Problem with case sensitive column and tables names and Identity mapping with postgreSQL
----------------------------------------------------------------------------------------
Key: HHH-1994
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1994
Project: Hibernate3
Type: Bug
Components: core
Versions: 3.1.3
Environment: Hibernate 3.1.3, Java 1.5.0_07 (sun) windos and linux ( 32 & 64 bit). POstgres SQL 8.1 Windows and linux
Reporter: Alex Samad
Whilst trying to insert into a table with a primary key (ID mapping) which has a identity generator. And the columns and/or the table has been defined with case sensitivey ie back ticks.
It fails to get the next serial number and thus fails any inserts.
The problem lies in dialect/PostgreSQLDialect.java
public String getIdentitySelectString(String table, String column, int type) {
return new StringBuffer().append("select currval('")
.append(table)
.append('_')
.append(column)
.append("_seq')")
.toString();
}
table is inclosed in quotes and column is inclosed in quotes which gives a name like
"table"_"Column"_seq - which fails
I would suggest a fix is to test each of table or column for " and if it exist then to strip it of both of table and column and encluse the whole name in "". This mighe break some old code where say the table is coded in case insensitive table name and case sensitive column key.
Sorry not much of a java programmer.

Entity1 has a property e2 which references Entity2. This property is defined as follows.
@ManyToOne(fetch = FetchType.LAZY, optional = false)
private Entity2 e2;
If you have an instance e1 of Entity1 which has not initialized property e2 and you merge e1 to the EntityManager within a transaction, then you get the following exception during commit:

[Hibernate-JIRA] Created: (HHH-2007) Hibernate doesn't support optional one-to-one associations
by Andrei Iltchenko (JIRA)
Hibernate doesn't support optional one-to-one associations
----------------------------------------------------------
Key: HHH-2007
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2007
Project: Hibernate3
Type: Bug
Components: core
Versions: 3.2.0.cr2
Reporter: Andrei Iltchenko
Hibernate doesn't properly support optional one-to-one associations, e.g. Person (0..1) -- (0..1) Passport.
The Hibernate books and reference all talk of two ways of mapping one-to-one associations:
1. using a many-to-one fk association with a unique constraint on the fk;
2. using a pk association.
the trouble with both of them is that they enforce the mandatory property of an association end, which sometimes is not desirable. The first way enforces the mandatory property with the uniqueness constraint on the fk, the other by using the fact that one table's pk is its fk.
I tried to see if I could adapt the 1st way of representing one-to-ones to
support optional association ends. What I did was simply remove the unique and not null constrains from DDL generated (without removing it it would be impossible to have a Person record that doesn't reference a Passport record):
from
CREATE TABLE Person (
PassUniqueId VARCHAR (32) NOT NULL,
version INTEGER NOT NULL,
uniqueId VARCHAR (32) NOT NULL,
name VARCHAR (40) NULL,
PRIMARY KEY (uniqueId),
UNIQUE(PassUniqueId),
FOREIGN KEY (PassUniqueId) REFERENCES Passport (uniqueId)
);
to
CREATE TABLE Person (
PassUniqueId VARCHAR (32) NULL,
version INTEGER NOT NULL,
uniqueId VARCHAR (32) NOT NULL,
name VARCHAR (40) NULL,
PRIMARY KEY (uniqueId),
FOREIGN KEY (PassUniqueId) REFERENCES Passport (uniqueId)
);
but leave the uniqueness attribute in the mapping file:
<many-to-one
name="pass"
class="application.business.logic.Passport"
cascade="save-update,merge"
unique="true"
>
<column name="PassUniqueId"/>
</many-to-one>
The resulting solution worked fine and I was able to create instances of Person not linked to a Passport. However Hibernate didn't succed in keeping the association from degrading into a many-to-one. It enabled me to create two Persons linked with the same Passport:
PASSUNIQUEID | VIRSION | UNIQUEID | Name
================================================
0d8b3919fffff | 1 | 0d5fb1dcfff | John
0d8b3919fffff | 0 | 10fd07bdfff | Sam
A subsequent attempt at retrieving such Persons with Hibernate failed:
org.hibernate.HibernateException: More than one row with the given identifier was found: 0d8b3919ffffffd60151e135b6da0164, for class: application.business.logic.Passport.
Hibernate should be able to impose the single end property of such associations without relying on the underlying RDBMS engine and never allow them to degrade to many-to-ones.

I found this problem:
If I create new object 'o1', which associate another persistent object 'o2' and by calling saveOrUpdate Hibernate throws PropertyValueException,
then when I corresct this property and try call saveOrUpdate in another session (in which 'o2' was not saved or loaded) Hibernate throws TransientObjectException.
Please see attached code :-)

[Hibernate-JIRA] Created: (EJB-225) EntityManager.find infinite loop related to ANN-381
by John Schneider (JIRA)
EntityManager.find infinite loop related to ANN-381
---------------------------------------------------
Key: EJB-225
URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-225
Project: Hibernate Entity Manager
Type: Bug
Environment: Hibernate Annotations 3.2.0.cr2
Hibernate EntityManager 3.2.0.cr2
Hibernate Core 3.2.0.cr4
Reporter: John Schneider
Attachments: Test.zip
I've tested the fix for ANN-381 and found that the improvement is not working correctly with the Entity Manager, specifically the find method. When calling the find method on a OneToMany collection mapped by a field in a primary key class, the Entity manager goes into an infinite loop of selecting records.
Please note that a workaround is to replace the entity managers find method with a query, such as this:
Query query = entityManager.createQuery("select c from Card c where c.id = :id");
query.setParameter("id", id);
return (Card) query.getSingleResult();
However, this workaround doesn't work if you have other entities that relate to something like the Card entity, shown below. I'll expand on the example code from ANN-381 to show the problem of infinite looping when trying to load the related collection.
@Entity
public class Card implements Serializable {
@Id
private String id;
@OneToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER, mappedBy = "primaryKey.card")
private Set<CardField> fields;
public Card(String id) {
this();
this.id = id;
}
Card() {
fields = new HashSet<CardField>();
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public void addField(Card card, Key key) {
fields.add(new CardField(card, key));
}
}
@Entity
public class CardField implements Serializable {
@EmbeddedId
private PrimaryKey primaryKey;
CardField(Card card, Key key) {
this.primaryKey = new PrimaryKey(card, key);
}
CardField() {
}
}
@Embeddable
public class PrimaryKey implements Serializable {
@ManyToOne(optional = false)
private Card card;
@ManyToOne(optional = false)
private Key key;
public PrimaryKey(Card card, Key key) {
this.card = card;
this.key = key;
}
PrimaryKey() {}
}
@Entity
public class Key implements Serializable {
@Id
private String id;
public Key(String id) {
this.id = id;
}
Key() {
}
}
>From what I can tell, this maps fine with the correct Hibernate libs and JBoss EJB Embeddable Alpha 9. However, the Entity Manager must be creating bad query code or something with similar results to having bad queries. I've testing with the following DAO:
@Stateless
public class CardDAOBean implements CardDAOLocal {
@PersistenceContext
private EntityManager entityManager;
public void createCard(Card card) {
entityManager.persist(card);
}
public Card findCard(String id) {
return entityManager.find(Card.class, id);
}
public void createKey(Key key) {
entityManager.persist(key);
}
}
The Test class:
public class EJBTest {
private Card card;
private Key key;
public static void main(String[] args) {
TestRunner.run(suite());
}
public static junit.framework.Test suite() {
TestSuite suite = new TestSuite("Test for ANN-381");
suite.addTest(new JUnit4TestAdapter(EJBTest.class));
// setup test so that embedded JBoss is started/stopped once for all
// tests here.
TestSetup wrapper = new TestSetup(suite) {
protected void setUp() {
startupEmbeddedJboss();
}
protected void tearDown() {
shutdownEmbeddedJboss();
}
};
return wrapper;
}
@Before
public void setup() {
card = new Card("cardId");
key = new Key("keyId");
card.addField(card, key);
}
@Test
public void persist() throws Exception {
InitialContext ctx = getInitialContext();

CardDAOLocal.createKey(key);

[Hibernate-JIRA] Created: (HHH-1989) Deleted object remains referenced in 2nd level cache collections
by Justin Haddad (JIRA)
Deleted object remains referenced in 2nd level cache collections
----------------------------------------------------------------
Key: HHH-1989
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1989
Project: Hibernate3
Type: Bug
Components: core
Versions: 3.2.0.cr2
Environment: Spring 1.2.8, Hibernate 3.2, Postgres 8.0.3
Reporter: Justin Haddad
This problem seems identical to issue NH-678. I have enabled caching for an one-to-many association. I use Ehcache. I have a test in which I load the parent object along with its collection. Both the parent and the collection wind up in the 2nd level cache. I then delete an object that is in the collection, not by removing it from the collection, but rather by doing a delete on the object itself. After deleting, I try to reload the parent and get the following exception (User#3102 is the deleted object):
aused by: org.hibernate.ObjectNotFoundException: No row with the given identifier exists: [com.bluenotenetworks.common.management.sm.User#3102]

(continues on)
I stepped through the code in the debugger and can see that the object's ID (3102 in this case) remains in the cached collection even after the deletion.

[Hibernate-JIRA] Created: (HHH-2041) Update with unaltered natural-id fails
by Jim Pease (JIRA)
Update with unaltered natural-id fails
--------------------------------------
Key: HHH-2041
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2041
Project: Hibernate3
Type: Bug
Components: core
Versions: 3.1.3
Environment: hibernate-3.1.3, mysql-4.1.12
Reporter: Jim Pease
This may be a duplicate of http://opensource.atlassian.com/projects/hibernate/browse/HHH-1574.
Getting following error:
caused by: org.hibernate.HibernateException: immutable natural identifier of an instance of edu.syr.lsb.gmt.impl.LinkImpl was altered
at org.hibernate.event.def.DefaultFlushEntityEventListener.checkNaturalId(DefaultFlushEntityEventListener.java:80)
at org.hibernate.event.def.DefaultFlushEntityEventListener.getValues(DefaultFlushEntityEventListener.java:155)
at org.hibernate.event.def.DefaultFlushEntityEventListener.onFlushEntity(DefaultFlushEntityEventListener.java:106)
at org.hibernate.event.def.AbstractFlushingEventListener.flushEntities(AbstractFlushingEventListener.java:195)
at org.hibernate.event.def.AbstractFlushingEventListener.flushEverythingToExecutions(AbstractFlushingEventListener.java:76)
at org.hibernate.event.def.DefaultFlushEventListener.onFlush(DefaultFlushEventListener.java:26)
...
This is occurring without modifications to the natural identifier, which is mapped as follows:
<natural-id>
<property name="activityRef" column="ACTIVITY_REF" length="255" not-null="true" />
<many-to-one name="goal" class="GoalImpl" column="GOAL_ID" not-null="true" cascade="none" />
</natural-id>
