[Hibernate-JIRA] Created: (HHH-5024) MetadataContext#registerAttribute does not recognize inherited fields

by Adrian Hummel (JIRA)

MetadataContext#registerAttribute does not recognize inherited fields --------------------------------------------------------------------- Key: HHH-5024 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5024 Project: Hibernate Core Issue Type: Bug Components: entity-manager, metamodel Affects Versions: 3.5.0-CR-2 Environment: Hibernate 3.5.0-CR-2, JPA Modelgen 1.0.0-CR-1 Reporter: Adrian Hummel Priority: Critical Attachments: bugreport.zip The embeddable class {{CustomerId}} (see attached ZIP) inherits from the base class {{AbstractIdentity}} (annotated with {{@MappedSuperclass}}). The metamodel classes for these two classes are correctly generated: {code:title=AbstractIdentity_.java|borderStyle=solid} import javax.persistence.metamodel.SingularAttribute; import javax.persistence.metamodel.StaticMetamodel; @StaticMetamodel(AbstractIdentity.class) public abstract class AbstractIdentity_ { public static volatile SingularAttribute<AbstractIdentity, String> id; } {code} and {code:title=CustomerId_.java|borderStyle=solid} import javax.persistence.metamodel.StaticMetamodel; @StaticMetamodel(CustomerId.class) public abstract class CustomerId_ extends AbstractIdentity_ { } {code} When building the entity manager factory, {{MetadataContext#registerAttribute}} (line 378) tries to resolve the field {{CustomerId_.id}} using {{Class#getDeclaredField}}. This results in a {{NoSuchFieldException}} because the field is declared in the super class {{AbstractIdentity_}}. Proposed solution: Since all field declarations in the metamodel are public, the {{Class#getField}} method should be used instead. -- 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-2879) consolidate approach for id and natural-id loading

by Steve Ebersole (JIRA)

consolidate approach for id and natural-id loading -------------------------------------------------- Key: HHH-2879 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2879 Project: Hibernate3 Issue Type: Improvement Reporter: Steve Ebersole Assignee: Steve Ebersole Currently, natural-id "loading' is only available through some incomplete criteria query hackery. Would like to expose a proper API for performing natural-id loading. In addition, would like this to be consolidated with the effort to cleanup the Session API and so have a unified way to load entities: Session.getLoader( MyEntity.class ).get( id ) Session.getNaturalIdLoader( MyEntity.class ).get( naturalId ) *DISCLAIMER : do not like the term 'loader' here because of ambiguity* -- 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-3853) one-to-one mapping doesn support Primary Key Association

by Amar Singh (JIRA)

one-to-one mapping doesn support Primary Key Association -------------------------------------------------------- Key: HHH-3853 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3853 Project: Hibernate Core Issue Type: Bug Components: envers Environment: Hibernate - core 3.4.0-SNAPSHOT, Hibernate - envers (trunk build from today) Reporter: Amar Singh Attachments: one-to-one-pk.zip one-to-one mapping with primary key association doesn't seem to be working. Eg. Code: <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping package="org.hibernate.envers.test.integration.onetoone.bidirectional" default-lazy="false"> <class name="BidirectionalRefIngPK" table="BIDIRECTIONAL_REFERENCING_ENTITY"> <id name="id" type="long" column="BIDIRECTIONAL_REFERENCING_ID" > <generator class="foreign"> <param name="property">reference</param> </generator> </id> <property name="data"/> <property column="BIDIRECTIONAL_REFERENCING_ID" generated="never" insert="false" lazy="false" name="id" type="long" update="false"/> <one-to-one name="reference" cascade="save-update" class="BidirectionalRefEdPK" constrained="true" /> </class> <class name="BidirectionalRefEdPK" table="BIDIRECTIONAL_REFERENCED_ENTITY"> <id name="longId" type="long" column="BIDIRECTIONAL_REFERENCED_ID"> <generator class="native"/> </id> <property name="data"/> <one-to-one name="referencing" cascade="all" class="BidirectionalRefIngPK" /> </class> </hibernate-mapping> When we try to load a BidirectionalRefIngPK, the underlying query invokes RelatedAuditExpression and since its not a foreign-key based one-to-one association the loading fails in method addToQuery of RelatedAuditExpression at line 52 (relatedEntity==null) with the following exception: Code: "This criterion can only be used on a property that is a relation to another property." TO REPRODUCE ~~~~~~~~~~~~~ Please find a zip file attached which has four files: - BidirectionalPrimaryAssociation.java (actual testng test case) - BidirectionalRefEdPK.java (Entity 1) - BidirectionalRefIngPK.java (Entity 2) - mappings.hbm.xml Please put the three java files in its package (org.hibernate.envers.test.integration.onetoone.bidirectional) and the mapping file in src/test/resources. Now when you run envers tests you should see the failure.

[Hibernate-JIRA] Created: (HHH-3414) fetch profiles

by Steve Ebersole (JIRA)

fetch profiles -------------- Key: HHH-3414 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3414 Project: Hibernate3 Issue Type: New Feature Components: core, metamodel Reporter: Steve Ebersole Assignee: Steve Ebersole Fix For: 3.4 The concept of fetch profiles as we are discussing here is basically to allow users to dynamically affect the mapped fetching strategy for associations at runtime. Consider the following example: <class name="Person"> ... <set name="addresses" lazy="true" fetch="subselect" ...> ... </set> </class> <class name="Address"> ... </class> This follows the normal recommendation to map associations as lazy and use a dynamic fetching strategy (ala HQL/Criteria) to modify this lazy behavior at runtime. The fetaure discussed here would allow the same behavior for loading as well: <hibernate-mapping> <fetch-profile name="person-details"> <fetch path="Person.addresses" style="join"/> </fetch-profile> </hibernate-mapping> Or: <hibernate-mapping> <class name="Person"> ... <fetch-profile name="person-details"> <fetch path="addresses" style="join"/> </fetch-profile> <set name="addresses" lazy="true" fetch="subselect" ...> ... </set> </class> </hibernate-mapping> Now, doing: session.enableFetchProfile( "person-details" ).get( Person.class, 1 )... will load Person#1 as well as their addresses in a single joined query. -- 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

It's caused by {{CriteriaQueryCompiler.RenderingContext.getCastType()}} that erroneously return SQL typename instead of Hibernate typename. -- 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

For @ManyToOne association properties in an @Embeddable class the cascade PERSIST, SAVE-UPDATE option is not working well (not sure for the other cascade types), if the entities associated with ManyToOne are transient. I have created a unit test to check it and I have it attached to this issue. It is a maven2 project, and needs Oracle to run it. If I save the associated entites, then everything works fine, also the data structure is created well.
