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.
Thanks for this great component !

[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.

javax.persistence.criteria.Expression.as() is broken
----------------------------------------------------
Key: HHH-5755
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5755
Project: Hibernate Core
Issue Type: Bug
Components: entity-manager
Affects Versions: 3.6.0
Reporter: Artem Troitskiy
Priority: Minor
When I try to execute criteria query containing typecast to {{String}}
{noformat}
CriteriaQuery<Product> criteria = builder.createQuery( Product.class );
Root<Product> from = criteria.from( Product.class );
criteria.where(builder.like(from.get("partNumber").as(String.class), "1%"));
List<Product> result = em.createQuery( criteria ).getResultList();
{noformat}
I get the following exception
{quote}
org.hibernate.hql.ast.QuerySyntaxException: expecting CLOSE, found '(' near line 1, column 132 [select generatedAlias0 from org.hibernate.ejb.metamodel.Product as generatedAlias0 where cast(generatedAlias0.partNumber as varchar(255)) like :param0]
{quote}
As you can see, SQL type is used in HQL {{cast}} clause. It's caused by {{CriteriaQueryCompiler.RenderingContext.getCastType()}} that erroneously return SQL typename instead of Hibernate typename.

Hello,
I have found something that is a bit strange. 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.
I have checked the forums and found similar problems, maybe they can help more then my post:

I'm getting a
java.lang.IllegalArgumentException: Cannot create TypedQuery for query with more than one return
with a query that returns a View object.
AbstractEntityManager:279, detects as many returns type as there is parameters in the View object, instead of one single result type, the View Object itself.
QueryString example that fails with public <T> TypedQuery<T> createQuery(String jpaqlString, Class<T> resultClass):
"select new WorkContractDto(wc.workContractStartDate, wc.workContractEndDate, wc.workContractEmployeeLastName, wc.workContractSendingStatus) from WorkContract wc where wc.workContractEmployeeLastName = ?1"
