Hi,
my problem: how to delete a relation when using "Non-Decomposed m:n Mapping".
After removing an object from a collection (RemovalAwareCollection) and
saving the object
(PersistenceBrokerFactory.defaultPersistenceBroker().store(Object o)) not only
the relation is deleted but also the ralated object, i.e. the one
that has been removed from the collection. Can this be avoided? F.e. i don't
want to delete a 'project' when removing a 'project' from 'user'. Only the entry
in the
indirection-table that mapps projects to users should be deleted.
Regards
Klaus
collection xml:
...
<collection-descriptor
name="projects"
collection-class=
"org.apache.ojb.broker.util.collections.RemovalAwareCollection"
element-class-ref="com.imd.paris.base.Projects"
indirection-table="user_projects"
auto-delete="false"
auto-update="true">
<fk-pointing-to-this-class column="user_id"/>
<fk-pointing-to-element-class column="project_id"/>
</collection-descriptor>
