Issue with greedy loading of associations (default-lazy=false )
---------------------------------------------------------------
Key: HHH-3854
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3854
Project: Hibernate Core
Issue Type: Bug
Components: envers
Environment: Hibernate - core 3.4.0-SNAPSHOT, Hibernate-envers (from trunk)
Reporter: Amar Singh
Attachments: greedy-loading.zip
I have an Entity GP which has a many to one association to entity CA.
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="org.hibernate.envers.test.integration.onetoone.bidirectional" default-lazy="false">
<class name="BidirectionalRefIngPK" table="BIDIRECTIONAL_REFERENCING_ENTITY">
<id name="id" type="long" column="BIDIRECTIONAL_REFERENCING_ID" >
<generator class="native"/>
</id>
<property name="data"/>
<many-to-one name="reference" cascade="save-update" class="BidirectionalRefEdPK" column="BIDIRECTIONAL_REFERENCED_ID"/>
</class>
<class name="BidirectionalRefEdPK" table="BIDIRECTIONAL_REFERENCED_ENTITY">
<id name="longId" type="long" column="BIDIRECTIONAL_REFERENCED_ID">
<generator class="native"/>
</id>
<property name="data"/>
</class>
</hibernate-mapping>
With this when I load a previous version of BidirectionalRefIngPK, the loading mechanism tries to create a proxy for BidirectionalRefEdPK, but in my case lazy is false so an internal call to createProxy will return NULL hence .
This happens in ToOneIdMapper.java in method mapToEntityFromMap around line 82, which then internally calls for AbstractEntityTuplizer.java line 395 for getProxyFactory() ending in NULL pointer exception because proxy factory is null as mine is a greedy loading.
TO REPRODUCE
~~~~~~~~~~~~~
Please find a zipped folder attached. The zipped file has 4 files:
- GreedyLoading.java (actual testng test case)
- BidirectionalRefEdPK.java (Entity 1)
- BidirectionalRefIngPK.java (Entity 2)
- greedyloading.hbm.xml
Please place the three java files in its package (org.hibernate.envers.test.integration.onetoone.bidirectional), couldn't find the right package so created test case accordingly. Put the greedyloading.hbm.xml in src/test/resources.
Now when testng runs GreedyLoading.java you should see NPE.

[Hibernate-JIRA] Created: (HHH-6913) QuerySyntaxException for valid JPQL query using the IN operator
by Luis Fernando Planella Gonzalez (JIRA)
QuerySyntaxException for valid JPQL query using the IN operator
---------------------------------------------------------------
Key: HHH-6913
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6913
Project: Hibernate Core
Issue Type: Bug
Components: query-hql
Affects Versions: 3.6.9
Environment: Hibernate 3.6.9, MySQL 5.1
Reporter: Luis Fernando Planella Gonzalez
The following query, which is valid JPQL:
select person
from Person person
where person.id is not null and (person.category is null or person.category in :a1)
Generates the following error:
org.hibernate.hql.ast.QuerySyntaxException: unexpected AST node: {vector} [select person
from entities.Person person
where person.id is not null and (person.category is null or person.category in :a10_, :a11_)]
The in clause is not correct.
Note that if removing the 'person.id is not null and' part, the query works. Here is the working example:
select person
from Person person
where person.category is null or person.category in :a1
So, the closing parenthesis must be confusing the IN clause handling.
