Content assist doesn't work when an entity alias is not preceded by whitespace
------------------------------------------------------------------------------
Key: HBX-895
URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-895
Project: Hibernate Tools
Type: Bug
Versions: 3.2beta8
Reporter: Joseph Marques
In an HQL editor:
If I type - "count(col." - and press ctrl+space, I don't get the content assist for col
If I type - "count( col." - and press ctrl+space, I do
Similarly,
If I type - "select a,b." - and press ctrl+space, I don't get the content assist for b
If I type - "select a, b." - and press ctrl+space, I do
It's pretty clear that the lexing is a little bit too tight here, and that for better usability it should be relaxed. The second case isn't as big a deal as the first (because I don't know a single person that doesn't comma-space delimit the select clause, but I'm thinking that some people that don't realize that they have to put a space in front of it might think that the tools simply can't auto-complete inside functions.

[Hibernate-JIRA] Created: (HHH-3445) Single Table Inheritence Broken for non table-unique keys
by Todd Tidwell (JIRA)
Single Table Inheritence Broken for non table-unique keys
---------------------------------------------------------
Key: HHH-3445
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3445
Project: Hibernate3
Issue Type: Bug
Environment: Hibernate Core: 3.2.6.ga
Hibernate Annotations: 3.3.1.ga
Hibernate EntityManager: 3.3.2.ga
DB2 Linux 9.1
Reporter: Todd Tidwell
I have an interesting mapping case that is causing me some very odd low-level errors. In this particular case, I'm working with a table that contains multiple objects and I can use a DiscriminatorColumn to differentiate. However, the "primary key" for the child objects is not guaranteed to be uniqe table-wide. For example, DiscriminatorColumn value '013' may have a unique-key value of 'A', DiscriminatorColumn '014' may have the same unique-key value.
To map this, I created a base class, gave it the DiscriminatorColumn annotation, and then extended it with my various types.
Here are the classes:
@Entity
@Table(name="WTTBLE")
@DiscriminatorColumn(name="PTBLE")
public abstract class MetaData
{
@Id
@Basic(fetch=FetchType.EAGER)
@Column(name="PCODE", nullable=false, insertable=false, updatable=false)
private String code = null;
@Basic(fetch=FetchType.EAGER)
@Column(name="DEF", nullable=false, insertable=false, updatable=false)
private String value = null;
....
}
@Entity
@DiscriminatorValue(value = "015")
public class AddressType
extends MetaData
{
// No fields here, they're all mapped in MetaData
}
@Entity
@DiscriminatorValue(value = "016")
public class CustomerType
extends MetaData
{
// No fields here, they're all mapped in MetaData
}
Now, this works great until they both have the same value for the "code" property. At that point, I get the following logging and exception:
org.hibernate.impl.SessionImpl - initializing proxy: [com.wiley.permissions.domain.persistence.wintouch.metadata.AddressType#A]
....
org.hibernate.event.def.DefaultLoadEventListener - load request found matching entity in context, but the matched entity was of an inconsistent return type; returning null
....
javax.persistence.EntityNotFoundException: Unable to find test.AddressType with id A
at org.hibernate.ejb.Ejb3Configuration$Ejb3EntityNotFoundDelegate.handleEntityNotFound(Ejb3Configuration.java:107)
at org.hibernate.proxy.AbstractLazyInitializer.checkTargetState(AbstractLazyInitializer.java:79)
at org.hibernate.proxy.AbstractLazyInitializer.initialize(AbstractLazyInitializer.java:68)

at org.hibernate.proxy.pojo.cglib.CGLIBLazyInitializer.invoke(CGLIBLazyInitializer.java:150)
at test.AddressType$$EnhancerByCGLIB$$16d4c983.getValue(<generated>)
After some serious research, I found that org.hibernate.engine.StatefulPersistenceContext is returning the wrong object from it's getEntity method. It's returning a CustomerType object, which was added to the session's cache after the address type. On furthur examination, this seems to be because org.hibernate.engine.EntityKey.equals() is returning the same value for both objects. EntityKey's code for lines 95 -99 is:
public boolean equals(Object other) {
EntityKey otherKey = (EntityKey) other;
return otherKey.rootEntityName.equals(this.rootEntityName) &&
identifierType.isEqual(otherKey.identifier, this.identifier, entityMode, factory);
}
Examination of the values of EntityKey for my objects show that rootEntityName for both objects is test.MetaData. That means that this method is going to return true. That, in turn, means that StatefulPersistenceContext's entitiesByKey HashMap is going to return the first one that equals the one passed into the get() method.

[Hibernate-JIRA] Created: (HHH-3119) LazyInitializationException from 3.2.4+ onward
by Nick de Graeve (JIRA)
LazyInitializationException from 3.2.4+ onward
----------------------------------------------
Key: HHH-3119
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3119
Project: Hibernate3
Issue Type: Bug
Components: core
Affects Versions: 3.2.6, 3.2.5, 3.2.4.sp1, 3.2.4
Reporter: Nick de Graeve
Priority: Blocker
We used to run JBoss 4.0.4.GA and we included Hibernate 3.2.0CR2 ourselves. Now we migrated to JBoss 4.2.2.GA and in that one Hibernate 3.2.4.sp1 is included by default.
Unfortunately, we're getting LazyInitializationException when the object graph is more than 2 levels deep.
E.g. RtTask --[OK]--> Priority --[FAIL]--> DictionaryEntry
We haven't changed anything to our beans or configuration files.
I did find out that v.3.2.4 is the first version that throws the exception.

Name and version of the database you are using: MySQL 5.0.33
The generated SQL (show_sql=true):
Hibernate: select b_.id, b_.aId as aId1_, b_.cId as cId1_ from B b_ where b_.id=?
Hibernate: insert into C (id) values (?)
Hibernate: insert into A (id) values (?)
Hibernate: insert into B (aId, cId, id) values (?, ?, ?)
Hibernate: select a0_.id as id0_0_ from A a0_ where a0_.id=?
Hibernate: select bs0_.aId as aId1_, bs0_.id as id1_, bs0_.cId as cId1_, bs0_.id as id1_0_, bs0_.aId as aId1_0_, bs0_.cId as cId1_0_ from B bs0_ where bs0_.aId=?
I've been having a confusing problem shown above, whereby A has a Map of Bs indexed using the id from an association with C. This Map is inversely mapped for A and with 'Cascade Delete Orphan'. In the second opened session above, where B is removed from A's Map and thus orphaned, B will not be deleted. I have observed B is only deleted if I either set 'lazy="false"' for A's Map or make an interaction with A's Map in the code (before B's removal) like 'a.getBs().get(cId)'. I suspect the lazy intializer is not initializing correctly in the above scenario.
The above scenario does not happen if A's Map is not inversely mapped but B's many-to-one with A is.
Can somebody shed some light on whether this is me using Hibernate incorrectly or is a bug?
