NPE with @Id on @OneToOne
-------------------------
Key: ANN-554
URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-554
Project: Hibernate Annotations
Type: Bug
Versions: 3.2.1
Environment: Hibernate 3.2.2 GA, Hibernate Annotations 3.2.1, J2SE 1.6.0-b105 on Debian GNU/Linux sid, PostgreSQL 7.4
Reporter: Loïc Minier
Priority: Minor
Hi,
(Note: I originally reported this on the forum, but the lack of response suggests this might be a bug in Hibernate Annotations or Hibernate; the forum topic is at: http://forum.hibernate.org/viewtopic.php?t=970823)
I hope it's not a misuse of Hibernate, but I'm trying to use @Id on @OneToOne, and this causes the following NPE when running hbm2ddl:
java.lang.NullPointerException

What I'm trying to do at the application level is:
Foo class and table
long foo_id, primary key
FooData fooData, nulllable=true
FooData class and table
foo_id references Foo(foo_id), nullable=false
This is expressed in Java as:
@Entity
@Table(name = "foo")
public class Foo {
@Id @GeneratedValue
@Column(name = "foo_id")
Long id;
@OneToOne(mappedBy = "foo", cascade = CascadeType.ALL)
FooData fooData;
...
@Entity
@Table(name = "foo_data")
public class FooData {
@Id
@OneToOne
@JoinColumn(name = "foo_id", nullable = false)
Foo foo;
This causes a NPE here.
If I use a real Id on FooData, e.g.:
@Id
@Column(name = "foo_data_id")
Long id;
it works, and I end up with:
- foo_id in table foo as a primary key
- foo_data_id in table foo_data as a primary key
- foo_id in table foo_data not null
- foo_id in table foo_data references foo_id in table foo
I don't want a foo_data_id, I don't need it, hence the lack of it which leads to the NPE.
Bye,

[Hibernate-JIRA] Created: (HHH-3229) Make cascade rules more transparent/explicit/deterministic
by Chris Bredesen (JIRA)
Make cascade rules more transparent/explicit/deterministic
----------------------------------------------------------
Key: HHH-3229
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3229
Project: Hibernate3
Issue Type: Improvement
Components: core
Affects Versions: 3.2.6, 3.2.5, 3.2.4.sp1
Reporter: Chris Bredesen
Cascade rules are prone to different behavior based on the order in which properties appear in mapping XML. It is possible that an unexpected TransientObjectException may arise from certain operations when an object graph with circular references is merged (and possibly persisted/updated, etc).
For example, if a transient instance is reachable through more than once path from a root entity, it is not clear whether operations will be cascaded to it. The order in which the properties are mapped plays a part in determining cascade paths, but the rules are not documented.
Possible resolutions include:
1. Documenting the rules so that a programmer can make educated decisions about mapping.
2. Enhancing the algorithm such that order no longer matters and the rules are deterministic.
3. ???

I used the ant task hibernate-tools provided like the below to generate hbms xml
<target name="default" description="generate hbm">

<mkdir dir="./generate"/>
<hibernatetool destdir="./generate">
<jdbcconfiguration

<hbm2hbmxml destdir="./generate" />
</hibernatetool>
</target>
the ./metadata/hibernate.cfg.xml like the below:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-reverse-engineering

<!-- length, scale and precision can be used to specify the mapping precisly -->
<sql-type jdbc-type="NUMERIC" precision="1"

<!-- the type-mappings are ordered. This mapping will be consulted last,

But the <sql-type jdbc-type="NUMERIC" precision="19" hibernate-type="long" /> didn't work, also generate big_decimal type not long type, otherwise the others two sql-type rules worked. the not affected column:USER_ID was pk of my table. the generated hbm file is like the below:

[Hibernate-JIRA] Created: (HHH-2782) Component getType caches the type value
by Kiss Zoltán (JIRA)
Component getType caches the type value
---------------------------------------
Key: HHH-2782
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2782
Project: Hibernate3
Issue Type: Bug
Affects Versions: 3.2.5
Environment: all
Reporter: Kiss Zoltán
Component class caches the value of the type attribute:
public Type getType() throws MappingException {
// added this caching as I noticed that getType() is being called multiple times...
if ( type == null ) {
type = buildType();
}
return type;
}
This forbids the use of 'dynamic attributes'.
For eg. if you try to add new properties to an existing dynamic-component with the addProperty method, then the rebuild of the session factory will failed, because the Component property will be invalid during the validation (in the Component there will be a different column span value, then in the cached ComponentType).
There should be a method like this in the Component class:
public void rebuildType() {
type = buildType();
}
With the help of this the type could be rebuild if it is necessary.

Hi,
I am trying to load a many-to-many mapped collection using a sql query like this:
<sql-query name="loadItems">
<load-collection alias="item" role="test.Test.items"/>
select {item.*} from Items item where item.id = :id

This always fails due to a NullPointerException:

I provided a very simple TestCase + Mappings to illustrate the problem. The exception does not occur for one-to-many mappings.
Just for your information, we need this functionality in order to deal with DB2 problems we have.
I ran this TestCase against 3.2.5 and 3.2.6 and both failed.
Thanks.
