[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: (HBX-1092) hbm2doc with graphing fails on MacOSX

by Avram Cherry (JIRA)

hbm2doc with graphing fails on MacOSX ------------------------------------- Key: HBX-1092 URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-1092 Project: Hibernate Tools Issue Type: Bug Components: hbm2doc Affects Versions: 3.2.0.GA, 3.2.2 Reporter: Avram Cherry In the method org.hibernate.tool.hbm2x.DocExporter.dotToFile, the portions of the command passed to Runtime.exec() are being passed to an escape(String) method that optionally adds quotes to the executable file path and the path to the input file, but only if the OS is not linux. MacOSX is not linux, but adding quotes causes exec() to fail. The solution is to change the following statement: String exeCmd = escape(dotExeFileName) + " -T" + getFormatForFile(outFileName) + " " + escape(dotFileName) + " -o " + escape(outFileName); to: String[] exeCmd = new String[] {dotExeFileName, " -T", getFormatForFile(outFileName), dotFileName, " -o ", outFileName}; If you pass the command and arguments as separate strings within an array to Runtime.exec() you do not need to quote filenames, regardless of platform. A (potentially very harmful) workaround is to pass -Dos.name=Linux to the VM. Please note that I've checked both the 3.2 branch and trunk and both contain the same problem. -- 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-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

[Hibernate-JIRA] Created: (HHH-3527) Null Version Comparator for versioned class due to reuse of Second Level CacheDataDescriptionImpl

by Paul FitzPatrick (JIRA)

Null Version Comparator for versioned class due to reuse of Second Level CacheDataDescriptionImpl ------------------------------------------------------------------------------------------------- Key: HHH-3527 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3527 Project: Hibernate Core Issue Type: Bug Components: caching (L2) Affects Versions: 3.3.1 Environment: 3.3.1 GA, Postgres 8.3.3, EH Cache Reporter: Paul FitzPatrick Priority: Minor When the SessionFactoryImpl constructor builds the EntityPersister for classes, it consults a cache of entityAccessStrategies for all the known second level cache regions. If only some of the classes in that region have version tags, then it is possible the cached EntityRegionAccessStrategy will be created without a Version Comparator. Subsequent calls to load an object using a Criteria query failed with a NullPointerException (stack trace below). The line being executed is "return version!=null && comparator.compare(version, newVersion) < 0;" and in this case "version" is an Integer object and comparator is null. Not sure the appropriate solution. It would seem from an examination of the code that if the EntityRegionAccessStrategy is to be shared, then all classes in the second level cache region _must_ either all have a "version" column or all have no "version" column. Further, it seems implied that if they use a "version" column, then they must all use the exact same data type. If this is the case, then a better error check on the configuration data may be in order.
