by RAMESH BABU NL (JIRA)

Infinite loop occurs while doing findById on a Parent domain Object having OneToMany relationship with child domain with composite primary key ---------------------------------------------------------------------------------------------------------------------------------------------- Key: ANN-846 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-846 Project: Hibernate Annotations Issue Type: Improvement Affects Versions: 3.4.0.GA Environment: Hibernate Annotations 3.4.0.GA, HSqlDB and Oracle Reporter: RAMESH BABU NL Attachments: Organization.java, OrganizationApplications.java, OrganizationApplicationsPK.java We are using Hibernate annotations version 3.4.0.G.A We are establishing a OneToMany relationship using the annotation @OnetoMany for a Parent and Child domain objects where the child domain has a composite primary key. We have two domain objects Organization [Parent] OrganizationApplications [Child] We want to have a OnetoMany relationship between Organization and OrganizationApplications. As shown below OrganizationApplications contains a composite primary key, of two columns(Organization Id, ApplicationId[foreignkey from other table called APPLICATIONS]) Organizations.java ------------------- @OneToMany(targetEntity=gov.osc.enrollment.backend.domain.OrganizationApplications.class, cascade=CascadeType.ALL, fetch = FetchType.EAGER, mappedBy="id.organization") private Set<OrganizationApplications> organizationApps = new HashSet<OrganizationApplications>(); OrganizationApplications.java --------------------------------------------------------------------- public class OrganizationApplications extends EnvelopeInfo implements Serializable { private static final long serialVersionUID = 1L; @EmbeddedId private OrganizationApplicationsPK id; public OrganizationApplicationsPK getId() { return id; } public void setId(OrganizationApplicationsPK id) { this.id = id; } OrganizationApplicationsPK.java --------------------------------------------------------------------- @Embeddable public class OrganizationApplicationsPK implements Serializable { private static final Long serialVersionUID = 1L; public OrganizationApplicationsPK() { super(); } @ManyToOne @JoinColumn(name="APPLICATION_ID",nullable=false) private Applications application; @ManyToOne(targetEntity=gov.osc.enrollment.backend.domain.Organization.class, cascade=CascadeType.ALL) @JoinColumn(name="ORGANIZATION_ID", referencedColumnName="ORGANIZATION_ID", nullable=false, insertable=true, updatable=true) private Organization organization; public Applications getApplication() { return application; } public void setApplication(Applications application) { this.application = application; } public Organization getOrganization() { return organization; } public void setOrganization(Organization organization) { this.organization = organization; } @Override public boolean equals(Object o) { if (o == this) { return true; } if ( ! (o instanceof OrganizationApplicationsPK)) { return false; } OrganizationApplicationsPK other = (OrganizationApplicationsPK) o; return (this.getOrganization().getId() == other.getOrganization().getId()) && (this.getApplication().getId() == other.getApplication().getId()); } @Override public int hashCode() { final int prime = 31; int hash = 17; hash = hash * prime + ((int) (this.getOrganization().getId() ^ (this.getOrganization().getId() >>> 32))); hash = hash * prime + ((int) (this.getApplication().getId() ^ (this.getApplication().getId() >>> 32))); return hash; } } Please see the attached java files for complete code and also the exception stack trace. Questions: 1. When we do a findById query on Organization table the system goes into infinite loop and never gets out . How ever we are able to insert a record in Organization and its child OrganizationApplications. 2. In the Organization.java domain, if you notice we are using mappedby="id.organization". Is this a valid mapping ? If not why does this parameter work for insert and not for a entityManager.findById, doing so leads to infinite loop. -- 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-3884) NPE with mutable Natuarl Id's

by Michael Kopp (JIRA)

NPE with mutable Natuarl Id's ----------------------------- Key: HHH-3884 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3884 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.2.2 Reporter: Michael Kopp When saving an entity with a mutable natural id hibernate throws the following NPE. java.lang.NullPointerException at org.hibernate.engine.StatefulPersistenceContext.getNaturalIdSnapshot(StatefulPersistenceContext.java:267) at org.hibernate.event.def.DefaultFlushEntityEventListener.checkNaturalId(DefaultFlushEntityEventListener.java:78) at org.hibernate.event.def.DefaultFlushEntityEventListener.getValues(DefaultFlushEntityEventListener.java:162) at org.hibernate.event.def.DefaultFlushEntityEventListener.onFlushEntity(DefaultFlushEntityEventListener.java:113) at org.hibernate.event.def.AbstractFlushingEventListener.flushEntities(AbstractFlushingEventListener.java:196) at org.hibernate.event.def.AbstractFlushingEventListener.flushEverythingToExecutions(AbstractFlushingEventListener.java:76) at org.hibernate.event.def.DefaultFlushEventListener.onFlush(DefaultFlushEventListener.java:26) at org.hibernate.impl.SessionImpl.flush(SessionImpl.java:1000) I checked the code and found the reason: - getNaturalIdSnapshot calls getDatabaseSnapshot and checks the result for NO_ROW but not for null - getDatabaseSnapshot will never return NO_ROW but null if nothing was found hence getNaturalIdSnapshot will produce a NPE if the entity is not in the database already. the fix is simple: change: Object[] entitySnapshot = getDatabaseSnapshot( id, persister ); if ( entitySnapshot == NO_ROW ) { return null; } to Object[] entitySnapshot = getDatabaseSnapshot( id, persister ); if ( entitySnapshot == null ) { return null; } This is still there in trunk as well! -- 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-3256) OptimizerFactory$PooledOptimizer.generate doesn't set keep the in-memory hi_value in sync with the db next_val (after a JBoss restart)

by Tom Muldoon (JIRA)

OptimizerFactory$PooledOptimizer.generate doesn't set keep the in-memory hi_value in sync with the db next_val (after a JBoss restart) -------------------------------------------------------------------------------------------------------------------------------------- Key: HHH-3256 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3256 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.2.6 Environment: Hibernate 3.2.6, MySQL 5 Reporter: Tom Muldoon After a JBoss restart, the in-memory hiValue is -1. As such, the callback.getNextValue( ) method is invoked twice. With an increment size of 50 and a current database next_val of 10000, the PooledOptimizer.generate method returns a value of 10000 (as expected) and sets the in memory hiValue to 10050 (also as expected), however, it sets the db next_val to 10100. Shouldn't the db next_val be kept in sync with the in-memory hiValue (i.e. 10050)? -- 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-4065) Incorrect SQL is used for HQL if the number of values for a filter collection parameter is changed

by Nicklas Nordborg (JIRA)

Incorrect SQL is used for HQL if the number of values for a filter collection parameter is changed -------------------------------------------------------------------------------------------------- Key: HHH-4065 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4065 Project: Hibernate Core Issue Type: Bug Components: query-hql Affects Versions: 3.3.2 Environment: Hibernate 3.3.2 Reporter: Nicklas Nordborg Attachments: trace.txt I think that maybe the fix for HHH-530 has introduced a problem with filters that has a collection-type parameter. If the number of parameters in that collection changes during the lifetime of a SessionFactory the SQL that is used becomes incorrect and either has too many or too few parameter placeholders (eg. '?') in the SQL. There was no problem in Hibernate 3.3.1. A typical error message is: java.sql.SQLException: Parameter index out of bounds. 2 is not between valid values of 1 and 1 Below is some pseudo-code that shows what happens when the number of values in a collection is increased from 1 to 2. The 'memberOf' is a simple filter on the `id` column: `id` IN (:items) String hql = "select n from NewsData n"; List idList = new ArrayList(); idList.add(1); Session s = .... // create new session s.enableFilter("memberOf").setParameterList("items", idList); s.createQuery(hql).list(); // SQL: select .... `News` newsdata0_ where newsdata0_.`id` IN (?) s.close(); idList.add(2); s = ... // create new session s.enableFilter("memberOf").setParameterList("items", idList); s.createQuery(hql).list(); // <--- error here with 3.3.2 but works with 3.3.1 // SQL (3.3.2): select .... `News` newsdata0_ where newsdata0_.`id` IN (?) // SQL (3.3.1): select .... `News` newsdata0_ where newsdata0_.`id` IN (?, ?) I am attaching a file with TRACE-level output from both Hibernate 3.3.2 and 3.3.1. The relevant difference seems to be that in Hibernate 3.3.2 the query plan is cached with: [SQL_TOKEN] SqlFragment: 'newsdata0_.`id` IN (?)' but in Hibernate 3.3.1 with: [SQL_TOKEN] SqlFragment: 'newsdata0_.`id` IN (:memberOf.items)' -- 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-3107) Error with sql generated for set of subclass A in a peer subclass B.

by Austin Mayberry (JIRA)

Error with sql generated for set of subclass A in a peer subclass B. -------------------------------------------------------------------- Key: HHH-3107 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3107 Project: Hibernate3 Issue Type: Bug Affects Versions: 3.2.6 Reporter: Austin Mayberry A mapping such as the following contrived examples does not yield the expected results and causes and error: <class name="com.foo.Foo1" table="FOO1"> <id name="id" type="java.lang.Integer" column="ID" > <generator class="sequence" > <param name="sequence">ID_SEQ</param> </generator> </id> <discriminator column="FOO_TYPE_ID" type="java.lang.Integer"/> <subclass name="com.foo.Foo2" discriminator-value="0"> <join table="FOO2"> <key column="ID"/> <property name="label" type="java.lang.String" column="LABEL" not-null="true" length="255" /> </join> <subclass name="com.foo.BarOne" discriminator-value="1"> <set name="barTwos" inverse="true" > <key> <column name="PARENT_ID" /> </key> <one-to-many class="com.foo.BarTwo" /> </set> </subclass> <subclass name="com.foo.BarTwo" discriminator-value="2"> <join table="BAR"> <key column="ID"/> <many-to-one name="parent" class="com.foo.BarOne" not-null="true" column="PARENT_ID" /> </join> </subclass> </subclass> </class> The sql created to populate the set "bartwos" looks like this looks like: select bartwos0_.PARENT_ID as PA3_1_, bartwos0_.ID as ID1_1_, bartwos0_.ID as ID1_52_0_, bartwos0_.FOO_TYPE_ID as FO2_52_0_, bartwos0_1_.LABEL as LABEL76_0_, bartwos0_2_.PARENT_ID as PA2_87_0_ from FOO1 bartwos0_, FOO2 bartwos0_1_, BAR2 bartwos0_2_ where bartwos0_.ID=bartwos0_1_.ID and bartwos0_.ID=bartwos0_2_.ID and bartwos0_.PARENT_ID=? And yields the following error message: java.sql.SQLException: ORA-00904: "BARTWOS0_"."PARENT_ID: invalid identifier The basic problem is that it should be looking for the property PARENT_ID on BAR2, but it is looking for it on FOO1. -- 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
