mode to EAGER (into Father class) the problem not occurs. I make the same test with Toplink, and it make a unique insert, normal. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira

[Hibernate-JIRA] Created: (ANN-747) @CollectionOfElements does not cascade on delete

by Nicole Rauch (JIRA)

@CollectionOfElements does not cascade on delete ------------------------------------------------ Key: ANN-747 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-747 Project: Hibernate Annotations Issue Type: Bug Affects Versions: 3.3.1.GA Environment: Hibernate 3.2.6 GA Database: H2 1.0.72 Reporter: Nicole Rauch Consider the following constellation: @Embeddable public class Foo { // ... } @Entity public class Bar { @CollectionOfElements private Set<Foo> myFoos; // ... } When I persist a Bar object that contains some Foos, and when I later decide to delete the Bar object, I get a foreign key constraint violation error message because the Foo objects, which contain a reference to the Bar object that owns them, are not deleted automatically. I would expect the default behaviour to be "on delete cascade" because the Foo objects are embeddables, thus they cannot exist on their own without the Bar object that owns them. But there is no way to tell Hibernate to cascade: - the @OnDelete annotation is only allowed for OneToMany relations - the @Cascade annotation is being ignored - there is no "cascade" property for the CollectionOfElements So my question is: Why does the cascading not occur automatically, and how do I tell Hibernate to cascade anyways? Thanks a lot in advance, Nicole -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira

[Hibernate-JIRA] Created: (HHH-3273) One-to-Many relationship not working with custom Loader

by Darren Hicks (JIRA)

One-to-Many relationship not working with custom Loader -------------------------------------------------------- Key: HHH-3273 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3273 Project: Hibernate3 Issue Type: Bug Affects Versions: 3.2.6, 3.2.5, 3.2.4, 3.2.3, 3.2.2, 3.2.1 Environment: hibernate-3.2.6.jar Reporter: Darren Hicks Within the context of a One-to-Many relationship, NamedQueryCollectionInitializer .initialize() never actually populates the PersistantBag on the parent after it calls query.setCollectionKey( key ).setFlushMode( FlushMode.MANUAL ).list() to retrieve the children. This is documented in the forums here: http://forums.hibernate.org/viewtopic.php?t=986428 Additionally, the poster has a fix posted which may solve the problem, or at least lay out the groundwork for a solution. Here is the proposed implementation of NamedQueryCollectionInitializer.initialize(): public void initialize(Serializable key, SessionImplementor session) throws HibernateException { if (log.isDebugEnabled()) { log.debug("initializing collection: " + persister.getRole() + " using named query: " + queryName); } // TODO: is there a more elegant way than downcasting? AbstractQueryImpl query = (AbstractQueryImpl) session .getNamedSQLQuery(queryName); if (query.getNamedParameters().length > 0) { query.setParameter(query.getNamedParameters()[0], key, persister .getKeyType()); } else { query.setParameter(0, key, persister.getKeyType()); } List list = query.setCollectionKey(key).setFlushMode(FlushMode.MANUAL) .list(); // Uh, how 'bout we save the collection for later retrieval? CollectionKey collectionKey = new CollectionKey(persister, key, session .getEntityMode()); for (Object object : session.getPersistenceContext() .getCollectionsByKey().keySet()) { if (collectionKey.equals(object)) { PersistentCollection persistentCollection = session .getPersistenceContext().getCollection(collectionKey); Serializable[] serializables = new Serializable[list.size()]; for (int i = 0; i < list.size(); i++) { serializables[i] = persister.getElementType().disassemble( list.get(i), session, persistentCollection.getOwner()); } persistentCollection.initializeFromCache(persister, serializables, persistentCollection.getOwner()); persistentCollection.setSnapshot(key, persistentCollection .getRole(), serializables); persistentCollection.afterInitialize(); session.getPersistenceContext().getCollectionEntry( persistentCollection).postInitialize( persistentCollection); } } } -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira

[Hibernate-JIRA] Created: (EJB-328) Missing flush before lock() when LockModeType is AUTO

by Per Olesen (JIRA)

Missing flush before lock() when LockModeType is AUTO ----------------------------------------------------- Key: EJB-328 URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-328 Project: Hibernate Entity Manager Issue Type: Bug Components: EntityManager Affects Versions: 3.3.1.GA Environment: core: 3.2.5.ga entitymanager: 3.3.1.ga annotations: 3.3.0.ga Reporter: Per Olesen Priority: Minor When I try to WRITE lock() a newly persisted entity using entityManager.lock, I get a StaleObjectStateException, telling me that some other transaction updated or deleted the row. I am doing this in the same transaction (persist and lock). By digging into the code, I see that the exception is thrown inside the SelectLockingStrategy.lock method, around these lines: ResultSet rs = st.executeQuery(); try { if ( !rs.next() ) { if ( factory.getStatistics().isStatisticsEnabled() ) { factory.getStatisticsImplementor() .optimisticFailure( lockable.getEntityName() ); } throw new StaleObjectStateException( lockable.getEntityName(), id ); } } The query executed here is the one which performs the select on id with FOR UPDATE. This select finds nothing, hence the exception. Setting show_sql = true shows me, that no insert is performed. Debugging the flush mode tells me, that it is set to AUTO. Shouldn't AUTO flush mode have the side effect, that a flush is performed before a query? Performing an explicit flush, before the lock, makes everything green :-), so this is my current work-around. Here is the exception (sanitized for company info): org.springframework.orm.jpa.JpaOptimisticLockingFailureException: nested exception is javax.persistence.OptimisticLockException Caused by: javax.persistence.OptimisticLockException at org.hibernate.ejb.AbstractEntityManagerImpl.wrapStaleStateException(AbstractEntityManagerImpl.java:643) at org.hibernate.ejb.AbstractEntityManagerImpl.throwPersistenceException(AbstractEntityManagerImpl.java:600) at org.hibernate.ejb.AbstractEntityManagerImpl.lock(AbstractEntityManagerImpl.java:379) ...

[Hibernate-JIRA] Created: (HHH-3007) Unchanged persistent set gets marked dirty on session.merge()

by Lars Koedderitzsch (JIRA)

Unchanged persistent set gets marked dirty on session.merge() ------------------------------------------------------------- Key: HHH-3007 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3007 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.2.5 Reporter: Lars Koedderitzsch Persistent sets are marked dirty on session.merge() even if there have been no changes to the collection. This is especially painful when the collection is immutable and results in an "changed an immutable collection instance" exception on flush. I tracked the behaviour down a bit and believe the problem to be in CollectionType.replace(). Here the passed in orginal PersistentSet is replaced by a plain HashSet in this line: Object result = target == null || target == original ? instantiateResult( original ) : target; The "result" object (HashSet) is then passed to the CollectionType.replaceElements() method (instead of the original PersistentSet). In CollectionType.replaceElements() the code to clear the dirty state of the collection does not execute anymore, because the passed-in "original" collection is the described HashSet and *not* the original PersistentSet. This way the PersistentSet remains marked dirty. A workaround is to manually clear the dirty state of an immutable collection after merge but before flush. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
