[Hibernate-JIRA] Created: (ANN-604) There is no annotation to specify default value for a column

by Nicolae Bucalaete (JIRA)

There is no annotation to specify default value for a column ------------------------------------------------------------ Key: ANN-604 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-604 Project: Hibernate Annotations Issue Type: Bug Affects Versions: 3.3.0.ga Reporter: Nicolae Bucalaete Priority: Critical In hibernate annotation you can't specify default value for a column. If you use xml files for mapping then you have this feature. I consider that this is a major problem with annotation. -- 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-3231) org.hibernate.id.enhanced.TableGenerator throws "IllegalArgumentException: alias not found: tbl" under Oracle

by Király Attila (JIRA)

org.hibernate.id.enhanced.TableGenerator throws "IllegalArgumentException: alias not found: tbl" under Oracle ------------------------------------------------------------------------------------------------------------- Key: HHH-3231 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3231 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.2.6 Environment: Hibernate 3.2.6GA, Oracle 10g Reporter: Király Attila Attachments: hibernate_etg_ora.zip org.hibernate.id.enhanced.TableGenerator always throws the following exception if I want to save a new object to Oracle: java.lang.IllegalArgumentException: alias not found: tbl at org.hibernate.sql.ForUpdateFragment.<init>(ForUpdateFragment.java:36) at org.hibernate.dialect.Dialect.applyLocksToSql(Dialect.java:970) at org.hibernate.id.enhanced.TableGenerator.configure(TableGenerator.java:194) at org.hibernate.id.IdentifierGeneratorFactory.create(IdentifierGeneratorFactory.java:104) I attach an example to this case. The example is loosely based on the tutorial example, that comes with Hibernate. It contains a Person object that is saved to db using the enhanced.TableGenerator as id generator. To keep the zip small only the jars of jdbc driver are included, the jars needed from hibernate distribution are listed in lib/readme.txt. The zip also contains a modified TableGenerator that works with Oracle. This version was made by forum user stomp and more information about it can be read here: http://forum.hibernate.org/viewtopic.php?t=980933 It changes the 194th row of TableGenerator from this.query = dialect.applyLocksToSql( query, lockMap, CollectionHelper.EMPTY_MAP ); to this.query = dialect.applyLocksToSql( query, lockMap, Collections.singletonMap("tbl", new String[] {valueColumnName}) ); -- 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-3771) Best pactice for equals implementation?

by Samppa Saarela (JIRA)

Best pactice for equals implementation? --------------------------------------- Key: HHH-3771 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3771 Project: Hibernate Core Issue Type: New Feature Components: core, documentation Reporter: Samppa Saarela When domain model contains even one lazy reference to an object, default equals fails when it's compared to a) the actual implementation returned by Session.get/load or b) other proxies (at least of different supertype). Overriding equals on a class that uses surrogate id is not that simple. However there is a simple solution to this problem: In domain class, override equals like this: public boolean equals(Object obj) { return this == getImplementation(obj); } public static Object getImplementation(Object obj) { if (obj instanceof HibernateProxy) { return ((HibernateProxy) obj).getHibernateLazyInitializer().getImplementation(); } else { return obj; } } This should result always in comparing object references of actual instances and thus preserve symmetry. It's understandable that you don't wan to publish that kind of getImplementation utility e.g. in Hibernate, but maybe you could support this more directly by implementing Hibernate.equals(Object o1, Object o2) -- 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-2350) 2nd level cache broken for inverse bidirectional one-to-many relation

by Burkhard Graves (JIRA)

2nd level cache broken for inverse bidirectional one-to-many relation --------------------------------------------------------------------- Key: HHH-2350 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2350 Project: Hibernate3 Type: Bug Components: core Versions: 3.2.1 Environment: Database: MySQL, HSQL, ... (seems not to be important) Reporter: Burkhard Graves Attachments: testcase.tgz When using "inverse" one-to-many relations as described in "2.4.6.2.3. Bidirectional association with indexed collections" (http://www.hibernate.org/hib_docs/annotations/reference/en/html/entity.ht...) hibernate is wrong when activating 2nd level cache. See the attached example (unzip in /usr/local/hibernate-annotations-3.2.1.GA, testname=org.hibernate.test.annotations.invonetomany.InverseOneToManyTest).

[Hibernate-JIRA] Created: (HHH-3001) The NoopOptimizer needs to be synchronized

by Maciej Baranowski (JIRA)

The NoopOptimizer needs to be synchronized ------------------------------------------ Key: HHH-3001 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3001 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.2.4.sp1, 3.2.6 Environment: 3.2.6, 3.2.4sp1, Oracle Reporter: Maciej Baranowski When SequenceStyleGenerator is used with Oracle it uses by default NoopOptimizer.

[Hibernate-JIRA] Created: (HHH-3609) Invalid list re-ordering with IndexColumn and OneToMany association

by Martin Kovacik (JIRA)

Invalid list re-ordering with IndexColumn and OneToMany association ------------------------------------------------------------------- Key: HHH-3609 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3609 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.3.1 Environment: Hibernate 3.3.1, Hibernate Tools 3.2.0, H2 database 1.0.69 Reporter: Martin Kovacik I want to map unidirectional OneToMany ordered list using annotations. My mapping is: public class Invoice { // ... @OneToMany(cascade = CascadeType.ALL) @JoinTable( name = "INVOICE_ITEM", joinColumns = {@JoinColumn(name = "invoice_id")}, inverseJoinColumns = {@JoinColumn(name = "item_id")} ) @Cascade(value = org.hibernate.annotations.CascadeType.DELETE_ORPHAN) @IndexColumn(name = "item_order") private List<Item> items = new ArrayList<Item>(); } The mapping of Item is not important here because I just want the association from Invoice to collection of Items to be unidirectional. The problem what hbm2ddl generates: create table INVOICE_ITEM ( invoice_id int8 not null, item_id int8 not null, item_order int4 not null, primary key (invoice_id, item_order), unique (item_id) ); alter table INVOICE_ITEM add constraint FK89837AD3EDA329D foreign key (item_id) references ITEM; alter table INVOICE_ITEM add constraint FK89837AD76A8E2D7 foreign key (invoice_id) references INVOICE; Another problem is how hibernate handles list re-ordering. If I want to change the item order (by manipulating invoice.items list) and then persist the changes hibernate tries to execute following sql: update INVOICE_ITEM set item_id=2 where invoice_id=1 and item_order=0 update INVOICE_ITEM set item_id=1 where invoice_id=1 and item_order=1 However this causes DB to complain about unique item_id constraint (which was generated by hibernate). IMHO hibernate should update just the item_order column. I think that this bug is related to ANN-679 (http://opensource.atlassian.com/projects/hibernate/browse/ANN-679). -- 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-2269) Many-to-one cascade fails with TransientObjectException if the inverse collection is marked CascadeType.DELETE_ORPHAN

by Edward Costello (JIRA)

Many-to-one cascade fails with TransientObjectException if the inverse collection is marked CascadeType.DELETE_ORPHAN --------------------------------------------------------------------------------------------------------------------- Key: HHH-2269 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2269 Project: Hibernate3 Type: Bug Components: core Versions: 3.2.0.cr2, 3.2.1 Environment: Using hibernate annotations. Reporter: Edward Costello Attachments: TestBidirectionalCascade.java When both a many-to-one (child) and it's inverse one-to-many collection (on parent) are cascading. Attempting to save a child directly and cascade the save to the parent throws a TransientObjectException if the parent's collection is mapped CascadeType.DELETE_ORPHAN. For Example, with the classes below: @Entity public class Parent { @OneToMany(mappedBy = "parent") @Cascade(value = {CascadeType.ALL, CascadeType.DELETE_ORPHAN}) Set<DeleteOrphanChild> deleteOrphanChildren; } @Entity public class DeleteOrphanChild { @ManyToOne @Cascade(value = CascadeType.ALL) Parent parent; } Calling session.save() with an instance of the parent will cascade the save to the child as expected. However, calling save on an instance of the child will throw the TransientObjectException below while attempting to cascade the save to the parent. org.hibernate.TransientObjectException: cascade.test.TestBidirectionalCascade$DeleteOrphanChild at org.hibernate.engine.ForeignKeys.getEntityIdentifierIfNotUnsaved(ForeignKeys.java:216) at org.hibernate.collection.AbstractPersistentCollection.getOrphans(AbstractPersistentCollection.java:889) at org.hibernate.collection.PersistentSet.getOrphans(PersistentSet.java:51) at org.hibernate.engine.CollectionEntry.getOrphans(CollectionEntry.java:350) at org.hibernate.engine.Cascade.deleteOrphans(Cascade.java:336) at org.hibernate.engine.Cascade.cascadeCollectionElements(Cascade.java:318) at org.hibernate.engine.Cascade.cascadeCollection(Cascade.java:185) at org.hibernate.engine.Cascade.cascadeAssociation(Cascade.java:160) at org.hibernate.engine.Cascade.cascadeProperty(Cascade.java:108) at org.hibernate.engine.Cascade.cascade(Cascade.java:248) at org.hibernate.event.def.AbstractSaveEventListener.cascadeAfterSave(AbstractSaveEventListener.java:437) at org.hibernate.event.def.AbstractSaveEventListener.performSaveOrReplicate(AbstractSaveEventListener.java:326) at org.hibernate.event.def.AbstractSaveEventListener.performSave(AbstractSaveEventListener.java:180) at org.hibernate.event.def.AbstractSaveEventListener.saveWithGeneratedId(AbstractSaveEventListener.java:108) at org.hibernate.event.def.DefaultSaveOrUpdateEventListener.saveWithGeneratedOrRequestedId(DefaultSaveOrUpdateEventListener.java:186) at org.hibernate.event.def.DefaultSaveOrUpdateEventListener.entityIsTransient(DefaultSaveOrUpdateEventListener.java:175) at org.hibernate.event.def.DefaultSaveOrUpdateEventListener.performSaveOrUpdate(DefaultSaveOrUpdateEventListener.java:98) at org.hibernate.event.def.DefaultSaveOrUpdateEventListener.onSaveOrUpdate(DefaultSaveOrUpdateEventListener.java:70) at org.hibernate.impl.SessionImpl.fireSaveOrUpdate(SessionImpl.java:509) at org.hibernate.impl.SessionImpl.saveOrUpdate(SessionImpl.java:501) at org.hibernate.engine.CascadingAction$1.cascade(CascadingAction.java:134) at org.hibernate.engine.Cascade.cascadeToOne(Cascade.java:213) at org.hibernate.engine.Cascade.cascadeAssociation(Cascade.java:157) at org.hibernate.engine.Cascade.cascadeProperty(Cascade.java:108) at org.hibernate.engine.Cascade.cascade(Cascade.java:248) at org.hibernate.event.def.AbstractSaveEventListener.cascadeBeforeSave(AbstractSaveEventListener.java:412) at org.hibernate.event.def.AbstractSaveEventListener.performSaveOrReplicate(AbstractSaveEventListener.java:261) at org.hibernate.event.def.AbstractSaveEventListener.performSave(AbstractSaveEventListener.java:180) at org.hibernate.event.def.AbstractSaveEventListener.saveWithGeneratedId(AbstractSaveEventListener.java:108) at org.hibernate.event.def.DefaultSaveOrUpdateEventListener.saveWithGeneratedOrRequestedId(DefaultSaveOrUpdateEventListener.java:186) at org.hibernate.event.def.DefaultSaveEventListener.saveWithGeneratedOrRequestedId(DefaultSaveEventListener.java:33) at org.hibernate.event.def.DefaultSaveOrUpdateEventListener.entityIsTransient(DefaultSaveOrUpdateEventListener.java:175) at org.hibernate.event.def.DefaultSaveEventListener.performSaveOrUpdate(DefaultSaveEventListener.java:27) at org.hibernate.event.def.DefaultSaveOrUpdateEventListener.onSaveOrUpdate(DefaultSaveOrUpdateEventListener.java:70) at org.hibernate.impl.SessionImpl.fireSave(SessionImpl.java:537) at org.hibernate.impl.SessionImpl.save(SessionImpl.java:525) at org.hibernate.impl.SessionImpl.save(SessionImpl.java:521) If the DELETE_ORPHAN cascade is removed the save works fine. The attached test case runs against an in memory HSQLDB database. It contains 4 tests, the second test (testSaveChildDeleteOrphan) fails showing the above exception. The other three pass showing that cascading from the parent works and that cascading in both directions remove if the DELETE_ORPHAN cascade is removed. We've only tested this with annotations, we haven't tried to reproduce it using hibernate mapping files. -- 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
