[Hibernate-JIRA] Created: (ANN-756) @Column annotation ignored when placed on entity's @Id property

by sagi mann (JIRA)

@Column annotation ignored when placed on entity's @Id property --------------------------------------------------------------- Key: ANN-756 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-756 Project: Hibernate Annotations Issue Type: Bug Affects Versions: 3.3.1.GA Environment: hib core 3.2.6, my sql 5 Reporter: sagi mann Hibernate docs specify that when using a compound key class, a Hibernate optional feature is to place @Column annotations within the key class. The observed behavior is that Hibernate ignores @Column if placed ANYWHERE ELSE, for example, on the entity's ID properties. In other words, the standard JPA way of annotating ID fields is not working under Hibernate, and the "optional" feature is mandatory. Example how to reproduce (see comments inside the code regarding the inconsistency above). Accessors were omitted for clarity: // the identity class @Entity public class SecurityIdentity implements Serializable { public SecurityIdentity() {} @Id @Column(name="IDENTITY_ID") @GeneratedValue public Long getId() ... @Column(name="IDENTITY_NAME") public String getName() ... @Override public boolean equals(Object o) ... @Override public int hashCode() ... } // the domain class @Entity public class SecurityDomain implements Serializable { public SecurityDomain() {} @Id @Column(name="DOMAIN_ID") @GeneratedValue public Long getId() ... @Column(name="DOMAIN_NAME") public String getName() ... @Override public boolean equals(Object o) ... @Override public int hashCode() ... } // the domain-identity mapping class @Entity @IdClass(pu1.DomainIdentityPK.class) public class DomainIdentity implements Serializable { public DomainIdentity() {} @Id public Long getDomainId() ... @Id public String getUserAlias() ... @ManyToOne @JoinColumn(name="IDENTITY_ID") public SecurityIdentity getSecurityIdentity() ... @ManyToOne @JoinColumn(name="DOMAIN_ID", insertable=false, updatable=false) public SecurityDomain getSecurityDomain() { return securityDomain; } public void setSecurityDomain(SecurityDomain securityDomain) { this.securityDomain = securityDomain; this.domainId = (securityDomain != null ? securityDomain.getId() : null); } private SecurityDomain securityDomain; } // the map key class public class DomainIdentityPK implements Serializable { public DomainIdentityPK() { } /********* @Column inconsistency - cannot be placed inside the entity - only inside the PK class *******/ @Column(name="DOMAIN_ID") public Long getDomainId() ...

[Hibernate-JIRA] Created: (HHH-2608) allow delete-orphan cascade style in one-to-one mapping

by Joe Kelly (JIRA)

allow delete-orphan cascade style in one-to-one mapping ------------------------------------------------------- Key: HHH-2608 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2608 Project: Hibernate3 Issue Type: New Feature Components: core Affects Versions: 3.2.4 Environment: 3.2.4, DB2 v8 Reporter: Joe Kelly Please allow the cascade-style "delete-orphan" for one-to-one relationships. When I try to use that cascade style, I get the exception "org.hibernate.MappingException: single-valued associations do not support orphan delete". I realize that the reference manual says "Note that single valued associations (many-to-one and one-to-one associations) do not support orphan delete." But why? I can think of many cases where you WOULD want parent-child semantics in a one-to-one relationship. For example, I have encountered some legacy databases where an entity has all of its fields stored in one table EXCEPT for an optional large field (e.g. a blob field) that is stored in another table, presumably for some performance or storage optimization reason. In this case the two tables are joined with a one-to-one relationship, using a shared primary key. Here are some hypothetical tables, classes and mappings that illustrate this example: company ( company_id (PK) name ) company_extra ( company_extra_id (PK), (FK referencing company.company_id) some_extra_info ) class Company { int companyId; String name; CompanyExtra companyExtra; } class CompanyExtra { int companyExtraId; String someExtraInfo; Company company; } <class name="Company" table="company"> <id name="companyId" column="company_id"> <generator class="sequence"> <param name="sequence">COMPANY_SEQ</param> </generator> </id> <property name="name" column="name" /> <one-to-one name="companyExtra" class="CompanyExtra" cascade="all, delete-orphan" /> </class> <class name="CompanyExtra" table="company_extra"> <id name="companyExtraId" column="company_extra_id" unsaved-value="null"> <generator class="foreign"> <param name="property">company</param> </generator> </id> <property name="someExtraInfo" column="some_extra_info" /> <one-to-one name="company" class="Company" constrained="true" /> </class> For the purposes of this example, CompanyExtra is a child of Company and belongs to one and only one instance of Company. It cannot be shared between Company instances and it cannot be an orphan (i.e. it cannot exist without a parent Company). Also, CompanyExtra is optional so you can have a Company without any associated CompanyExtra during Company's lifecycle. To me, it seems natural and logical that if you set Company.companyExtra to null, and save Company, Hibernate should automatically delete the associated record in the company_extra table if the delete-orphan cascade style is configured (which, of course, it not currently allowed). This is what I want to do when editing an existing Company instance: aCompany = session.load(...); aCompany.setCompanyExtra(null); aCompany.setName("some new name"); session.save(aCompany); // automatically deletes company_extra record For now, I think the workaround is to explicitly delete the CompanyExtra instance in Java code but that just doesn't seem natural to me and it isn't transparent. I do NOT want to do this: aCompany = session.load(...); companyExtra = aCompany.getCompanyExtra(); // ***extra, unnatural method call aCompany.setCompanyExtra(null); aCompany.setName("some new name"); session.save(aCompany); session.delete(companyExtra); // ***another extra, unnatural method call -- 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-573) Many-to-many with Attributes (Attribute-class with two @ManyToOne mappings as @Id) not possible

by Christian Köberl (JIRA)

Many-to-many with Attributes (Attribute-class with two @ManyToOne mappings as @Id) not possible ----------------------------------------------------------------------------------------------- Key: ANN-573 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-573 Project: Hibernate Annotations Type: Bug Components: binder Versions: 3.2.1 Environment: Hibernate+Annotations 3.2.1-ga, HSQLDB 1.8.0.7 Reporter: Christian Köberl Attachments: manytomanybug.zip Im trying to map the following relation: Order 1-n OrderLine m-1 Product where the OrderLine contains an amount of the ordered product. The problem seems to be multiple @Id in combination with @ManyToOne: @Entity @Table(name = "order_line") // @IdClass(OrderLinePK.class) public class OrderLine implements Serializable { @Id @ManyToOne(targetEntity = Order.class) @JoinColumn(name = "order_id", nullable = false) private Order order; @Id @ManyToOne(targetEntity = Product.class) @JoinColumn(name = "product_id", nullable = false) ... } Hibernate maps the OrderLine class in the following way: DEBUG SchemaUpdate:149 - create table order_line (product varbinary(255) not null, order varbinary(255) not null, amount integer, primary key (order)) (maybe this relates to http://opensource.atlassian.com/projects/hibernate/browse/ANN-435) When I add an IdClass to the OrderLine, I get the following exception: Initial SessionFactory creation failed.org.hibernate.AnnotationException: mappedBy reference an unknown target entity property: model.OrderLine.order in model.Order.lineItems The example is attached as a runnable Maven2-Project, just run mvn test. The test dao.OrderDaoAnnotationTest fails. In the project I also tried to map the same classes with hbm-Files and this works (dao.OrderDaoHbmTest). -- 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-4744) Incorrect audit entity for TABLE_PER_CLASS with abstract classes (results in query error)

by Volker Schmidt (JIRA)

Incorrect audit entity for TABLE_PER_CLASS with abstract classes (results in query error) ----------------------------------------------------------------------------------------- Key: HHH-4744 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4744 Project: Hibernate Core Issue Type: Bug Components: envers Affects Versions: 3.5.0-Beta-2, 3.2.0.ga Reporter: Volker Schmidt Attachments: envers-1.2.2.ga-hibernate-3.3.patch, trunk.patch The configuration code of Envers does not check the abstract flag of a PersistentClass. Thus the created audit entity is not declared as being abstract. Abstract entities do not have concrete tables. Without declaring the audit entity of a super class as being abstract, queries include a table (that does not exist) for the abstract super class. I have added a patch for the trunk and for Envers 1.2.2. -- 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
