Hi,
I have two entities: "Parent" & "Child"
Child is mapped in Parent like this:
Code:
<many-to-one name="child" class="org.demo.Child"
update="false" insert="false" embed-xml="false" node="chd/@id" >
<column name="CHILD_ID" precision="10" scale="0" not-null="true" />
</many-to-one>
and Child has an Enum type mapped like this:
Code:
<property name="toyType">
<column name="TOY_TYPE" length="100" />
<type name="org.demo.type.LabelEnumType">
<param name="enum">org.demo.ToyType</param>
<param name="defaultLabel"></param>
</type>
</property>
mapped as a "String" in CHILD.TOY_TYPE column
Everything works fine but I cannot do this:
Code:
DetachedCriteria dc = DetachedCriteria.forClass(Parent.class);
dc.add(Restrictions.and(
Restrictions.eq("child.id", childId),
Restrictions.eq("child.toyType", ToyType.CAR)));
dc.setProjection(Projections.rowCount());
int count = DataAccessUtils.intResult(getHibernateTemplate().findByCriteria(dc));
because I got:
nested exception is org.hibernate.QueryException: could not resolve property: child.toyType of: org.demo.Parent
so it looks like it cannot solve:
parent->child->toyType
probably because ToyType has not an own "Entity", but it is embedded.
Is there any workaround for it? I need to continue using DetachedCriteria as it will be "decorated" in other places of the code.
So I'm wondering if I can solve that always using DetachedCriteria.
Thanks,
Rand
