Incomplete insert and update using <<insert="false" update="false">> -------------------------------------------------------------------- Key: HHH-1909 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1909 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.0 final Reporter: Peppe Assignee: Gail Badner Priority: Critical Hi, I've seen lots of people have problems using complex mappings. This is my situation, I've three mappings: <hibernate-mapping> <class name="unibiblio.dati.anagrafica.DAO.Persone" table="persone"> <composite-id name="id" class="unibiblio.dati.anagrafica.DAO.PersoneId"> <key-property name="idUtente" type="java.lang.Integer"> <column name="id_utente" /> </key-property> <key-property name="codbib" type="java.lang.Integer"> <column name="codbib" /> </key-property> </composite-id> <many-to-one name="dizTitolidistudio" class="unibiblio.dati.anagrafica.DAO.DizTitolidistudio" update="false" insert="false" fetch="select"> <column name="lingua" length="2" /> <column name="codice_titolostudio" length="1" /> </many-to-one> <many-to-one name="dizLingue" class="unibiblio.dati.anagrafica.DAO.DizLingue" fetch="select"> <column name="lingua" length="2" /> </many-to-one> <many-to-one name="dizProfessioni" class="unibiblio.dati.anagrafica.DAO.DizProfessioni" update="false" insert="false" fetch="select"> <column name="lingua" length="2" /> <column name="codprofessione" length="2" not-null="true" /> </many-to-one> <property name="userName" type="string"> <column name="user_name" length="30" /> </property> <property name="password" type="string"> <column name="password" length="30" /> </property> . . . . . . </class> </hibernate-mapping> <hibernate-mapping> <class name="unibiblio.dati.anagrafica.DAO.DizTitolidistudio" table="diz_titolidistudio"> <composite-id name="id" class="unibiblio.dati.anagrafica.DAO.DizTitolidistudioId"> <key-property name="lingua" type="string"> <column name="lingua" length="2" /> </key-property> <key-property name="codiceTitolostudio" type="string"> <column name="codice_titolostudio" length="1" /> </key-property> </composite-id> <many-to-one name="dizLingue" class="unibiblio.dati.anagrafica.DAO.DizLingue" update="false" insert="false" fetch="select"> <column name="lingua" length="2" not-null="true" /> </many-to-one> <property name="titolo" type="string"> <column name="titolo" length="50" not-null="true" /> </property> <set name="persones" inverse="true"> <key> <column name="lingua" length="2" /> <column name="codice_titolostudio" length="1" /> </key> <one-to-many class="unibiblio.dati.anagrafica.DAO.Persone" /> </set> </class> </hibernate-mapping> <hibernate-mapping> <class name="unibiblio.dati.anagrafica.DAO.DizProfessioni" table="diz_professioni"> <composite-id name="id" class="unibiblio.dati.anagrafica.DAO.DizProfessioniId"> <key-property name="lingua" type="string"> <column name="lingua" length="2" /> </key-property> <key-property name="codprofessione" type="string"> <column name="codprofessione" length="2" /> </key-property> </composite-id> <many-to-one name="dizLingue" class="unibiblio.dati.anagrafica.DAO.DizLingue" update="false" insert="false" fetch="select"> <column name="lingua" length="2" not-null="true" /> </many-to-one> <property name="professione" type="string"> <column name="professione" length="50" /> </property> <set name="persones" inverse="true"> <key> <column name="lingua" length="2" /> <column name="codprofessione" length="2" not-null="true" /> </key> <one-to-many class="unibiblio.dati.anagrafica.DAO.Persone" /> </set> </class> </hibernate-mapping> The problem is when I try to insert a new persone it make an incomplete SQL statement because <<update="false" insert="false">> in <many-to-one name="dizTitolidistudio"> and <many-to-one name="dizProfessioni"> causes hiding setting of columns "codice_titolostudio" and "codprofessione" in the generated SQL Deleting that tag, of course, give me the exception ERROR [STDERR] org.hibernate.MappingException: Repeated column in mapping for entity: unibiblio.dati.anagrafica.DAO.Persone column: lingua (should be mapped with insert="false" update="false") I workarounded this extracting "codice_titolostudio" and "codprofessione" as properties in Persone and setting them with classes but I don't like this. Am I wrong or is it a bug?
