Objet : RE : bug in em.find()
Thanks for the fix! Looking more in depth into the class, I see other problems
in JPA 2.0 methods.
- In the following methods:
public void lock(Object entity, LockModeType lockMode, Map<String, Object>
properties) {
public void refresh(Object entity, LockModeType lockMode, Map<String,
Object> properties) {
public void refresh(Object entity, LockModeType lockMode) {
public void refresh(Object entity, Map<String, Object> properties) {
entityManager is used in place of entity.
- Transaction management is not always correct (or at least not consistent
with JPA1 methods)
e.g. refresh methods does not assume an active transaction.
- Less important, timing measurement is implemented JPA 1 methods but not JPA2.
I should be able to provide a patch for this by tomorrow.
Thibaut

Objet : bug in em.find()
Hello there,
I think there is an error in JtaEntityManager class,in 2 find methods:
public <T> T find(Class<T> entityClass, Object primaryKey, LockModeType
lockMode) {
public <T> T find(Class<T> entityClass, Object primaryKey, LockModeType
lockMode, Map<String, Object> properties) {
when calling the delegate, entityManager is used in place of the primaryKey.
giving this exception at runtime:
Caused by: java.lang.ClassCastException:
org.apache.openjpa.persistence.EntityManagerImpl cannot be cast to
java.lang.Number
at
org.apache.openjpa.util.ApplicationIds.fromPKValues(ApplicationIds.java:179)
at
org.apache.openjpa.kernel.BrokerImpl.newObjectId(BrokerImpl.java:1267)
(3.2.-x branch and trunk)
Regards,
Thibaut Robert
