[Hibernate-JIRA] Created: (HHH-3107) Error with sql generated for set of subclass A in a peer subclass B.

Error with sql generated for set of subclass A in a peer subclass B.
--------------------------------------------------------------------
Key: HHH-3107
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3107
Project: Hibernate3
Issue Type: Bug
Affects Versions: 3.2.6
Reporter: Austin Mayberry
A mapping such as the following contrived examples does not yield the expected results and causes and error:
<class name="com.foo.Foo1" table="FOO1">
<id
name="id"
type="java.lang.Integer"
column="ID"
>
<generator class="sequence" >
<param name="sequence">ID_SEQ</param>
</generator>
</id>
<discriminator column="FOO_TYPE_ID" type="java.lang.Integer"/>
<subclass name="com.foo.Foo2" discriminator-value="0">
<join table="FOO2">
<key column="ID"/>
<property
name="label"
type="java.lang.String"
column="LABEL"
not-null="true"
length="255"
/>
</join>
<subclass name="com.foo.BarOne" discriminator-value="1">
<set
name="barTwos"
inverse="true"
>
<key>
<column name="PARENT_ID" />
</key>
<one-to-many class="com.foo.BarTwo" />
</set>
</subclass>
<subclass name="com.foo.BarTwo" discriminator-value="2">
<join table="BAR">
<key column="ID"/>
<many-to-one
name="parent"
class="com.foo.BarOne"
not-null="true"
column="PARENT_ID"
/>
</join>
</subclass>
</subclass>
</class>
The sql created to populate the set "bartwos" looks like this looks like:
select
bartwos0_.PARENT_ID as PA3_1_,
bartwos0_.ID as ID1_1_,
bartwos0_.ID as ID1_52_0_,
bartwos0_.FOO_TYPE_ID as FO2_52_0_,
bartwos0_1_.LABEL as LABEL76_0_,
bartwos0_2_.PARENT_ID as PA2_87_0_
from FOO1 bartwos0_, FOO2 bartwos0_1_, BAR2 bartwos0_2_
where bartwos0_.ID=bartwos0_1_.ID
and bartwos0_.ID=bartwos0_2_.ID
and bartwos0_.PARENT_ID=?
And yields the following error message:
java.sql.SQLException: ORA-00904: "BARTWOS0_"."PARENT_ID: invalid identifier
The basic problem is that it should be looking for the property PARENT_ID on BAR2, but it is looking for it on FOO1.

[Hibernate-JIRA] Created: (HHH-2584) PersistentMap.remove() incorrect on uninitialized, non-extra-lazy map
by Daniel Wellman (JIRA)
PersistentMap.remove() incorrect on uninitialized, non-extra-lazy map
---------------------------------------------------------------------
Key: HHH-2584
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2584
Project: Hibernate3
Issue Type: Patch
Components: core
Affects Versions: 3.2.3, 3.2.2, 3.2.1
Environment: Hibernate 3.2.3 ga, MySQL 5.0.24a, for Win32
Reporter: Daniel Wellman
Attachments: persistentmap_remove.patch
This problem is nearly identical to HHH-2476: PersistentMap.put() incorrect on uninitialized, non-extra-lazy map. remove() has the same problem. See also issue HHH-2142.
The write up for HHH-2476 was so concise that I will transform it here, substituting remove() for put().
---
Essentially, an uninitialized PersistentMap loses the first remove() into it if defined as non-extra-lazy.
The underlying cause is the code in PersistentMap#remove() which attempts to readElementByIndex(). In the case of non-extra-lazy, readElementByIndex() returns the UNKNOWN marker object which is supposed to be used to signal that the delegate map is now initialized and to remove the element directly from the map. Long story short, PersistentMap#remove() does not properly check the return value from readElementByIndex() and react accordingly.

[Hibernate-JIRA] Created: (HHH-3030) NullPointerException happens in versioning

NullPointerException happens in versioning
------------------------------------------
Key: HHH-3030
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3030
Project: Hibernate3
Issue Type: Bug
Components: core
Affects Versions: 3.2.5
Environment: any
Reporter: John
Priority: Minor
Here is the stack trace:

......
The code is:
public Object next(Object current, SessionImplementor session) {
return new Integer( ( (Integer) current ).intValue() + 1 );
}
Should there be a null checking for the object "current"?

[Hibernate-JIRA] Created: (HHH-3349) SequenceStyleGenerator generates strange IDs for PostgreSQL database
by Adam Wozniak (JIRA)
SequenceStyleGenerator generates strange IDs for PostgreSQL database
--------------------------------------------------------------------
Key: HHH-3349
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3349
Project: Hibernate3
Issue Type: Bug
Affects Versions: 3.2.6
Environment: hibernate-3.2.6.ga, hibernate-annotations-3.3.1.GA, hibernate-entitymanager-3.3.2.GA, hibernate-validator-3.0.0.GA, PostgreSQL 8.3.1 on Windows box. Sun Java 6 (Win32 on Vista 32 bits).
Reporter: Adam Wozniak
Hello
I've got a standalone application using environment:
* PostgreSQL 8.3.1 (Win 32)
* hibernate-3.2.6.ga
* hibernate-annotations-3.3.1.GA
* hibernate-entitymanager-3.3.2.GA
* hibernate-validator-3.0.0.GA
I've got a PostgreSQL database sequence:
CREATE SEQUENCE t_seq
INCREMENT 10
MINVALUE 1
MAXVALUE 999999999999999999
START 11;
My entity:
@Entity
@Table(name = "T")
@org.hibernate.annotations.Entity(dynamicUpdate=true, dynamicInsert=true)
public class T
{
private long id;
@Id
@Column(unique = true, nullable = false, precision = 18, scale = 0)
@GeneratedValue(generator = "t_generator")
@GenericGenerator( name = "t_generator",
strategy = "org.hibernate.id.enhanced.SequenceStyleGenerator",
parameters = {
@Parameter(name = "sequence_name", value = "T_SEQ")
, @Parameter(name = "increment_size", value = "10")
, @Parameter(name = "optimizer", value = "pooled")
}
)
public long getId()
{
return id;
}
public void setId(long id)
{
this.id = id;
}
}
And my test application to recreate this issue:
for(int i = 0; i < 11; i++)
{
if(i == 0 || i == 10)
System.out.println("Database hit to sequence will be performed.");
T t = new T();
em.persist(t);
}
Reading this Steve Ebersole description ( http://blog.hibernate.org/2082.lace#comments ) I would expect, that I will get the following IDs:
11
12
13
14
15
16
17
18
19
20
21
But Hibernate generates:
101
102
103
104
105
106
107
108
109
110
111
Is it something wrong with my code? Or this is a issue in Hibernate?
Note please, that on the same page ( http://blog.hibernate.org/2082.lace#comments ) other person claims that it doesn't work for his configuration based on PostgreSQL.
You will find my log4j output for my test application on the end of my email.

Adam Wozniak

[Hibernate-JIRA] Created: (HHH-2295) entity-name attribute's syntax not clearly documented
by Jeremy Michael Crosbie (JIRA)
entity-name attribute's syntax not clearly documented
-----------------------------------------------------
Key: HHH-2295
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2295
Project: Hibernate3
Type: Bug
Components: documentation
Versions: 3.2.1
Environment: Windows XP/JDK 1.5/HypersonicSQL
Reporter: Jeremy Michael Crosbie
Priority: Minor
Attachments: Group.hbm.xml
Setting entity-name to a value containing a hyphen, in my case 'lender-group' causes odd behaviors seemingly only when calling get() or load(). Also in my case I am mapping a class to two different tables (attached). The first mapping has an entity name with a hyphen, the other does not. When I call load *after committing a transaction where a new entity is persisted* I get an exception (see below). The exception complains of a column called "LENDER" not existing. But once I change the entity-name to something like 'lendergroup' the problem goes away. Interestingly, the missing column complained about is the text before the hyphen, so if I name the entity 'lndr-group' it complains of a column name 'LNDR' not existing.
It almost appears if this format is assuming some sort of discriminator, but the online docs are terse when it comes to describing the entity-name field.
