Maybe related to: https://svn.strategoxt.org/websvn/WebDSL?op=comp&compare[]=/webdsls/trunk/src/org/webdsl/dsl/to-java-servlet/java-entity-main.str@5667&compare[]=/webdsls/trunk/src/org/webdsl/dsl/to-java-servlet/java-entity-main.str@5668

part of the fix for allowing moving of composite items is a workaround to avoid triggering cascade orphan deletion in hibernate (found here https://forum.hibernate.org/viewtopic.php?f=1&t=1012422)

in generated Item.java, method setContainer(webdsl.generated.domain.Container newitem):

        utils.HibernateUtil.getCurrentSession().flush();
        UUID oldid = oldthing.getId();
        utils.HibernateUtil.getCurrentSession().evict(oldthing);
        oldthing = (webdsl.generated.domain.Container) utils.HibernateUtil.getCurrentSession().load(webdsl.generated.domain.Container.class, oldid);
        oldthing.removeFromItems(this);

Disabling the test for now. We need better support for deletions in general before going into specific cases like this. This will require a solution outside of Hibernate to provide better detection and error reporting of referential integrity contraint violations, or custom delete cascading rules.
