[Hibernate-JIRA] Created: (ANN-814) OneToOne Unidirectional Support

by Rachit (JIRA)

OneToOne Unidirectional Support ------------------------------- Key: ANN-814 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-814 Project: Hibernate Annotations Issue Type: Bug Affects Versions: 3.4.0.GA Environment: Oracle 10g, Java 1.5 Reporter: Rachit Priority: Blocker I tried hard for unidirectional OneToOne mapping as below: @Entity @Table(name = "PARTY") public class Party{ private Person person; private String key; @OneToOne(fetch = FetchType.EAGER, cascade = CascadeType.ALL,) @PrimaryKeyJoinColumn(name = "PARTY_ID", referencedColumnName = "PERSON_PARTY_ID") public Person getPerson() { return person; } public void setPerson(Person person) { this.person = person; } @Id @GeneratedValue(generator = "system-uuid") @GenericGenerator(name = "system-uuid", strategy = "uuid") @Column(name = "PARTY_ID", nullable = false) public String getKey() { return key; } private void setKey(String key) { this.key = key; } } and it is one-to-one mapped to Person as: @Entity(name = "Person") @Table(name = "PERSON") public class Person { private String key; @Id @Column(name = "PERSON_PARTY_ID") public String getKey() { return key; } public void setKey(String key) { this.key = key; } } Now in Person, I deliberately dont have sysUUID as generated as then it generates a unique value for person and the association gets lost. With this mapping hibernate throws the following exception : Caused by: org.hibernate.id.IdentifierGenerationException: ids for this class must be manually assigned before calling save(): Person. I read and saw constrained="true" being used in mapping files, which I couldnt use as there is no attribute like it in OneToOne annotation.

[Hibernate-JIRA] Created: (EJB-385) JPA method of merge failed to insert deleted records from database

by Hari (JIRA)

JPA method of merge failed to insert deleted records from database ------------------------------------------------------------------- Key: EJB-385 URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-385 Project: Hibernate Entity Manager Issue Type: Improvement Components: EntityManager Affects Versions: 3.2.0.ga Environment: 3.2.6.ga, Weblogic,JPA, Windows Reporter: Hari The following is my requirement. Suppose i have a record in database with id say, 12. i have retrieved this using a JPQL query and convert it into a transfer object ,done some processing and going to remerge this after converting it to a new entity but the id set in the new entity is same as old one ie 12. Now just before calling entityManger.merge i have deleted the record with id 12 from database. The issue is the merge opeartion is not inserting the record in database at all. But if the id set in the entity is one which is never occured in the database,the merge operation will insert the record with the id set from teh application. Is there any work around/fix for this issue.

[Hibernate-JIRA] Created: (HHH-4066) JPA compatibility problem

by Albert Kurucz (JIRA)

JPA compatibility problem ------------------------- Key: HHH-4066 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4066 Project: Hibernate Core Issue Type: Bug Affects Versions: 3.3.2 Environment: Hibernate Core 3.3.2, problem is independent from database type (actually appeared with Derby 10.4.2) Reporter: Albert Kurucz POJO Entity with 100% JPA annotations, as long as the Class did not implement the Map interface everything worked fine (save to and load from database). After the Class implemented the Map interface, during object persistence, 'get' was called with '$type$' parameter, and 'get' responded with IllegalArgumentException (in accordance to its design). Workaround implemented: get now responds to this call by returning getClass().getName() BUT Hibernate should not need this workaround if it is 100% JPA compliant. On the above example the Map interface of the Entity Class had no connection with persisted variables, only transients. In the JPA spec there is no restriction what I know of, which would disallow the implementation of Map by an Entity Class. In the JPA spec there is no requirement what I know of, which would require and Entity Class which implement the Map interface to implement the Map interface in any special way (like 'get' responding to '$type$'). Correct me if I am wrong. -- 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-3223) PersistentMap.remove() incorrect on uninitialized, non-extra-lazy map

by Michael Newcomb (JIRA)

PersistentMap.remove() incorrect on uninitialized, non-extra-lazy map --------------------------------------------------------------------- Key: HHH-3223 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3223 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.3.0.CR1 Reporter: Michael Newcomb Please have a look at PersistentMap.remove() and compare it to PersistentMap.put(). The put() was fixed HHH-2476 and the same fix needs to be applied to remove(). Please refer to HHH-2584 for the patch: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2584 Copied from HHH-2584: Essentially, an uninitialized PersistentMap loses the first remove() into it if defined as non-extra-lazy. The underlying cause is the code in PersistentMap#remove() which attempts to readElementByIndex(). In the case of non-extra-lazy, readElementByIndex() returns the UNKNOWN marker object which is supposed to be used to signal that the delegate map is now initialized and to remove the element directly from the map. Long story short, PersistentMap#remove() does not properly check the return value from readElementByIndex() and react accordingly. WORKAROUND: Have a copy of PersistentMap.java in your source tree with the patch applied...

[Hibernate-JIRA] Created: (EJB-364) Composite PK and @GeneratedValue

by Radosław Smogura (JIRA)

Composite PK and @GeneratedValue -------------------------------- Key: EJB-364 URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-364 Project: Hibernate Entity Manager Issue Type: Bug Affects Versions: 3.3.2.GA Environment: Hibernate 3.2.6 Glassfish PostgreSQL Reporter: Radosław Smogura Priority: Critical [code] For class like this @Entity @IdClass(FooId.class) /* Seq / Table generator */ public class Foo { int id1; int id2; @Id public getId1() { return id1; } public setId1(....); @Id @GeneratedValue(strategy=AUTO/IDENTITY/SEQUENCE/TABLE) public int getId2() { return id2; } public void setId2(.....); } [/code] Id1 is set manully, but id2 is unchanged i this situation hibernate doesn't generates PK and tries to insert NULL causing error. Specification requires assigning of generated value with @Id properties. Part 2.4.1 defines two types of PKs simple and composite and part 9.1.9 says about PKs in generally. (SEQ or IDENTITY is specification depended, but PostgreSQL support it and Hibernate should support it too). -- 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-3028) Memory consumption when query cache is enabled

by Markus Heiden (JIRA)

Memory consumption when query cache is enabled ---------------------------------------------- Key: HHH-3028 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3028 Project: Hibernate3 Issue Type: Bug Components: caching (L2), core Affects Versions: 3.2.5 Environment: Hibernate 3.2.5, Oracle 9i Reporter: Markus Heiden As discussed in the hibernate-dev mailing list from 9.11.2007 to 12.11.2007 this bug describes a memory consumption issue which is located in ActionQueue/EntityAction. Some snippets from ActionQueue: private ArrayList executions; public void execute(Executable executable) { final boolean lockQueryCache = session.getFactory().getSettings().isQueryCacheEnabled(); if ( executable.hasAfterTransactionCompletion() || lockQueryCache ) { executions.add( executable ); } ... } This code leads to a kind of memory leak, because if the "executable" is added to "executions", the related entity which is referenced from the "executable" is prevented from being garbage collected until the transaction ends. So if one needs to insert large amounts of transient objects in one transaction, there is no chance to get rid of the inserted objects by flushing and evicting them, if e.g. the query cache is enabled. One solution to this problem might be to rework the above "if" condition to only add objects to "executions" if this is really needed. The problem is to determine when it is really needed. Some snippets from EntityAction (which implements Executable): private final Object instance; public final Serializable getId() { if ( id instanceof DelayedPostInsertIdentifier ) { return session.getPersistenceContext().getEntry( instance ).getId(); } return id; } public final Object getInstance() { return instance; } Another solution might be to set the reference to the related entity (field "instance" in EntityAction) to null after flushing. This does not prevent "executions" from being filled, but the related entities might be garbage collected and so the memory consumption is acceptable. The problem is that subclasses of EntityAction use the "instance" field for post transaction work. The are currently two workarounds to this problems: 1) To always disable the query cache 2) To use shorter transactions Workaround 1 is not really acceptable, because it prohibits the use of a very useful feature. Workaround 2 is sometimes acceptable but not wanted in most cases, because it breaks transactional safety. -- 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
