I got this exception :
org.hibernate.QueryException: could not resolve property: type_eko of: data.Releve

In java I got 2 classes : Releve.java and ReleveId.java ('ReleveID' represents the composite-id of 'Releve')

How should I do to access "Releve.ReleveId.type_eko" from my HQL query ??



Hibernate version:
Hibernate3

Mapping documents:

<class name="data.Releve" table="releve">
<composite-id name="id" class="data.ReleveId">
<key-property name="timestamp" type="timestamp">
<column name="timestamp" length="19" />
</key-property>
<key-property name="ekoId" type="integer">
<column name="eko_id" />
</key-property>
<key-property name="idCompteur" type="integer">
<column name="id_compteur" />
</key-property>
<key-property name="typeEko" type="integer">
<column name="type_eko" />
</key-property>
</composite-id>
<property name="aler
...

HQL Query:

releveList = (List) session.createCriteria(Releve.class)
.add( Expression.in( "type_eko" , new Integer[] { 0,1 }) )

How about

Code:
releveList = (List) session.createCriteria(Releve.class)
            .add( Expression.in( "id.type_eko" , new Integer[] { 0,1 }) )
