[Hibernate-JIRA] Created: (HHH-3512) Registration of IdentifierGenerators (short naming)
by Steve Ebersole (JIRA)
Registration of IdentifierGenerators (short naming)
---------------------------------------------------
Key: HHH-3512
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3512
Project: Hibernate Core
Issue Type: New Feature
Components: core, metamodel
Reporter: Steve Ebersole
Assignee: Steve Ebersole
Fix For: 3.4, 4.x
Another way to look at this is to allow configuration of IdentifierGeneratorFactory.
Either allow explicit registration under a short name in config:
<identifier-generator name="sequence-style" class="org.hibernate.id.enhanced.SequenceStyleGenerator"/>
or via an explicit contract:
public interface Registerable {
public String getRegistrationName();
}
public class SequenceStyleGenerator implements IdentifierGenerator, Registerable {
...
public String getRegistrationName() {
return "sequence-style";
}
}
The second, while certainly more verbose, can be used applied to other situations where we want to allow registration moving forward (types, property-accessor, etc).

[Hibernate-JIRA] Created: (HHH-2764) EntityType.deepCopy needs to copy for EntityType.DOM4J
by Alan Krueger (JIRA)
EntityType.deepCopy needs to copy for EntityType.DOM4J
------------------------------------------------------
Key: HHH-2764
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2764
Project: Hibernate3
Issue Type: Bug
Affects Versions: 3.2.2
Environment: Hibernate 3.2.2
Reporter: Alan Krueger
Using DOM4J with a set of composite-elements that contains a many-to-one. When loading this from the database, the many-to-one piece of the composite-element is disappearing from the XML. I can see the collection being built and the properties on the elements of the collection being set, but the many-to-one property disappears after that.
Investigating this, it looks like when PersistentElementHolder.getSnapshot is called and a deepCopy is performed, the EntityType.deepCopy method returns the value to be copied rather than copying it. This interacts poorly with the DOM4J tree, since each Element can only have a single Element parent. When the properties are set on this, a detach is performed that yanks the original element out of its parent.

[Hibernate-JIRA] Created: (HSEARCH-349) Allow custom Loader in FullTextQueryImpl
by Julien Kronegg (JIRA)
Allow custom Loader in FullTextQueryImpl
----------------------------------------
Key: HSEARCH-349
URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-349
Project: Hibernate Search
Issue Type: New Feature
Components: query
Affects Versions: 3.1.0.GA
Environment: Hibernate 3.3.1.GA, DB2
Reporter: Julien Kronegg
Priority: Minor
When doing an native SQL query containing join and other complicated stuff, one can get a List<MyObject> using the following code:
List<MyObject> list = entityManager.createNativeQuery("SELECT ...", MyObject.class).getResultList();
The MyObject class is an JPA Entity, but is not connected to a database table: the MyObject instance is reconstructed automatically by mapping the ResultSet column names and the MyObject field names.
This object list can be indexed using Hibernate Search (by adding @Indexed and @Field annotations to the MyObject entity). When doing an Hibernate Search query, the FullTextQueryImpl.list() method uses a Loader which try to load the MyObject entities from the database by a query such as "SELECT ... FROM MYOBJECT where id in (?,?,?,..)" (where the list of "?" is the list of identifiers returned by Lucene).
Here, we have a problem: the MYOBJECT table does not exist and obviously an exception is raised. The desired result would be for example to look into the initial List<MyObject> "list" instead of asking to the database.
This functionnality could be done very simply by adding a "Loader customLoader" field (with its public getter/setter) in the org.hibernate.search.query.FullTextQueryImpl class and by modifying the getLoader() method such as:
private Loader getLoader(Session session, SessionFactoryImplementor sessionFactoryImplementor) {
if (customLoader!=null) {
customLoader.init(session, sessionFactoryImplementor);
return customLoader;
}
...
}
After this modification, the programmer can design its own Loader which implements whatever loading strategy. For the example above, the Loader.load(EntityInfo[]) method may looks for each EntityInfo.id in the initially obtained List<MyObject> "list".
There is a workaround: copy the full source code of FullTextQueryImpl and add the described modifications.

[Hibernate-JIRA] Created: (HHH-2459) Problem with <parent> for 2+ levels of components
by Kevin Bragh (JIRA)
Problem with <parent> for 2+ levels of components
-------------------------------------------------
Key: HHH-2459
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2459
Project: Hibernate3
Type: Bug
Components: core
Versions: 3.2.2
Environment: Hibernate 3.2.2, Tested on PostgreSQL and HSQL
Reporter: Kevin Bragh
Attachments: test.zip
I have tested several scenarios similar to the above, and I have searched and posted to the forum with no response.
I have attached the faulty code to the thread.
I have a main class (A) with 3 components recusively included as follows:
A -> B -> C <-> D
In the case above, D has a <parent> property to C.
While loading an instance of A, it seems that D.setC(...) is called with the value of the main class A, and not of parent C.
I don't know if this is a bug, or if parent is not recusively supported.
Any help is appreciated.
Thks, K.
NB: I have tried many different examples (with list and composite-element, etc.) and they all fail with 2+ levels of recursion.

[Hibernate-JIRA] Created: (HSEARCH-183) @IndexedEmbedded(prefix="") should either be forbidden or fixed with duplicate ID fields
by Stephane Epardaud (JIRA)
@IndexedEmbedded(prefix="") should either be forbidden or fixed with duplicate ID fields
----------------------------------------------------------------------------------------
Key: HSEARCH-183
URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-183
Project: Hibernate Search
Issue Type: Improvement
Components: mapping
Affects Versions: 3.0.1.GA
Reporter: Stephane Epardaud
If all my entities have their ID property named "id" and they use @IndexedEmbedded(prefix="") then there will be several fields named "id" per document.
This results in very unfortunate behaviour when indexes are updated because this id is then used by HS to remove Lucene documents, so instead of removing only the one document we are updating, HS removes all documents whose ID have been embedded in the index.
We use prefix="" in order to accumulate embedded entities' "text" fields into the root entity so that we can search on any "text" field, embedded or not. This is required because there seems to be no support for a term wildcard such as "*.text:foo" which would search on any term ending by ".text" for the string "foo".
Either prefix="" is supported, and this behaviour should be changed, or at the very least trigger a visible warning, or it is not supported and it should be documented and an exception should be thrown.
Since it is behaviour I need, I favour supporting it, so I've patched DocumentBuilder to store the ID of the root entity in a special field like _hibernate_class, so that when we update the index only the appropriate entity index document is removed. This works well, but has the side-effect of ignoring the name of the ID as specified in @DocumentId.
An alternative would be to still store the root ID is a "special" field, and keep storing the ID under a field name as specified by the user. As long as we only use the "special" ID for index updating all will work well.
I can produce both patches and documentation if you agree (and choose).
