Cannot specify on-delete="cascade" for a map or a set with just one element
---------------------------------------------------------------------------
Key: HHH-2710
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2710
Project: Hibernate3
Issue Type: Improvement
Components: core
Affects Versions: 3.2.4
Reporter: Gerald Klopp
Priority: Minor
I'd like to specify the on-delete="cascade" attribute for a map or for a set
with just one element.
When I try to do this, I get the following exception :
Initial SessionFactory creation failed.org.hibernate.MappingException: only inverse
one-to-many associations may use on-delete="cascade"
The on-delete="cascade" attribute can be specified for more complex
relationships like one-to-many. But it seems that the case of a simple map or set is not
covered.
- Mapping document example:
<hibernate-mapping>
<class name="Document" table="DOCUMENT">
<id name="id" column="DOCUMENT_ID">
<generator class="native" />
</id>
<map name="titles" table="DOCUMENT_TITLE"
lazy="false">
<key column="DOCUMENT_ID" on-delete="cascade" />
<index column="LANGUAGE" type="string" />
<element column="TITLE" type="text"
not-null="true" />
</map>
<set name="references" table="DOCUMENT_REFERENCE"
lazy="false">
<key column="DOCUMENT_ID" on-delete="cascade" />
<element type="string" column="REFERENCE" />
</set>
</class>
</hibernate-mapping>
- Exception stack trace :

With Hibernate 3.2.5, I think this can be corrected by replacing in
org.hibernate.mapping.Collection :
"
public void validate(Mapping mapping) throws MappingException {
if ( getKey().isCascadeDeleteEnabled() && ( !isInverse() || !isOneToMany() ) )
{
throw new MappingException(
"only inverse one-to-many associations may use on-delete=\"cascade\":
"
+ getRole() );
}

public void validate(Mapping mapping) throws MappingException {

{
throw new MappingException(
"only inverse one-to-many associations may use on-delete=\"cascade\":
"

}
}

The table is correctly created (with an "ON DELETE CASCADE") and I can now use a
bulk delete.

-------------------------------------
I ran into this issue as well.
Why would be such a widely needed feature constrained only to inverse relations? Inverse
relations have an other set of annoying limitations.
It is becoming impossible to navigate between Hibernate limitations to do a decent
mapping.
Would be nice to have it incorporated in the next Hibernate release.
Cannot specify on-delete="cascade" for a map or a set with

I'd like to specify the on-delete="cascade" attribute for a map or for a
set with just one element.
When I try to do this, I get the following exception :
Initial SessionFactory creation failed.org.hibernate.MappingException: only inverse
one-to-many associations may use on-delete="cascade"
The on-delete="cascade" attribute can be specified for more complex
relationships like one-to-many. But it seems that the case of a simple map or set is not
covered.
- Mapping document example:
<hibernate-mapping>
<class name="Document" table="DOCUMENT">
<id name="id" column="DOCUMENT_ID">
<generator class="native" />
</id>
<map name="titles" table="DOCUMENT_TITLE"
lazy="false">
<key column="DOCUMENT_ID" on-delete="cascade" />
<index column="LANGUAGE" type="string" />
<element column="TITLE" type="text"
not-null="true" />
</map>
<set name="references" table="DOCUMENT_REFERENCE"
lazy="false">
<key column="DOCUMENT_ID" on-delete="cascade" />
<element type="string" column="REFERENCE" />
</set>
</class>
</hibernate-mapping>

I've also come across this issue. Would be great to see this fixed or an alternative
solution provided.

-----------------------------
I let myself to suggest swap places of !isInverse() || !isOneToMany() in if statement so
that this will work also for unidirectional @OneToMany associations where there is no
inverse="true"(XML) / mappedBy(annotations) side.

Jonathan commented on HHH-2710:
-------------------------------
I'm not sure if there's a related issue for this, but Hibernate also does not
allow OnDelete to be specified at all for many-to-many mappings. This limitation seems
arbitrary since cascading deletes to a join table via a foreign key could be very
important, from both sides of a many-to-many relationship.
