PostLoad method invoked before collection initialised
-----------------------------------------------------
Key: HHH-6043
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6043
Project: Hibernate Core
Issue Type: Bug
Components: entity-manager
Affects Versions: 3.6.2
Environment: Windows 7 64-bit, hibernate 3.6.2 final, sun java 1.6 64 bit
Reporter: Setanta Mathews
Attachments: bugTestCase.rar
Hi,
I had been monitoring this bug under Jboss's https://issues.jboss.org/browse/JBAS-5474 . However the issue was recently closed.
The description for that bug was
{quote}
I have a bean with a @OneToMany relation mapping like
private List<TherapieeinheitBean> therapieeinheiten;
@OneToMany(
cascade = {CascadeType.REFRESH},
fetch = FetchType.EAGER,
mappedBy="therapiekatalog"
)
with FetchType.EAGER and a simnple @PostLoad like
@PostLoad
public void postLoad() { System.out.println("!!!!!!!!!! postLoad !!!!!!!!!!"); System.out.print("size: " + therapieeinheiten.size()); }
When an entity of this bean is loaded JBoss trows
org.hibernate.LazyInitializationException: illegal access to loading collection
at org.hibernate.collection.AbstractPersistentCollection.initialize(AbstractPersistentCollection.java:341)

at de.visiodesk.therapiekatalog.TherapiekatalogBean.postLoad(TherapiekatalogBean.java:170)
.
.
.
and prints the messages
WARN [LoadContexts] fail-safe cleanup (collections) : org.hibernate.engine.loading.CollectionLoadContext@2c8ce9<rs=Ingres-ResultSet[18523]>
WARN [CollectionLoadContext] On CollectionLoadContext#cleanup, localLoadingCollectionKeys contained [206] entries
afterwards. The PostLoad method should be called after the data was completely loaded. Is there a workaround for this Problem? I found some other ressources on the net where peole had the same problem, but I saw no resolution, no hint, no workaround.
{quote}
I can confirm that this issue still exists for the Hibernate 3.6.2 release.
The attached bugTestCase.rar contains a modified version of the test that was originally attached to the JBoss bug. I've changed it to work with spring and JPA.
Note that the attached test passes as the test is annotated with @Test(expected=PersistenceException.class)
The stack trace from the exception thrown is

[Hibernate-JIRA] Created: (HHH-6655) trim function on DB2 is broken
by Strong Liu (JIRA)
trim function on DB2 is broken
------------------------------
Key: HHH-6655
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6655
Project: Hibernate Core
Issue Type: Bug
Affects Versions: 4.0.0.CR2
Reporter: Strong Liu
For DB2 a warning message is generated by TempateRenderer which is not seen for other databases:
WARN: HHH00174:Function template anticipated 3 arguments, but 2 arguments encountered
see test _org.hibernate.ejb.criteria.CriteriaCompilingTest#testTrim_ for more details
Also the query created is different in case of DB2:
Hibernate: select replace(replace(ltrim(rtrim(replace(replace(customer0_.NAME,' ','${space}$'),?,' '))),' ',?),'${space}$',' ') as col_0_0_ from CUSTOMER_TABLE customer0_ where customer0_.NAME=? fetch first 2 rows only
and finally it fails because of above warning:
javax.persistence.PersistenceException: org.hibernate.exception.SQLGrammarException: DB2 SQL Error: SQLCODE=-313, SQLSTATE=07001
For other DBs same code generates following query and test passes:
Hibernate: select trim(BOTH ? from customer0_.NAME) as col_0_0_ from CUSTOMER_TABLE customer0_ where customer0_.NAME=? limit ?

[Hibernate-JIRA] Created: (HHH-2280) Not-Null Constraint-Violation with unidirectional one-to-many mapping
by Robert Herschke (JIRA)
Not-Null Constraint-Violation with unidirectional one-to-many mapping
---------------------------------------------------------------------
Key: HHH-2280
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2280
Project: Hibernate3
Type: Bug
Versions: 3.2.0.cr4
Environment: Hibernate 3.2.0.cr4, Oracle 10XE
Reporter: Robert Herschke
Priority: Blocker
Attachments: one-to-many-test.zip
In some cases it is neccessary to have an unidirectional one-to-many mapping, but not using Join-Tables due to a legacy database system.
So it must be possible, to have a one-to-many mapping just via a foreign-key-mapping. The Child-Object must not know the Parent-Object in this case.
It must also be possible, to pay respect to a NOT-NULL-Constraint at this foreign-key due to restrictions on legacy database systems.
Hibernate doesn't support this, but throw a NOT-NULL-Constraint Violation Exception. The documentation says, "this is unusual" - to which I want to dissent.
See the attached testcase for details, that is adopted from your "one-to-many" testcase found in the 3.2.0 sources.

[Hibernate-JIRA] Created: (HHH-4459) Query with Composite Primary Key parameter crashes when query cache is on

Query with Composite Primary Key parameter crashes when query cache is on
-------------------------------------------------------------------------
Key: HHH-4459
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4459
Project: Hibernate Core
Issue Type: Bug
Components: caching (L2)
Affects Versions: 3.3.2
Environment: Hibernate Core 3.3.2.GA, MySQL and H2
Reporter: Karol Bienkowski
I have an entity with a composite identifier (primary key) annotated with EmbeddedId:
@Embeddable
public class CompositeKey implements Serializable {
(...)
}
@Entity
public class EntityWithCompositeKey {
@EmbeddedId
public CompositeKey pk;
(...)
}
When executing query ...
FROM EntityWithCompositeKey e WHERE e.pk = :pk
... where ":pk" is bound to an instance of CompositeKey ...
query.setParamter("pk", new CompositeKey(..))
... I get the following exception:

It used to work on 3.3.1.GA but fails in 3.3.2.GA. Turning off query cache works.
The direct reason for the error is that TypedValue.value is an Object[] but ComponentType.getHashCode() expects TypedValue.value to be of CompositeKey type.
I'll attach the working test case replicating the issue in a moment.

[Hibernate-JIRA] Created: (HHH-6005) DefaultComponentSafeNamingStrategy breaks @ElementCollection of @Embeddables
by Artem Troitskiy (JIRA)
DefaultComponentSafeNamingStrategy breaks @ElementCollection of @Embeddables
----------------------------------------------------------------------------
Key: HHH-6005
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6005
Project: Hibernate Core
Issue Type: Bug
Components: core
Affects Versions: 3.5.0-Final
Reporter: Artem Troitskiy
Priority: Minor
{{DefaultComponentSafeNamingStrategy}} is incompatible with {{@ElementCollection}} of {{@Embeddable}} objects.
Given the following classes
{code:java}
@Entity
public class Foo {
@ElementCollection
private List<Bar> bars;
...
}
@Embeddable
public class Bar {
private String name;
...
}
{code}
and DefaultComponentSafeNamingStrategy as a naming strategy, Hibernate generates the schema with the following incorrect table:
bq. create table Foo_bars (Foo_id bigint not null, bars_collection&&element_name varchar(255))
{{.collection&&element.}} is an internal placeholder that should be removed before use of property name. Other naming strategies effectively remove it by using the part of property name after the last {{.}}, but {{DefaultComponentSafeNamingStrategy}} doesn't, it just replaces {{.}} with {{_}}.
Here is a workaround:
{code:java}
public class FixedDefaultComponentSafeNamingStrategy extends DefaultComponentSafeNamingStrategy {
@Override
public String propertyToColumnName(String propertyName) {
return super.propertyToColumnName(propertyName.replace(".collection&&element.", "."));
}
}
{code}
