<list-index> base attribute ignored on insert for a bidirectional association (one-to-many)
-------------------------------------------------------------------------------------------
Key: HHH-4915
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4915
Project: Hibernate Core
Issue Type: Bug
Components: core
Affects Versions: 3.5.0-CR-1, 3.3.2
Environment: Hibernate 3.3.2GA and 3.5.0-CR-1
Oracle Database
Reporter: Olivier Lafontaine
Attachments: hibernate-poc-jira.zip
My mapping looks like the following:
{code:xml}
<hibernate-mapping>
<class name="Parent">
<!-- SNIP -->
<list name="children" table="CHILD" cascade="all-delete-orphan">
<key column="ID_PARENT" not-null="true" />
<list-index base="1">
<column name="IDX" check="IDX > 0" />
</list-index>
<one-to-many class="Child" />
</list>
</class>
<class name="Child">
<!-- SNIP -->
<many-to-one name="parent" class="Parent" column="ID_PARENT"
not-null="true" insert="false" update="false" />
</class>
</hibernate-mapping>
{code}
As you can see from the mapping, we have a parent entity ({{Parent}}) referring child entities ({{Child}} using the {{children}} accessor). The index column ({{ORDER}}) is not an attribute in the child entity, so I referred to the second use case in section _6.3.3. Bidirectional associations with indexed collections_ of the reference guide to do my mapping.
Everything works except for the index base, it is always 0 based on insert. I've tried both Hibernate 3.3.2GA and the latest development version (3.5.0-CR-1), the issue can be reproduced in both.
I've joined a test case to reproduce the problem. While working on it, I realized there are updates after the inserts setting the correct index. However, we cannot change the database schema and there's a constraint on the index column enforcing a value > 0. So this issue is really important for us. I could manually handle the index values, but it would be so much easier to let Hibernate do it.
I've traced the problem and it seems that {{StatefulPersistenceContext#getIndexInParent(..)}} does not considers the index base. Why are updates necessary after the inserts? It looks to me like Hibernate could correctly set the index parameter on the insert statements.

I have a parent entity with child entities being loaded using SubSelect and eager fetching. I execute a query to retrieve all parents and get the following query which SQL Server 2005 does not support:
select
childtab0_.CONFIG_KEY as CONFIG5_23_1_,

SQL Server does not like the tuple in the where clause.

[Hibernate-JIRA] Created: (HHH-2666) subselect fetching ignores max results
by James Roper (JIRA)
subselect fetching ignores max results
--------------------------------------
Key: HHH-2666
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2666
Project: Hibernate3
Issue Type: Improvement
Components: query-hql, query-sql
Affects Versions: 3.2.1
Environment: Hibernate 3.2.1
HSQLDB 8.0
Reporter: James Roper
Priority: Minor
When maxResults is set for a query, the hibernate subselect fetching strategy ignores it. For example, I have a class entry, that has a list of comments, which are configured to use the subselect fetching strategy. You can see that in the original query, only the top ? results are fetched:
select
top ? entry0_.id as id0_,
entry0_.title as title0_,
entry0_.entry as entry0_,
entry0_.time as time0_,
entry0_.category_id as category5_0_
from
Entry entry0_
order by
entry0_.time desc
But then when it does the sub select query to lazily load the comments, this is the query it runs:
select
comments0_.entry_id as entry5_1_,
comments0_.id as id1_,
comments0_.id as id1_0_,
comments0_.time as time1_0_,
comments0_.comment as comment1_0_,
comments0_.author as author1_0_
from
Comment comments0_
where
comments0_.entry_id in (
select
entry0_.id
from
Entry entry0_
)
order by
comments0_.time desc
So, it loads every single comment in the database, even though only the comments for the top ? entries are needed. Of course, if there was no order by clause on the first query, the sub select may not return the same results, so it should probably only do this when there is an order by clause in the first query, and it should make sure it includes the order by clause in the sub select.

Need a way to specify "unsaved-value" strategy using annotations
----------------------------------------------------------------
Key: ANN-609
URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-609
Project: Hibernate Annotations
Issue Type: Bug
Environment: Hibernate 3.2.2, Hibernate-annotations 3.2.1
Reporter: Suji Suresh
Hibernate has two ways of specifying a value for primary key:
1. Assign a value before handing it over to Hibernate
2. Have Hibernate generate the value before persisting
In my project I have objects of both of the above specified types. In other words I assign value for the primary key for some the objects (lets call these objects "assigned") and for others I have Hibernate generate the value before persisting (lets call these objects "generated"). Since Hibernate annotations does not support "unsaved-value", I do not have a way of specifying "unsaved-value" strategy. While my "generated" objects work perfectly with Hibernate's default "unsaved-value" strategy, I see wrong (but expected) behaviour when I try to persist an "assigned" object that is already present in the database in that, I get StaleStateException instead of DataIntegrityViolationException

[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.

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.
