Bug fix related to CriteriaQuery (JPA) when using XML mappings
--------------------------------------------------------------
Key: HHH-6100
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6100
Project: Hibernate Core
Issue Type: Patch
Affects Versions: 3.6.2
Environment: hibernate-(core, entitymanager...)-3.6.2.Final
hibernate-jpa-2.0-api-1.0.0.Final
MySQL 5.1
Spring 3.0.5.RELEASE
Reporter: JOUFFRE Nelly
Priority: Critical
Hi,
I use XML mapping and wanted to implement the following query using CriteriaQuery.
CriteriaBuilder cb = entityManager.getCriteriaBuilder();
CriteriaQuery<MyClass> cq = cb.createQuery(MyClass.class);
Root<MyClass> objRoot = cq.from(MyClass.class);
List<MyClass> results = entityManager.createQuery(cq).getResultList();
(Actually my query is more complex than that but it was the first step.)
The first bug was that query generated the following jpql
select generatedAlias0 from null as generatedAlias0
This was because the org.hibernate.mapping.PersistentClass.jpaEntityName attribute was not set
Once I fixed it if tried to add a WHERE clause which was
cq.where(cb.equal(objRoot.get("embeddablePkId").get("embeddablePkIdAttribute"), "valueToSearch"));
which resulted into a NullPointerException because the org.hibernate.mapping.RootClass.declaredIdentifierProperty attribute was not set for simple and embeddable PK
Theses 2 attributes are well set but only when using annotation mappings because they are set via the AnnotationBinder.
In my case, with XML mapping, it calls the HbmBinder so these attributes are never set.
Here are my bug fixes, hope this help.
Cheers,

[Hibernate-JIRA] Created: (HHH-6204) JoinColumn on non key field fails to populate collection

JoinColumn on non key field fails to populate collection
--------------------------------------------------------
Key: HHH-6204
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6204
Project: Hibernate Core
Issue Type: Bug
Components: core
Affects Versions: 4.0.0.Alpha3, 3.6.4, 4.0.0.Alpha2, 3.6.3, 4.0.0.Alpha1, 3.6.2, 3.6.1, 3.6.0, 3.6.0.CR2, 3.6.0.CR1, 3.6.0.Beta4, 3.6.0.Beta3, 3.6.0.Beta2, 3.6.0.Beta1, 3.3.2
Environment: EAP 5 (hibernate 3.3.2), hibernate 3.6.x, 4.0.x , probably eap4 as well
Reporter: Chris Sams

To duplicate the issue, create three tables in a database with no declared primary or foreign keys. Map entities to two of the tables. One of these entities has a primitive @Id; the other has an @EmbeddedId. Both entities contain an additional field used to join with the third table and populate a collection.
This works with the entity that has a primitive @Id but for the entity with @EmbeddedId, trying to do anything with the collection after calling the getter results in:
javax.ejb.EJBException: org.hibernate.PropertyAccessException: could not get a field value by reflection getter of jboss.example.DoesNotWorkPk.id1
at org.jboss.ejb3.tx.Ejb3TxPolicy.handleExceptionInOurTx(Ejb3TxPolicy.java:77)
....
Caused by: org.hibernate.PropertyAccessException: could not get a field value by reflection getter of jboss.example.DoesNotWorkPk.id1
at org.hibernate.property.DirectPropertyAccessor$DirectGetter.get(DirectPropertyAccessor.java:58)
....
Caused by: java.lang.IllegalArgumentException: Can not set java.lang.String field jboss.example.DoesNotWorkPk.id1 to jboss.example.DoesNotWork
at sun.reflect.UnsafeFieldAccessorImpl.throwSetIllegalArgumentException(UnsafeFieldAccessorImpl.java:146)
I've attached a sample project. The relevant files are Works.java, DoesNotWork.java, and DoesNotWorkPk.java
There's also data.sql along with the java files to populate a mysql db, but I think any DB will do.
