[hibernate-dev] cascading deletion issue

[Teresa Batista Neto]

Dear all,

I'm trying to use cascading deletion but it doesn't seem to work.

"
If you can guarantee that no other object (or row in any other table) holds
a reference to these bids, you can make the deletion transitive.
Hibernate (and JPA) offer a cascading option for this purpose. You can
enable cascading for the delete operation
<set name="bids" inverse="true" cascade="save-update, delete">
"

Only works for me if I'm mapping to a Set... If I use List it stops working
and returns java.util.ConcurrentModificationException...

Any ideas?


<class name="SimpleDatabase" table="TERM">
       .....
       <list name="optionalFields"
           table="OPTIONAL_FIELD"
           lazy="false"
           fetch="subselect"
           inverse="true"
           cascade="save-update, delete, delete-orphan"
      >
            <key column="TERM_ID"/>
            <list-index column="FIELD_ORDER" base="1"/>
            <one-to-many class="SimpleDatabaseOptionalField"/>
      </list>
</class>

<class name="SimpleDatabaseOptionalField" table="OPTIONAL_FIELD">
        <id name="fieldId" column="FIELD_ID" type="integer">
            <generator class="sequence">
                <param name="sequence">SEQ_XREFDB</param>
            </generator>
        </id>
        <property name="termId" column="TERM_ID" type="integer"/>
        <property name="fieldOrder" column="FIELD_ORDER" type="integer"
not-null="true" />
        <property name="description" column="DESCRIPTION" type="string"
not-null="true"/>
        <property name="xmlPropertyName" column="XML_PROPERTY_NAME"
type="string" not-null="true"/>
        <property name="rdfPropertyName" column="RDF_PROPERTY_NAME"
type="string" not-null="true"/>
    </class>



Thanks in advance,
Teresa
