marcin muras commented on HHH-1523:
-----------------------------------
It is shame that project like Hibernate have so much annoying and not resolved bugs.
In reality such bugs makes Hibernate impossible to use in strategic systems with lot of users, data etc.where 2nd. l. cache is indispensable.
Why this bug is not assigned to anybody ?

> I have two domain objects - Employee and Department - and there is a 1:N relationship from Department to Employee. When I join fetch an Employee with its Department, without query cache enabled, it works fine. If I enable query cache for this same query, it bombs with a LazyInitializationException.
> Notes:
> 1) We get this error only if query cache is enabled.
> 2) We observed the same behaviour on both oscache and ehcache
> 3) Calling Hibernate.initialize() explicitly after firing the HQL seems to work. The initialization does not fire an extra query though (it seems to pick it from the cache).
> 4) Setting "lazy=false" on the "many-to-one" mapping also works. However, it wouldn't be acceptable.

[Hibernate-JIRA] Updated: (HHH-1930) QuerySyntaxException "with-clause expressions did not reference from-clause element to which the with-clause was associated"
by Mike Ressler (JIRA)
[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-1930?page=c... ]
Mike Ressler updated HHH-1930:
------------------------------
Attachment: HibernateTestCase.zip
Gail Badner asked for a test case showing this error. I've attached what I generated. I modified the Hibernate tutorial application a bit, but its structure should be familiar to anyone who's walked through the Hibernate tutorial. You'll need to start the HSQLDB just as you do in the tutorial before you run `ant test` to execute the test case.
I'm also encountering the same exception during development of one of my applications. I have a workaround with SQL, but I'd rather not use it. Should I rebuild Hibernate with this exception removed? Or is that going to mask a much deeper rooted problem that I'll happily plow through later?
Thanks for the advice.

---------------------------------------
Hi,
/**
* Cierra la cession;

*/
public static void closeSession() {
try {
Session s = getSession();
log.debug("Take session from thread");
if ((s != null)) {
log.debug("Closing session");
s.close();
}
} catch (HibernateException ex) {
log.error("Error closing session session - " + ex.getMessage());
throw new DCMHibernateException(ex);
}
}
While closing the session please nullify the Session present in the ThreadContext .
This will help you.

Key: HSEARCH-221
URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-221
Project: Hibernate Search
Issue Type: Improvement
Affects Versions: 3.0.1.GA
Reporter: Kenneth Christensen
Attachments: AddLuceneWork.java, DocumentBuilder.java, Flyer.java, LuceneWorker.java, TestBean.java
I'm writing a multi-language application and I have choose to use Hibernate Search.
But it looks like Hibernate Search have some limitations in multi-language applications.
I need to use the SnowballAnalyzer and create the instance at runtime because I only know the language at runtime.
It really looks like Hibernate Search don't support runtime created analyzers for entity instances.
I have extended Hibernate Search to support the above issue - maybe you could include the code in Hibernate Search or implement something similarly.
I really need this feature/improvement :-)
Please see attached files.
Flyer - Entity used in test
TestBean - SessionBean used in test
org.hibernate.search.backend.impl.lucene.LuceneWorker - Added code to support entity instance analyzer, see performWork(AddLuceneWork work, DirectoryProvider provider) and add(Class entity, Serializable id, Document document, DirectoryProvider provider, Analyzer analyzer).
org.hibernate.search.backend.AddLuceneWork - Added code to support analyzer.
org.hibernate.search.engine.DocumentBuilder - Added code to support entity instance analyzer, see addWorkToQueue(Class entityClass, T entity, Serializable id, WorkType workType, List<LuceneWork> queue, SearchFactoryImplementor searchFactoryImplementor).
