3.2.6 breaks querying by a property of an entity in a collection
----------------------------------------------------------------
Key: HHH-3168
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3168
Project: Hibernate3
Issue Type: Bug
Affects Versions: 3.2.6
Reporter: Michael Newcomb
@NamedQuery(name="q", query="select a from A a where
a.stuff.name=:name")
class A
{
@ManyToMany
@MapKey(name = "name")
@Sort(type = SortType.NATURAL)
SortedMap<String, C> stuff;
}
class B
{
@Basic
String name;
}
class C
extends B
{
}
Please excuse the brevity of the example (code is not on internet accessible machine), but
just dropping in 3.2.6 hibernate3.jar causes an error in DotNode.propertyType is set to
the type of 'name' and fails all the checks in resolve() and calls
checkLhsIsNotCollection() which fails...
When looking at the logs...
3.2.5:
[DotNode] dereferenceCollection(): Created...
[FromReferenceNode] Resolved : a.stuff -> .
[DotNode] getDataType() : name -> ...StringType
[FromReferenceNode] Resolved : a.stuff.name -> xxx.name
[HqlSqlBaseWalker] select : finishing up...
- at this point there is some logs about 'Using FROM fragment' and then it prints
another AST tree with something about querySpaces...
- then it starts to check the next query
3.2.6:
[DotNode] dereferenceCollection(): Created...
[FromReferenceNode] Resolved : a.stuff -> .
[DotNode] getDataType() : name -> ...StringType
- then it starts to check the next query
- it is missing all the extra stuff after the 'getDataType() : name ->
...StringType'

Michael Newcomb commented on HHH-3168:
--------------------------------------
This is not a help question? 3.2.6 breaks the above query...
If the query was incorrect then perhaps a bug report should be filed against < 3.2.6
for allowing the query to work?

Michael Newcomb commented on HHH-3168:
--------------------------------------
Query works in 3.2.6 when explicitly specifying inner join...
"select a from A a inner join a.stuff as s with s.name=:name"
So, unless you are going to update section 14.4 where it says "HQL supports two forms
of association joining: implicit and explicit" and remove all the collection type
supporting code from DotNode.java...
This is a bug...

In 3.2.5, everything works as expected... In 3.2.6, it fails to initialize the entity...
Here is an example that demonstrates this bug:

import java.util.HashSet;
import java.util.List;
import javax.persistence.Id;
import javax.persistence.OneToMany;
import javax.persistence.Entity;
import javax.persistence.NamedQueries;
import javax.persistence.NamedQuery;
import javax.persistence.Query;
@Entity
@NamedQueries(value = {
@NamedQuery(
name = "Cat.by.kitten.name",
query = "select c from Cat c inner join c.kittens as kitten with
kitten.name=:name"),
@NamedQuery(
name = "Cat.by.kitten.name2",
query = "select c from Cat c where c.kittens.name=:name")
}
)
public class Cat
{
@Id
protected String name;
@OneToMany
protected Set<Cat> kittens = new HashSet<Cat>();
public Cat(String name)
{
this.name = name;
}
public Set<Cat> getKittens()
{
return kittens;
}
public static void main(String... args)
{
EntityManager entityManager;
entityManager.getTransaction().begin();
Cat mom = new Cat("mom1");
Cat kitten1 = new Cat("mom1.kitten1");
Cat kitten2 = new Cat("mom1.kitten2");
entityManager.persist(mom);
entityManager.persist(kitten1);
entityManager.persist(kitten2);
mom.getKittens().add(kitten1);
mom.getKittens().add(kitten2);
mom = new Cat("mom2");
kitten1 = new Cat("mom2.kitten1");
kitten2 = new Cat("mom2.kitten2");
entityManager.persist(mom);
entityManager.persist(kitten1);
entityManager.persist(kitten2);
mom.getKittens().add(kitten1);
mom.getKittens().add(kitten2);
entityManager.getTransaction().commit();
Query query = entityManager.createNamedQuery("Cat.by.kitten.name");
query.setParameter("name", "mom1.kitten1");
for (Cat cat : (List<Cat>) query.getResultList())
{
System.out.println(cat.name);
}
query = entityManager.createNamedQuery("Cat.by.kitten.name2");
query.setParameter("name", "mom1.kitten1");
for (Cat cat : (List<Cat>) query.getResultList())
