[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-1513) Duplicated entities in a one-to-many select

Duplicated entities in a one-to-many select ------------------------------------------- Key: HHH-1513 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1513 Project: Hibernate Core Issue Type: Bug Components: query-criteria Affects Versions: 3.0.5, 3.1.2 Environment: Oracle Reporter: Tiago Rinck Caveden Priority: Minor Attachments: mappings.zip Using a criteria to obtain a full select on an class that has a one-to-many eager property returns duplicated entities. It seems it's making the returned list to have the same size of the result set returned by the join necessary to fetch the rows. Here's the code I'm executing: Session sessao = getSession(); try { Criteria criterio = sessao.createCriteria(TipoErro.class); return criterio.list(); } finally { releaseSession(sessao); } And here's the mapping of the one-to-many property: <set name="emailsNotificacao" inverse="true" lazy="false" fetch="join"> <key column="ID_TIPO_ERRO" not-null="true" /> <one-to-many class="com.matera.inss.entity.EmailNotificacao" /> </set> I'll attach both the mapping of the parent entity, and of the child entity (don't know if it might help). Changing the use of the criteria by a find("from TipoErro") works perfectly. There's already a topic opened on the forum about this same issue, with more details and examples. Here's the topic: http://forum.hibernate.org/viewtopic.php?t=955186 Thank you very much, Tiago.
