[jira] Created: (OPENJPA-187) MEMBER OF query fails on OpenJPA, but
works fine with TopLink and Hibernate EM
MEMBER OF query fails on OpenJPA, but works fine with TopLink and Hibernate EM
------------------------------------------------------------------------------
Key: OPENJPA-187
URL: https://issues.apache.org/jira/browse/OPENJPA-187
Project: OpenJPA
Issue Type: Bug
Components: query
Affects Versions: 0.9.7
Reporter: Jacek Laskowski
What's wrong with the following query?
Query query = em.createQuery("SELECT DISTINCT o FROM Osoba o WHERE :projekt MEMBER OF o.projekty");
query.setParameter("projekt", new Projekt("Apache OpenEJB", RodzajProjektu.OTWARTY));
List<Osoba> osoby = query.getResultList();
assert osoby.size() == 1 : "Otrzymano " + osoby.size();
where Projekt is an entity where @Id is of type String (the first input parameter in the two-param constructor above).
TopLink 2.0 BUILD 40 and Hibernate EntityManager 3.3.0.GA work fine whereas OpenJPA 0.9.7-SNAPSHOT finishes with the java.lang.AssertionError error (it's the test itself actually, but since the query returns 0 elements the issue originates in OpenJPA).

[jira] Commented: (OPENJPA-187) MEMBER OF query fails on OpenJPA,
but works fine with TopLink and Hibernate EM

Abe White commented on OPENJPA-187:
-----------------------------------
Does it work if you actually look up the "Apache OpenEJB" Projekt instance through the EntityManager rather than constructing a new one? It might be that OpenJPA is recognizing that the given Projekt isn't actually persistent.
