Hi,
with latest stable OpenJPA i have a problem which might be there because of
misunderstanding on my side.
For instance take these PC class:
Class A {
public int oid;
public String name;
public B classB;
}
Class B {
public int oid;
public String name;
}
Now my appCode:
--------------------------
A classA = new A();
a.setName("foo");
B classB = someDao.findClassB();
classA.setB(classB); // classB is detached for this example
em.persist(classA);
=====
When i do this, i am getting the exception that i cant persist a detached class
(classB). This is okay and i am aware of that. Now i tried to attach "B" to the
context before persisting via:
em.merge(classB);
Really interessting is that after the merge, the call to
OpenJPAEntityManager.isDetached() still returns TRUE. Consequently i still cant
persist "A".
So my overall problem is that i cant persist a new Entity when this new entity
has a detached object inside the graph because i cant bring the detached object
back into the current context.
Thanks for hints.
