[Hibernate-JIRA] Created: (HBX-939) Composite IDs and many-to-many relationships
by Markus Kramer (JIRA)
Composite IDs and many-to-many relationships
--------------------------------------------
Key: HBX-939
URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-939
Project: Hibernate Tools
Issue Type: Bug
Affects Versions: 3.2beta9
Environment: Hibrnate 3.2.1, Postgresql 8.1.8
Reporter: Markus Kramer
Attachments: B.hbm.xml, testdb.sql
The detection of many-to-many relationships doesn't work correctly if the primary key of one of the involved tables consists of more than one field.
An example:
One of two tables (table 'A') of a many-to-many relationship has a primary key consisting of two attributes (id1 and id2).
The generated B.hbm.xml for the table 'B' contains this:
<set name="as" inverse="true" table="a_b">
<key>
<column name="b_id" not-null="true" />
</key>
<many-to-many entity-name="test.A">
<column name="a_id1" not-null="true" />
</many-to-many>
</set>
But there should be another entry for the referenced primary key:
<column name="a_id2" not-null="true" />
The SQL code for the used tables and the complete B.hbm.xml are attached.

Search fails to start when core uses XML mappings making use of entity-name attribute
-------------------------------------------------------------------------------------
Key: HSEARCH-444
URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-444
Project: Hibernate Search
Issue Type: Bug
Components: mapping
Affects Versions: 3.1.0.GA
Reporter: Sanne Grinovero
Assignee: Emmanuel Bernard
Fix For: 3.2.0.Beta2
As described on forums: https://forum.hibernate.org/viewtopic.php?f=9&t=993687
classes mapped using XML on hibernate core, like
classes starting with:
<class name="com.mydomain.myapp.AnswerImpl" table="answer"
entity-name="Answer">
cause:

This was reported on 3.1.0.GA but I guess it affects all releases.
There's a "test WAR" in the forums, going to ask for a testcase.

[Hibernate-JIRA] Created: (HHH-6925) Unnecessary .toLowercase() in SQLServer2005 dialect
by Hasan Ceylan (JIRA)
Unnecessary .toLowercase() in SQLServer2005 dialect
---------------------------------------------------
Key: HHH-6925
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6925
Project: Hibernate Core
Issue Type: Bug
Components: core
Affects Versions: 4.0.0.Final
Environment: SQL Server with Turkish CI
Reporter: Hasan Ceylan
Priority: Blocker
in getLimitString(String, boolean), the original query is transformed to lower case. with non Turkish locale on the AS Server, this is lowered by latin rules.
However, SQL Server as its locale is Turkish, cannot match TURKISH_TABLE / TURKISH_COLUMN with turkish_table / turkish_column raising "object / column not found" exception.
For detailed info on how 'I / i' handled in Turkish locale please refer to http://www.java2s.com/Tutorial/CSharp/0440__I18N-Internationalization/tur...
Very simple fix is to remove the toLowerCase() from getLimitString(String, boolean). If that serves a purpose then lowering should be made based on SQL Server locale of the current user, connection, database (I am not sure).
Regards,
Hasan Ceylan

[Hibernate-JIRA] Created: (HHH-3129) Null Role in PersitentCollection during a onCollectionRecreate() in an Interceptor
by Jose CHILLAN (JIRA)
Null Role in PersitentCollection during a onCollectionRecreate() in an Interceptor
----------------------------------------------------------------------------------
Key: HHH-3129
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3129
Project: Hibernate3
Issue Type: Bug
Components: core
Affects Versions: 3.2.6
Environment: Any
Reporter: Jose CHILLAN
When the "onCollectionRecreate" is invoked on an Interceptor, the getRole() method returns null. After investigation,
the problem is located in the class CollectionEntry in one of its constructors and is easily solved using the patch :
public CollectionEntry(CollectionPersister persister, PersistentCollection collection)
{
// new collections that get found + wrapped
// during flush shouldn't be ignored
ignore = false;
collection.clearDirty(); //a newly wrapped collection is NOT dirty (or we get unnecessary version updates)
snapshot = persister.isMutable() ? collection.getSnapshot(persister) : null;
// -- ADDED LINE HERE --
role = persister.getRole();
collection.setSnapshot(loadedKey, role, snapshot);
}
Thanks
