Hello

I have a design where I would like to have cascading saves. The only trouble is that the father is not aware of its childs, but the childs knows of its father.

Example:

A folder, has one father folder and many child folders. Problem is that the child knows of the father not the other way around.

I am wondering if I can implement cascade anyway, so when I save the father. The child is saved as well?

Just posted my mapping file


<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 2.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd" >

<hibernate-mapping package="data">

<class name="Folder" table="folder">
<id name="folderID" column="Folder_ID" type="java.lang.Integer" unsaved-value="0" >
<generator class="native"/>
</id>

<property name="folderName" column="Folder_Name" type="java.lang.String" not-null="true" />
<property name="folderCreatedDate" column="Folder_Created_Date" type="java.lang.Long" not-null="true" />

<one-to-one name="project" class="Project" />

<list name="childfolders" table="folder" cascade="all">
<key column="FK_Father_Folder_ID"/>
<index column="list_idx" />
<one-to-many class="data.Folder"/>
</list>


</class>

</hibernate-mapping>

Maybe thorugh interceptor, but certainly not in a efficient way.
