Hallo all,
I have the problem that I cannot delete a detached object.
My source codes are (I'm using the spring framework):
public void delete(final int id) {
final JpaTemplate t = getJpaTemplate();
T obj = t.find(getObjectClass(), id);
if (obj != null) {
obj = t.merge(obj);
t.remove(obj);
}
}
Looks strange, but obj what I got as result is also detached object... What
I'm doing wrong?
stack trace:
org.apache.openjpa.persistence.ArgumentException: You cannot perform
operation delete on detached object
"[EMAIL PROTECTED]".
This operation only applies to managed objects.
