If the project is renamed so it does not contain any <SPACE> characters anymore it works fine.
This problem did not occur in Hibernate Tools 3.2 Beta11

[Hibernate-JIRA] Created: (HHH-2855) Error during a entity collection loading - wrong SQL query generation - missing discriminator condition in the "where" clause for a specific subclass
by Peter Fassev (JIRA)
Error during a entity collection loading - wrong SQL query generation - missing discriminator condition in the "where" clause for a specific subclass
-----------------------------------------------------------------------------------------------------------------------------------------------------
Key: HHH-2855
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2855
Project: Hibernate3
Issue Type: Bug
Components: core
Affects Versions: 3.2.5
Reporter: Peter Fassev
Priority: Critical
Attachments: testcase.zip
There is a problem, when loading a entity collection (bag), when the collection element is a subclass. The query, witch fetches the elements of the collection, does not use the discriminator value of a subclass and thus loads also other elements form different classes. Please look at the simple test case I have provided.
Here is a simple description:
Having a base class A with two subclasses AA and AB, the class A has many-to-one connection to another base class B. The class B itself has two different collections (bags), the first contains only AA elements, the second bag BB elements. The classes AA and AB has different integer properties.
When I try to load an instance of class B, which is connected to some AA and AB instances, and than try to access the list of all connected AA instances, there is an exception, because Hibernate tries to load all AA and AB instances in one and the same AA collection. The exception is actually thrown, because Hibernate tries to instanciate an AA instance from a AB data! This is the case, because the selection query, which is generated automatically by Hibernate, does not use the discriminator value of the AA subclass to load the collection, and thus selects the AA and AB elements from the database.
WORKAROND: Currently, the only workaround i found is to define a "where" parameter in the hibernate-mapping with for each collection with the appropriated subclass discriminator.

[Hibernate-JIRA] Created: (HHH-2650) Allow for an entire Session to be readOnly, add Session.setReadOnly() method
by Gunther Schadow (JIRA)
Allow for an entire Session to be readOnly, add Session.setReadOnly() method
----------------------------------------------------------------------------
Key: HHH-2650
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2650
Project: Hibernate3
Issue Type: Sub-task
Components: core
Environment: Any
Reporter: Gunther Schadow
There is a need for read-only applications to avoid any snapshoting of objects if that application never intends to make updates. Such readOnly mode would be the mode in which any object gets loaded into the session, whether directly or from lazy collections. The use case is reporting applications which want to make sure that they don't even accidentally make updates AND that want to save the time it takes to create snapshots because they read through a lot of data very quickly. Our own need is that we have a rich client where we hold read only sessions open for browsing and where we spawn off any change transactions into separate Sessions. Even in change transactions we like to have all objects locked from even accidental updates unless they are explicitly unlocked.
A Session.setReadOnly() method would be ideal to do this. It does not appear very hard to make that improvement. We would do it ourselves even if we had some idea if (and under which criteria) our modifications would have a chance to make it into future versions of Hibernate?

[Hibernate-JIRA] Created: (ANN-632) @IndexColumn doesn't set value of index column
by Dan Allen (JIRA)
@IndexColumn doesn't set value of index column
----------------------------------------------
Key: ANN-632
URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-632
Project: Hibernate Annotations
Issue Type: Bug
Components: documentation
Affects Versions: 3.3.0.ga
Reporter: Dan Allen
I'm sure I will get screamed at for this, but the @IndexColumn just doesn't work with @OneToMany. When I say it doesn't work, it means that I am a reasonable person and I have studied the documentation for at least 4 hours and I just cannot figure out how to make it work. So either the documentation needs to be improved, or there is something wrong with Hibernate. I refuse to believe that I am this stupid.
Here is my problem in a nutshell. I have a Person and a collection of Jobs. The Jobs should be an indexed list based on the history that the person holds them.
@Entity
public class Person {
@Id @GeneratedValue
private long id;
@Column
private String name;
@OneToMany(cascade=ALL, fetch=LAZY, mappedBy = "job")
@IndexColumn(base = 1, name = "order")
private List<Job> jobs = new ArrayList<Job>();
// getters and setters
}
@Entity
public class Job {
@Id @GeneratedValue
private long id;
@Column
private String name;
@ManyToOne
@JoinColumn(name="person_id")
private Person person;
@Column
private Integer order;
// getters and setters
}
If I do the following, I get NULL for order.
Person person = new Person();
person.setName("Chuck")
Job job1 = new Job();
job1.setName("sysadmin")
job1.setPerson(person);
person.getJobs().add(job1);
Job job2 = new Job();
jobs2.setName("network admin")
job2.setPerson(person);
person.getJobs().add(job2);
entityManager.persist(person);
Assume that the reason I am not assigning an order is more complex than this example. The point is that we want to see the order column populated with the index of the list.
Now, if you give me the business about removing mappedBy, to that I will respond that by removing mappedBy, Hibernate tries to work with a person_job table, which I don't want. I want two tables, one for person and one for job.

I have an entity, named Group:

But, 'GROUP' is the reserved word of MySQL query language.
Log of hibernate show, that queries is without quotes:

Only one @IndexedEmbedded collection working in my entity.
----------------------------------------------------------
Key: HSEARCH-233
URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-233
Project: Hibernate Search
Issue Type: Bug
Affects Versions: 3.0.1.GA
Environment: JBoss AS 4.2.2 Windows
Reporter: sam doyle
Attachments: jiraFiles.tar.gz
This is supposedly pretty basic functionality so perhaps it is my particular case that it is causing it.
In the attachment files the EmtVenue class is the root of the indexing.
It contains two @IndexedEmbedded
@OneToMany( cascade = CascadeType.ALL, fetch = FetchType.LAZY, mappedBy = "emtVenue" )
@IndexedEmbedded
public Set<ClientGroupVenue> getClientGroupVenues()
@Embedded
@ManyToOne( fetch = FetchType.LAZY )
@JoinColumns( { @JoinColumn( nullable = false, name = "HOST", referencedColumnName = "HOST" ),
@JoinColumn( nullable = false, name = "zone", referencedColumnName = "ZONE" ) } )
@NotNull
@IndexedEmbedded
public Zones getZones()
In this case when I index EmtVenue the resulting index contains only values that correspond to Zones and no ClientGroupVenues.
When I comment out the @IndexedEmbedded on the Zones the resulting index does show the categories.
One side note that might be of interest is indexing of Zones results in referencing some entities which don't exist that I'm catching due to the data not being in sync.

[Hibernate-JIRA] Created: (HHH-2354) Schema validation too rigid for MySql enums

Schema validation too rigid for MySql enums
-------------------------------------------
Key: HHH-2354
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2354
Project: Hibernate3
Type: Bug
Components: metamodel
Environment: jboss-seam-1.1.0.GA, MySQL 5
Reporter: Zeljko Trogrlic
Enum column type in MySQL is handled as CHAR in their JDBC driver and should be mapped to String Java type.
However, Hibernate expects varchar(n) and fails to do the validation.
This is how DatabaseMetaData.getColumns describes it:
DATA_TYPE=1
TYPE_NAME=enum
Note that although TYPE_NAME is enum, DATA_TYPE represents CHAR.
Hibernate reports following exception:
13:49:31,397 INFO [TableMetadata] table found: configuration.userdb_domain_acl
13:49:31,397 INFO [TableMetadata] columns: [id, enabled, tablename, domain]

Validation should be fixed/relaxed to avoid this problem.

[Hibernate-JIRA] Created: (EJB-277) allow string values for query hints
by Norman Richards (JIRA)
allow string values for query hints
-----------------------------------
Key: EJB-277
URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-277
Project: Hibernate Entity Manager
Type: Improvement
Reporter: Norman Richards
It seems that some string values are not accepted as query hint values in hibernate. In specific, I was trying to convert a simple query that uses setHint("org.hibernate.cacheable", true) to use an XML-defined EntityQuery that uses
<framework:entity-query name="allCategories"
ejbql="select c from Category c"
order="c.name">
<framework:hints>
<key>org.hibernate.cacheable</key>
<value>true</value>
</framework:hints>
</framework:entity-query>
Unfortunately, this fails with an IllegalArgumentException:
Caused by: java.lang.IllegalArgumentException: Value for hint
at org.hibernate.ejb.QueryImpl.setHint(QueryImpl.java:160)
at org.jboss.seam.framework.EntityQuery.createQuery(EntityQuery.java:114)
at org.jboss.seam.framework.EntityQuery.getResultList(EntityQuery.java:41)

at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)
at java.lang.reflect.Method.invoke(Method.java:585)
...
Although I didn't try it, I would assume this would also fail from a @QueryHint in on a named query since that annotation only accepts a string
value.
I don't think this is technically a bug, but it would be very convenient if all the hints could accept string values.
