[Hibernate-JIRA] Created: (ANN-598) Add ON clause to @ForeignKey

Add ON clause to @ForeignKey
----------------------------
Key: ANN-598
URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-598
Project: Hibernate Annotations
Issue Type: New Feature
Components: binder
Reporter: Christian Bauer
More important than it sounds:
@org.hibernate.annotations.ForeignKey(name = "FK_FEED_DIRECTORY_ID")
I need ON CASCADE DELETE on many of my foreign keys, so I have to do this right now via:
<hibernate-mapping>
<database-object>
<create>
alter table FEED drop constraint FK_FEED_DIRECTORY_ID;
alter table FEED add constraint FK_FEED_DIRECTORY_ID foreign key (DIRECTORY_ID) references NODE on delete cascade;
</create>
<drop></drop>
</database-object>
</hibernate-mapping>
This is a bit annoying, especially since @JoinColumn(columnDefinition) is also not an option - I don't want to hardcode my HSQL datatypes.
So we should accept a parameter on @ForeignKey (I know that the Hibernate binder doesn't have that notion at all, we need it in native Hibernate as well) that accepts "[ON {DELETE | UPDATE} {CASCADE | SET DEFAULT | SET NULL}];" and does the right thing during schema export.

[Hibernate-JIRA] Created: (HHH-2882) QueryKey.equals() returning false with distributed caching
by Daniel Campagnoli (JIRA)
QueryKey.equals() returning false with distributed caching
----------------------------------------------------------
Key: HHH-2882
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2882
Project: Hibernate3
Issue Type: Bug
Components: query-criteria
Affects Versions: 3.2.5
Reporter: Daniel Campagnoli
We noticed some issues recently with the query cache when using Coherence as the cache provider. This was due to instances of org.hibernate.cache.QueryKey not being equal after being serialized then deserialized.
The equals check was failing on the [ResultTransformer customTransformer] field which in our case had an instance of RootEntityResultTransformer (which comes from the field CriteriaSpecification.ROOT_ENTITY). This is because RootEntityResultTransformer doesnt override equals, so the check is done by reference equality. When the QueryKey has been serialized and deserialized out of the cache, the instance will always be different, so the equals check will fail.
A fix for this to be implement equals for RootEntityResultTransformer (and possibly the other ResultTransformer's). I used the following which worked fine.
public boolean equals(Object obj) {
return obj != null && this.getClass() == obj.getClass();
}
ps. I created HHH-1665 a while ago, a real simple fix, could that be looked at :)

[Hibernate-JIRA] Created: (ANN-554) NPE with @Id on @OneToOne
by Loïc Minier (JIRA)
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
at org.hibernate.util.StringHelper.qualify(StringHelper.java:264)

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,

jdbc reengineer sql-type problem with oracle 9i
-----------------------------------------------
Key: HBX-779
URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-779
Project: Hibernate Tools
Type: Bug
Components: reverse-engineer
Versions: 3.2beta8
Environment: windowsxp sp2, jdk 1.4.2, eclipse 3.1.2
Reporter: jacky hua
I used the ant task hibernate-tools provided like the below to generate hbms xml
<target name="default" description="generate hbm">
<delete dir="./generate"/>
<mkdir dir="./generate"/>
<hibernatetool destdir="./generate">
<jdbcconfiguration
configurationfile="./metadata/hibernate.cfg.xml"
revengfile="./metadata/hibernate.reveng.xml"
packagename="net.ema.examples.sa"
detectmanytomany="true"
detectoptimisticlock="true">
</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
SYSTEM "http://hibernate.sourceforge.net/hibernate-reverse-engineering-3.0.dtd" >
<hibernate-reverse-engineering>
<schema-selection match-catalog="TITAN" match-schema="TITAN" />
<type-mapping>
<!-- jdbc-type is name fom java.sql.Types -->
<!-- length, scale and precision can be used to specify the mapping precisly -->
<sql-type jdbc-type="NUMERIC" precision="1"
hibernate-type="boolean" />
<!-- the type-mappings are ordered. This mapping will be consulted last,
thus overriden by the previous one if precision=1 for the column -->
<sql-type jdbc-type="NUMERIC" precision="19" hibernate-type="long" />
<sql-type jdbc-type="TIMESTAMP" hibernate-type="java.util.Date" />
</type-mapping>
<!-- BIN$ is recycle bin tables in Oracle -->
<table-filter match-name="BIN$.*" exclude="true" />
</hibernate-reverse-engineering>
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:
<class name="net.ema.examples.sa.UserModel" table="T_SA_USER" schema="TITAN">
<id name="userId" type="big_decimal">
<column name="USER_ID" scale="0" />
<generator class="assigned" />
</id>
<property name="logonName" type="string">
<column name="LOGON_NAME" length="60" />
</property>
<property name="password" type="string">
<column name="PASSWORD" length="80" />
</property>
<property name="isOrgAdmin" type="java.lang.Boolean">
<column name="IS_ORG_ADMIN" precision="1" scale="0" />
</property>
<property name="remark" type="string">
<column name="REMARK" length="400" />
</property>
<property name="createDate" type="java.util.Date">
<column name="CREATE_DATE" length="11" />
</property>
<property name="status" type="string">

[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.
