Hi,
I use a table per subclass startegy for mapping the following
inheritance structure;
AbstractPropertyDefinition - ListPropertyDefinition
- RangePropertyDefinition
I noticed when issue the following statement:
session.CreateCriteria<AbstractPropertyDefinition>
().List<AbstractPropertyDefinition>();
nHibernate issues an update before actually selecting. I wonder why he
is updating the joined-subclass properties before fetching them?
Regards
Yoeri
<class name="AbstractPropertyDefinition" abstract="true"
table="propertydefinitions" lazy="false">
<id name="ID" column="PropertyDefinition_ID" type="int">
<generator class="native"></generator>
</id>
<many-to-one name="Label" class="Translation"
column="LabelTranslation_ID" cascade="all" />
<property name="Target" column="Target" type="int"></property>
<joined-subclass table="listpropertydefinitions"
name="ListPropertyDefinition" lazy="false">
<key column="PropertyDefinition_ID"/>
<property name="Type" column="Type"
type="int"></property>
<bag name="Items" inverse="true" lazy="true"
cascade="save-update">
<key column="ListPropertyDefinition_ID"/>
<one-to-many

</bag>
</joined-subclass>
<joined-subclass table="rangepropertydefinitions"
name="RangePropertyDefinition" lazy="false">
<key column="PropertyDefinition_ID"/>
<property name="Type" column="Type"
