[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: (ANN-843) Version increment not triggered on @OneToOne property modification having inverse owner

by Guenther Demetz (JIRA)

Version increment not triggered on @OneToOne property modification having inverse owner --------------------------------------------------------------------------------------- Key: ANN-843 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-843 Project: Hibernate Annotations Issue Type: Bug Affects Versions: 3.4.0.GA Environment: Hibernate 3.3.1.GA , Microsoft SQL Server Reporter: Guenther Demetz Priority: Minor Attachments: Testcase.jar In the revised "Java Persistence with Hibernate" book by Christian Bauer and Gavin King on page 464 there's written following about versioning: "If you use Hibernate as JPA provider ... every value-typed property modification .. triggers a version increment." Now I saw that Version increment indeed is not triggered on @OneToOne properties having an inverse owner (= mappedBy setted). This allows several concurrent transactions to set the association from same object towards different targets without having a OptimistickLockException at commit. This violates the ToOne policy! (Hibernate detects the inconsistency later when loading the property from database: org.hibernate.HibernateException: More than one row with the given identifier was found) Please see attached junit-testcase for reproducing the problem. regards Guenther Demetz -- 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-3872) Criteria on alias causes partial collection materialization

by Adrian Moos (JIRA)

Criteria on alias causes partial collection materialization ----------------------------------------------------------- Key: HHH-3872 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3872 Project: Hibernate Core Issue Type: Bug Components: query-criteria Affects Versions: 3.3.0.CR1 Reporter: Adrian Moos I have a parent entity with a one-to-many assocation to a child entity: <hibernate-mapping package="ch.bedag.a11.ccinfo.business.entity" default-lazy="false"> <class name="Parent" table="PARENT"> <id name="id" type="long" column="ID" unsaved-value="null"> <generator class="sequence"> <param name="sequence">SEQ_T_PARENT</param> </generator> </id> <set name="children" cascade="all-delete-orphan" inverse="true"> <key column="PARENT_ID" foreign-key="CHILD_FK1"/> <one-to-many class="Child"/> </set> </class> <class name="Child" <id name="id" type="long" column="ID" unsaved-value="null"> <generator class="sequence"> <param name="sequence">SEQ_T_CHILD</param> </generator> </id> <property name="businessKey" column="BUSINESSKEY" not-null="true"/> </class> </hibernate-mapping> I then do: Criteria parentCriteria = aSession.createCriteria(Parent.class); parentCriteria.createAlias("children", "c", CriteriaSpecification.LEFT_JOIN); parentCriteria.setResultTransformer(CriteriaSpecification.DISTINCT_ROOT_ENTITY); parentCriteria.add(Restrictions.eq("c.businessKey", 123456789)); List parents = parentCriteria.list(); Expected behaviour: Since each parent in parents is a materialized entity, I'd expect its children set to contain all its children. Observed behaviour: It contains only children with matching business key. Is my expectation correct? -- 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: (HHH-3608) DB sequence numbers are not unique when using the pooled SequenceStyleGenerator in multiple JVMs with the same DB

by Matthias Gommeringer (JIRA)

DB sequence numbers are not unique when using the pooled SequenceStyleGenerator in multiple JVMs with the same DB ----------------------------------------------------------------------------------------------------------------- Key: HHH-3608 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3608 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.3.1, 3.3.0.SP1, 3.3.0.GA, 3.2.6 Environment: Hibernate 3.2.6, Oracle (any version) Reporter: Matthias Gommeringer Priority: Blocker Attachments: PooledOptimizerTest.java We have several Application Servers (=JVMs) running each of them using Hibernate-Objects with the SequenceStyleGenerator+pooled configured. In unpredictable time intervals it happens that hibernate assigns the same ID to two completely different objects which results in a UniqueConstraintViolation exception from the database. Here an example with a description where hibernate fails: DB-Sequence setup: start=0 increment=2 PooledOptimizer.generate() with 2 threads (first assignment of hiValue/value): JVM-1 JVM-2 value=0=callback.nextval value=2=callback.nextval hiValue=4=callback.nextval hiValue=6=callback.nextval The problem's cause is in the PooledOptimizer.generate: when it initializes the value+hiValue for the first time it invokes callback.nextValue() twice which may provide values that do not belong to each other. The reason is that between the assignment of "value" and "hiValue" another JVM can retrieve a DB sequence value from the callback which leads to an inconsistent "value" and "hiValue" relation (see example above). A fix that works for multiple JVMs would be to invoke the "callback.getNextValue()" maximum once per "optimizer.generate()" call: public synchronized Serializable generate(AccessCallback callback) { if ( hiValue < 0 ) { value = callback.getNextValue(); hiValue = value + incrementSize; } else if ( value >= hiValue ) { value = callback.getNextValue(); hiValue = value + incrementSize; } return make(value++); } I attached a testcase that prooves the described problem (you can see that the IDs "2" and "3" are assigned two times). I would be very thankful if this problem could be fixed very soon since it is a showstopper which occurs very unpredictably. -- 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-3551) Boolean substitution in informix

by Rouvignac (JIRA)

Boolean substitution in informix -------------------------------- Key: HHH-3551 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3551 Project: Hibernate Core Issue Type: Bug Components: query-sql Affects Versions: 3.3.1 Environment: Hibernate 3.2 Informix 9.40 Reporter: Rouvignac HQL Query : select order from Order order where order.printed = ? Parameter : true, false, Boolean.TRUE or Boolean.FALSE When the request is executed we get the following error : SQLSTATE: IX000 SQL CODE: -674 674: Routine (equal) can not be resolved. If as parameter we use "t" ot "f" everything works fine but it will not work with other DB. As a workaround we can use : property name="hibernate.query.substitutions">true t, false f</property> I investigated in Dialects : Dialect.java public String toBooleanValueString(boolean bool) { return bool ? "1" : "0"; } PostgreSQLDialect.java public String toBooleanValueString(boolean bool) { return bool ? "true" : "false"; } InformixDialect.java uses Dialect.java toBooleanValueString method. In my mind toBooleanValueString should be added to InformixDialect.java as follow : public String toBooleanValueString(boolean bool) { return bool ? "t" : "f"; } -- 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-4511) Problems with polymorphic queries with SINGLE_TABLE inheritance strategy

by Karoly Gacsal (JIRA)

Problems with polymorphic queries with SINGLE_TABLE inheritance strategy ------------------------------------------------------------------------ Key: HHH-4511 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4511 Project: Hibernate Core Issue Type: Bug Components: envers Affects Versions: 3.5.0.Beta-1 Environment: envers 1.2.1 Hibernate 3.3.2 Reporter: Karoly Gacsal Attachments: ChildAuditing.java Inheritance strategy is SINGLE_TABLE (discriminator). When I query for ParentType I do not get ChildType instances in the result, but ParentType instances. I checked the problem against envers 1.2.1/Hibernate 3.3.2 and against Hibernate 3.5.0.Beta-1 too. The testcase "\src\test\java\org\hibernate\envers\test\integration\inheritance\single\ChildAuditing.java" passes, but when I change the two sides of the equals method in testPolymorphicQuery()'s second assert the testcase fails, because the expected result is a ChildEntity, but in the result we get an instance of ParentEntity. Attached you can find the testcases changed by me. -- 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
