Hi, i'm having problem creating a 1-1 relation. 1-N works fine, but when I try to do 1-1 it complains about not finding a setter. So weird!

Im using NetBeans 5.0 with the hibernate plugin.
All code below is auto generated by the plugin.


Hibernate version:
3.1.3
Mapping documents:

Kossa.hbm.xml:


<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping
>
<class
name="javaapplication3.Kossa"
table="KOSSA"
>

<id
name="id"
column="id"
type="java.lang.String"
>
<generator class="uuid.hex">
<!--
To add non XDoclet generator parameters, create a file named
hibernate-generator-params-Kossa.xml
containing the additional parameters and place it in your merge dir.
-->
</generator>
</id>

<one-to-one
name="apa"
class="javaapplication3.Apa"
cascade="none"
outer-join="auto"
constrained="false"
/>

<!--
To add non XDoclet property mappings, create a file named
hibernate-properties-Kossa.xml
containing the additional properties and place it in your merge dir.
-->

</class>

</hibernate-mapping>

Code between sessionFactory.openSession() and session.close():

package javaapplication3;

import org.hibernate.Session;
import org.hibernate.Transaction;

/**
* @netbeans.hibernate.facade beanClass=javaapplication3.Kossa
*/
public class KossaFacade {
public void saveKossa(Kossa kossa) {
Session session = javaapplication3.NewHibernateUtil.currentSession();
Transaction tx = session.beginTransaction();
session.save(kossa);
tx.commit();
javaapplication3.NewHibernateUtil.closeSession();
}

public void generate(){
Kossa kossa = new Kossa();
saveKossa(kossa);
}
}

But the bloody setter is clearly there!



package javaapplication3 ;
/**
*
*
* @hibernate.class
* table="KOSSA"
*
*/
public class Kossa {

// <editor-fold defaultstate="collapsed" desc=" PrimaryKey: String id ">
private String id;
/**
* @hibernate.id
* generator-class="uuid.hex"
*/
public String getId () {
return id;
}
public void setId (String id) {
this.id = id;
}
//</editor-fold>


// <editor-fold defaultstate="collapsed" desc=" 1-1 Relation to javaapplication3.Apa apa ">
private javaapplication3.Apa apa ;
/**
* @hibernate.one-to-one class = "javaapplication3.Apa"
*/
public javaapplication3.Apa getApa() {
return apa;
}
public void setApa() {
this.apa = apa;
}
// </editor-fold>

}


I've searched for hours but it seems noone has had this problem before. Really strange. Please help.

*cough*
Thought about putting "javaapplication3.Apa apa" into the argument section of your setter?

it should read:
public void setApa(javaapplication3.Apa apa) {
this.apa = apa;
}

;)

Holy crap!

When generating a 1-N relation it gets the set-method all correct. So I guess this is a bug in the plug-in...

This must be the most stupid thing I've spend four hours dealing with in my whole life. =)

Thanks for the answer!
