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

GNU/Linux sid, PostgreSQL 7.4

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

at org.apache.tools.ant.launch.Launcher.run(Launcher.java:246)
at org.apache.tools.ant.launch.Launcher.main(Launcher.java:67)
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,

---------------------------------
I personally still experience the issue -- but only with the mappedBy OneToOne, not if I
remove it --, and was not able to locate the fix you committed by looking at
http://anonsvn.jboss.org/repos/hibernate/trunk/HibernateExt nor in
http://anonsvn.jboss.org/repos/hibernate/trunk/Hibernate3; could you point me to the fix?
Thanks!

Something probably related to this bug. I'm quite sure I have misconfigured something,
but I get the following error when using OneToOne mappings. Failing more gracefully would
be nice.

NPE with @Id on @OneToOne
-------------------------
Key: ANN-554
URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-554
Project: Hibernate Annotations
Type: Bug
Components: binder
Versions: 3.2.1
Environment: Hibernate 3.2.2 GA, Hibernate Annotations 3.2.1, J2SE 1.6.0-b105 on Debian

Fix For: 3.3.0.ga
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

at org.apache.tools.ant.launch.Launcher.run(Launcher.java:246)
at org.apache.tools.ant.launch.Launcher.main(Launcher.java:67)
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,

Serdyn du Toit commented on ANN-554:
------------------------------------
Had a similar error. I made a few changes to entities without one-to-one mappings.
During attempting to solve this I commented all the one-to-one mappings from OTHER
entities - this then gave a different error.
The error is discussed here:
https://svn.cargo.codehaus.org/browse/GRAILS-4215?focusedCommentId=169191...
My problem:
I had the jbossall-client.jar on the classpath which references similar classes in similar
packages.
Just mentioning this here in case someone with similar issues stumbles upon this page.
