[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-4887?page=c... ] Emmanuel Bernard commented on HHH-4887: --------------------------------------- In case of @MapsId, we force PERSIST to @XToOne to ensure that em.persist(derivedEntity); em.persist(associatedEntity); This was not the case when @IdClass was used. I've now fixed the problem but the issue still remains. Actually even when manually setting @ManyToOne(cascade=CascadeType.PERSIST), the issue remains. Could there be an issue where the mapper class is hosting the @XToOne ? -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
