Hello!
I have the following model with parent/child relationship:
public interface ColocationGroup extends EObject {
/**
@model id="true" annotation="teneo.jpa appinfo='@Id
@GeneratedValue(strategy=SEQUENCE, generator=\"ColoGroupGen\")'"
*/
Long getId();
/**
@model opposite="parent" containment="true" annotation="teneo.jpa
appinfo='@OneToMany(fetch=EAGER)\r\n@Cascade({PERSIST, DELETE, REMOVE,
LOCK, REPLICATE, EVICT, REFRESH, DELETE_ORPHAN})'"
*/
EList<Colocation> getColocation();
}
public interface Colocation extends EObject {
/**
@model id="true"
*/
Long getId();
/**
@model opposite="colocation" transient="false" annotation="teneo.jpa
appinfo='@ManyToOne(fetch=EAGER)'"
*/
ColocationGroup getParent();
}
The following test code:
@Test
public void testRefresh() {
ColocationGroup parent =
ColocationFactory.eINSTANCE.createColocationGroup();
Colocation colo = ColocationFactory.eINSTANCE.createColocation();
parent.getColocation().add(colo);
sessionFactory.getCurrentSession().save(parent);
sessionFactory.getCurrentSession().save(colo);
sessionFactory.getCurrentSession().flush();
sessionFactory.getCurrentSession().clear();
sessionFactory.getCurrentSession().refresh(parent);
}

at org.hibernate.impl.SessionImpl.refresh(SessionImpl.java:886)
at com.phorm.cms.model.dao.GroupDaoTest.testRefresh(GroupDaoTes t.java:97)
It seems that during cascading ColocationGroup.colocation association
'colo' entity is initialized with the new ColocationGroup object
different from 'parent' that cause removing 'colo' form
parent.getColocation() collection that eventually leads to
ConcurrentModificationException exception. Looks like a bug, is there
any way to fix it?
Thank you,
Alexey

Hi Alexey,
Hmm, I think I need to debug this, seems like a bi-directional association relation issue.
Can you open a bugzilla with a small test model which reproduces this (and the code below)?
