Replace recursive validation algorithm with a ConstraintIterator ---------------------------------------------------------------- Key: BVAL-39 URL: http://opensource.atlassian.com/projects/hibernate/browse/BVAL-39 Project: Bean Validation Issue Type: Improvement Components: ri-general Reporter: Hardy Ferentschik Assignee: Hardy Ferentschik Priority: Minor Introduce a ConstraintValidator which given a bean finds all constraints to validate and makes them accessible for validation via an iterator.

[Hibernate-JIRA] Created: (HHH-3214) Update unit tests and config files to use non-depracated Oracle dialects

by Gail Badner (JIRA)

Update unit tests and config files to use non-depracated Oracle dialects ------------------------------------------------------------------------ Key: HHH-3214 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3214 Project: Hibernate3 Issue Type: Bug Affects Versions: 3.2.6 Reporter: Gail Badner Assignee: Gail Badner Fix For: 3.2.x There are still references to OracleDialect and Oracle9Dialect in hibernate.properties and unit tests. These dialects are depracated so references to them in unit tests and config files (e.g, hibernate.properties) should be changed to refer to non-deprecated dialects. -- 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-3528) FETCH JOIN query doesn't work in a StatelessSession

by Oscar Pearce (JIRA)

FETCH JOIN query doesn't work in a StatelessSession --------------------------------------------------- Key: HHH-3528 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3528 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.3.1, 3.2.6 Environment: Hibernate core 3.3.1 and 3.2.6, HSQLDB 1.8.0 and PostgreSQL 8.1 Reporter: Oscar Pearce Attachments: slsession.zip, StatelessSessionImpl.patch A query with an explicit JOIN FETCH, such as the following: from DomainObject obj join fetch obj.a fails when run in a StatelessSession, giving the following exception: org.hibernate.SessionException: proxies cannot be fetched by a stateless session at org.hibernate.impl.StatelessSessionImpl.immediateLoad(StatelessSessionImpl.java:243) at org.hibernate.proxy.AbstractLazyInitializer.initialize(AbstractLazyInitializer.java:95) at org.hibernate.proxy.AbstractLazyInitializer.getImplementation(AbstractLazyInitializer.java:140) at org.hibernate.proxy.pojo.javassist.JavassistLazyInitializer.invoke(JavassistLazyInitializer.java:190) The attached zip file contains a small project (buildable with maven) that demonstrates the problem. Applying the patch to StatelessSessionImpl fixes it. The cause of the problem is with the internalLoad method of StatelessSessionImpl. The method currently first tries to generate a proxy and, only if no proxy is available, then it uses the data that it loaded as part of the query. The patch changes it to use any loaded data from the query in preference to creating a proxy. (I suspect that the check for eager should be omitted, and that an exception should be thrown if getEntity fails and no proxy can be created, but I don't know the code well enough to be sure of that.) -- 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

How is this possible in HQL? I tried to see if there is any such problem submitted already from the forums, but I could not find one. Please let me know the link if this is already discussed. Here is the problem: Table A Table B I want to use Select a.field1, b.field2 from A a left outer join B b on a.field1 = b.field1 Thanks, Ravi -- 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-3522) Null value cannot be cache using hibernate

by Lao Shing Kit (JIRA)

Null value cannot be cache using hibernate -------------------------------------------- Key: HHH-3522 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3522 Project: Hibernate Core Issue Type: Bug Components: caching (L2) Environment: Hibernate 3.3.1, Ehcache 1.5, Java1.5 Reporter: Lao Shing Kit I'm using Hibernate with 2nd level cache using Ehcache. We found that if the result returned using session.get() (searching by primary key) is NULL, the value will not be cached in 1st level and 2nd level cache and SQL will be fired to database. There is no problem if the value retuurned is not null for the same entity. I have debug using the hibernate and ehcache source and I'm sure that the cache is enabled and called properly. Actually the null value is expected to be cached also. I have browser all hibernate and ehcache documentation and forum and no related config is available. So, is it a bug? Thanks all for your help! -- 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-3455) Component polymorphism (<subclass> within <component>)

by Jasper Blues (JIRA)

Component polymorphism (<subclass> within <component>) ------------------------------------------------------ Key: HHH-3455 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3455 Project: Hibernate3 Issue Type: Improvement Components: core Reporter: Jasper Blues The following feature request occurs on the Hibernate forums from time to time - it would be especially useful in mapping complex legacy schemas: <class name="Critter"> <component name="breathingStrategy" class="BreathingStrategy"> <discriminator column="BREATHING_STRATEGY" type="integer" /> <subclass name="Lungs" discriminator-value="0" > <set name="alveoli"> <key column="CRITTER_ID" /> <one-to-many class="Alveolus" /> </set> </subclass> <subclass name="Gills" discriminator-value="1" > <set name="alveoli"> <key column="CRITTER_ID" /> <one-to-many class="Gill" /> </set> </subclass> </component> </class> Will a patch that implements this feature be accepted? What do you think if there was an option to inherit a discriminator from the owning entity? How about some convention over configuration? By default the discriminator from the owning entity is inherited, unless one is supplied at the component level. Would an equivalent annotation mapping be required? -- 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
