Hi Martin,
I'm not sure if this is an intended effect, but if I set the option
PersistenceOptions.MAP_ALL_LISTS_AS_IDBAG =true I get an incomplete mapping
of referrers for objects with many-to-many relations.
A comparison in the mapping file shows the difference:
1) PersistenceOptions.MAP_ALL_LISTS_AS_IDBAG =false
....
<list name="predefinedAttributeValues"
table="`datapointattributeholder_predefinedattributevalues` " lazy="true">
<key update="true">
<column name="`datapointattributeholder_e_id`"
not-null="true" unique="false"
index="DatapointAttributeHolder_predefinedAttributeValues"/ >
</key>
<list-index
column="`datapointattributeholder_predefinedattributevalues_idx` "/>
<many-to-many entity-name="AttributeValueDefinition"
unique="false"
foreign-key="datapointattributeholder_predefinedattributevalues ">
<column name="`attributevaluedefinition_id`"
not-null="true" unique="false"
index="DatapointAttributeHolder_predefinedAttributeValues"/ >
</many-to-many>
</list>
....
2) PersistenceOptions.MAP_ALL_LISTS_AS_IDBAG =true
....
<idbag name="predefinedAttributeValues"
table="`datapointattributeholder_predefinedattributevalues` " lazy="true">
<collection-id column="ID" type="long">
<generator class="increment"/>
</collection-id>
<key update="true">
<column name="`datapointattributeholder_e_id`"
not-null="true" unique="false"
index="DatapointAttributeHolder_predefinedAttributeValues"/ >
</key>
<many-to-many entity-name="AttributeValueDefinition"
unique="false"
foreign-key="datapointattributeholder_predefinedattributevalues ">
<column name="`attributevaluedefinition_id`"
not-null="true" unique="false"
index="DatapointAttributeHolder_predefinedAttributeValues"/ >
</many-to-many>
</idbag>
...
In the HbDataStore.computeReferers() method prop.getValue() returns a List
in 1) above and an IdentifierBag in 2). For the case of an IdentifierBag the
clause
"else if (prop.getValue() instanceof List || prop.getValue() instanceof
Bag)" is returning false as the IdentifierBag isn't an instance of either a
List nor a Bag.
The IdentifierBag is extending the IdentifierCollection which extends the
org.hibernate.mapping.Collection, the Bag is also extending the
org.hibernate.mapping.Collection but isn't extended by the IdentifierBag.
Is this a bug or a feature? ;-)
Greetings
Bj

Can you already say if you rather check instanceof for
org.hibernate.mapping.Collection instead of org.hibernate.mapping.Bag, or
add a check for org.hibernate.mapping.IdentifierBag? Just that I can fix it
locally until the update comes. :-)

Hi Björn,
Thanks for the bugzilla.
It will probably be org.hibernate.mapping.Collection.
