[Hibernate-JIRA] Created: (HHH-3724) Bug in determining the getter method for property

Bug in determining the getter method for property
--------------------------------------------------
Key: HHH-3724
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3724
Project: Hibernate Core
Issue Type: Bug
Components: core
Affects Versions: 3.3.1
Environment: hibernate-core-3.3.1.GA.jar, Oracle Express Edition 10g
Reporter: Senthil
Priority: Minor
I have an entity class with a property "String nextOnError" mapping to the database column "varchar nextOnError". I have a getter method "String getNextOnError()" defined in the class. But I also have another method "boolean isNextOnError()" for my other processing in the application. I was expecting hibernate would pick the getter method "String getNextOnError()" as the getter method but it is not. It is always picking the "boolean isNextOnError()" and resulting in "Class cast exception: java.lang.Boolean" during insertion. This is because, for each property, in the class "org.hibernate.property.BasicPropertyAccessor", the method "getterMethod(Class theClass, String propertyName)" is looping through all the getter methods with no arguments. The loop breaks when it finds any method starts with either "isNextOnError()" or "getNextOnError()". Unfortunately, in my case, it always ends up with "boolean isNextOnError()". I think the correct way is to check all the methods for starting with get... and if nothing is found, then start looking for method starting with 'is...' .
Thanks.

Attachments: orderby_bug.zip
I have a OneToMany Relationship between ??ClientEntity?? and ??ChildEntity??. Both inherit from ??SuperEntity??.
{code:title=SuperEntity.java|borderStyle=solid}
@Entity
@Inheritance(strategy = InheritanceType.JOINED)
public class SuperEntity
{
@Id
protected int id;
protected int position = 0;
{code}
Here is the Relationship-Definition of ClientEntity
{code:title=ClientEntity.java|borderStyle=solid}
public class ClientEntity
extends SuperEntity
{
public ClientEntity(int id)
{
this.id = id;
}
@OneToMany(fetch = FetchType.EAGER)
@JoinColumn(name = "parent_id")
@OrderBy("position")
List<ChildEntity> childs = new ArrayList<ChildEntity>();
{code}
The ??position??-Attribute (as well as the column) is located in the ??SuperEntity?? (Parent of ChildEntity), and should be used to order the entries of the list.
{code:title=OrderByWithInheritanceTEst.java|borderStyle=solid}
ClientEntity find = entityManager.find(ClientEntity.class, 1);
{code}
If I load the Entity with the find-Method or a NamedQuery the Exception beneath occurs:
Hibernate fills in the tablename of the SuperEntity after the alias of the tablename of the ChildEntity and in front of the columnname.
Hibernate indicates the wrong mapping at startup time of the SessionFactory. It prints out the following log:
{code}
orderByFragment(order-by)
> sortSpecification({sort specification})
> sortKeySpecification(sort key)
> sortKey($PlaceHolder$.SuperEntity.position)
{code}
*$PlaceHolder$.SuperEntity.position*
The SQL-Output of Hibernate-Log (see the last part of the statement) shows that the wrong pattern above is used to address the position-column.
{code}
Hibernate: select cliententi0_.id as id0_1_, cliententi0_1_.position as position0_1_, childs1_.parent_id as parent2_0_3_, childs1_.id as id3_, childs1_.id as id0_0_, childs1_1_.position as position0_0_ from ClientEntity cliententi0_ inner join SuperEntity cliententi0_1_ on cliententi0_.id=cliententi0_1_.id left outer join ChildEntity childs1_ on cliententi0_.id=childs1_.parent_id left outer join SuperEntity childs1_1_ on childs1_.id=childs1_1_.id where cliententi0_.id=? order by childs1_.SuperEntity.position asc
{code}
*childs1_.SuperEntity.position asc*
Beside the Wrong *SuperEntity*-Part the ??PlaceHolder?? has been replaced by the alias of the ChildEntity -table, whereas the alias of the SuperEntity-table would be the correct replacement.

[Hibernate-JIRA] Created: (HHH-3500) Hibernate fails to resolve the correct orderby column in SQL when using inheritance hierarchy
by Joonas Koivunen (JIRA)
Hibernate fails to resolve the correct orderby column in SQL when using inheritance hierarchy
---------------------------------------------------------------------------------------------
Key: HHH-3500
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3500
Project: Hibernate Core
Issue Type: Bug
Affects Versions: 3.3.0.GA
Environment: Derby 10.4.2.0 (http://db.apache.org)
Reporter: Joonas Koivunen
I have an inheritance hierarchy:
@Entity("abstractBaseClass")
AbstractBaseClass
- ConcreteClass1
- ConcreteClass2
- ConcreteClass3
AbstractBaseClass has:
- @Id long id;
- String name;
@Entity("concreteClass1") ConcreteClass1 has a @OneToMany(mappedBy="concreteClass1") List<ConcreteClass2>
@Entity("concreteClass2") ConcreteClass2 has a @OneToMany(mappedBy="concreteClass2") List<ConcreteClass3> and a reference to @ManyToOne ConcreteClass1.
@Entity("concreteClass3") ConcreteClass3 has a reference to @ManyToOne ConcreteClass2.
After adding a @OrderBy("name") annotation to the getter "List<ConcreteClass3> ConcreteClass2.getConcreteClass3s()" and afterwards accessing the association through an ConcreteClass2 instance I get:
SELECT
cc3_concrete.cc2_id,
cc3_concrete.id,
cc3_base.name,
cc3_concrete.cc2_id AS cc2_id_2
FROM
cc3 cc3_concrete
INNER JOIN
abstractBaseClass cc3_base ON cc3_concrete.id = cc3_base.id
WHERE
cc3_concrete.cc2_id = ?
ORDER BY
abstractBaseClass.name asc
(I edited hibernate's naming of entities in SQL to be a bit more clearer).
Ordering by "abstractBaseClass.name" causes the problem here; it's obvious that it should had been "cc3_base.name" but for some reason hib just uses the entityname.column_name in the SQL.
Another strange thing is that the foreign key column "cc2_id" is being included twice in the results? It is included in the select wheter or not @OrderBy exists.
Inheritance strategy used is javax.persistence.InheritanceType.JOINED.

@OrderBy don't quote identifiers
--------------------------------
Key: ANN-807
URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-807
Project: Hibernate Annotations
Issue Type: Bug
Affects Versions: 3.4.0.GA
Environment: Hibernate 3.3.1.GA, MS SQL Server 2000
Reporter: StarBreeze
@OrderBy annotation ignoring quote identifiers.
Test case.
1. Mapping class:
import java.io.Serializable;
import java.util.List;
import javax.persistence.*;
@Entity
@Table(name = "Category")
public class Category implements Serializable {
private static final long serialVersionUID = 1L;
private Integer id;
private String name;
private Integer order;
private Category parent;
private List<Category> children;
@Id
@Column(name = "CategoryId")
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
@Column(name = "Name")
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
@Column(name = "`Order`")
public Integer getOrder() {
return order;
}
public void setOrder(Integer order) {
this.order = order;
}
@ManyToOne()
@JoinColumn(name = "ParentCategoryId")
public Category getParent() {
return parent;
}
public void setParent(Category parent) {
this.parent = parent;
}
@OneToMany(cascade = CascadeType.ALL, mappedBy = "parent", fetch = FetchType.EAGER)
@OrderBy("order")
public List<Category> getChildren() {
return children;
}
public void setChildren(List<Category> children) {
this.children = children;
}
}
2. Fetch code:
Criteria criteria = getSession().createCriteria(Category.class);
criteria.add(Restrictions.eq("name", "Indexes"));
Category category = (Category) criteria.uniqueResult();
Hibernate generates correct select part with wrong "order by":
select this_.CategoryId as CategoryId1_1_, this_.Name as Name1_1_, this_.[Order] as Order3_1_1_, this_.ParentCategoryId as ParentCa4_1_1_, children2_.ParentCategoryId as ParentCa4_3_, children2_.CategoryId as CategoryId3_, children2_.CategoryId as CategoryId1_0_, children2_.Name as Name1_0_, children2_.[Order] as Order3_1_0_, children2_.ParentCategoryId as ParentCa4_1_0_ from Category this_ left outer join Category children2_ on this_.CategoryId=children2_.ParentCategoryId where this_.Name=? order by Order asc

HQL looks for property in wrong class and reports "could not resolve property"
------------------------------------------------------------------------------
Key: HHH-3300

could not resolve property: groupMembers of: projman.Project
[SELECT it.project.color AS col1 FROM projman.Deficienta def JOIN def.item it WHERE exists (FROM it.project.participants grp JOIN grp.groupMembers p WHERE p=:principal )
)) ORDER BY it.end]
the problem is, groupMembers is not a property of projman.Project, but a bag in projman,Principal.
as soon as I replace the it.project.color projection with e.g. it.start (i.e. i don't make any other join with projman.Project), the query works.
the original query is actually more complicated but i reduced my test to the above for simplicity. rewriting the query without subqueries is not an option.
i paste the relevant (generated) mappings.

I applied the (JPA) @OrderBy annotation to a collection of entities belonging to an entity class (named SampleDerived in the attached sample code) of the same type (i.e., the class has a one-to-many parent-child relationship to itself). The property name passed as the argument to the @OrderBy annotation refers to a property of the base class (named SampleBase in the example), which employs the "JOINED" inheritence strategy.
When I attempted to access the collection of a persisted instance of the entity class (in the example, this is accomplished by calling SampleServiceImpl.createSample() followed by calling SampleServiceImpl.findChildren() against the return value), the following (root cause) exception is generated:

I verified (using MySQL Administrator) that the SampleBase.timestamp column does, in fact, exist. According to the org.hibernate.SQL log, the offending SQL statement looks like this:
select children0_.parent_id as parent2_1_, children0_.id as id1_, children0_.id as id5_0_, children0_1_.timestamp as timestamp5_0_, children0_.parent_id as parent2_6_0_ from SampleDerived children0_ inner join SampleBase children0_1_ on children0_.id=children0_1_.id where children0_.parent_id=? order by SampleBase.timestamp asc
I believe the problem is that MySQL 5 requires that the alias for the base class table used in the FROM clause (children0_1_ in this case) be used in the ORDER BY clause, instead of the actual name of the base class table. After browsing various MySQL discussions, it appears this is new to MySQL 5 (versus 4 or earlier) and was done in order to be more standards compliant.
It's unclear to me whether this affects Hibernate Core or is limited to EntityManager. I'll try to narrow down the problem further as time permits (which it isn't likely to do any time soon).
