I need a parent child relationship (with inverse="true"..) implemented with a list; reading documentation and posts in the forum I know that:
1) list is not the canonical form of collection to map parent/child
2) someone has proposed a workaround: http://www.hibernate.org/193.html , but It seems that there are still some problems.
Starting from this, a (very) little modification:


PARENT CLASS:

public class Parent {

Long id;
Integer version;
String desc;
List childs = new ArrayList();

public void addChild(Child child) {
child.setParent(this);
childs.add(child);
}


public void delChild(int index) {
childs.remove(index);
}


// accessors and mutators omitted

}



CHILD CLASS:

public class Child {

Long id;
Integer version;
String description;
Parent parent;


public Integer getIndex() {
if (parent!=null) // for childs created but not yet added to parent...
return new Integer(this.getParent().getChilds().indexOf(this));
else
return null;
}


public void setIndex(Integer index) {
// do nothing
}


// other accessors and mutators omitted


}



PARENT MAPPING:

<class name="Parent">
<id name="id" column="id" type="long">
<generator class="native"/>
</id>
<version name="version"/>
<property name="description" type="string"/>
<list name="childs" inverse="true" lazy="true" cascade="all-delete-orphan">
<key column="parent"/>
<index column="index"/>
<one-to-many class="Child"/>
</list>
</class>



CHILD MAPPING:

<class name="Child">
<id name="id" column="id" type="long">
<generator class="native"/>
</id>
<version name="version"/>
<property name="description" type="string"/>
<property name="index" type="integer"/>
<many-to-one
name="parent"
column="parent"
class="Parent"
not-null="true"/>
</class>



It seems to work well, but any feedback will be appreciated.


Thanks

Note that this problem is completely fixed in HB3. Wait for the next release.

Thanks, but... the classes and mappings I've posted are working or not?
I'm still confused...what's exactly the problem?
