Integration Test: object references an unsaved transient instance
Hi,
I'm trying to run several tests in my application, and I'm facing what I believe to be the same bug in several tests.
First of all, everything is working fine in the application, I just have some troubles with the test and the same code.
Basically, a object references an unsaved transient instance
exception is thrown where it shouldn't be for odd reasons.
Example:
Everytime I perform a login in my test, I always have this exception on the auto performed logout (which is actually performing some database changes as you'll see below).
Here's my test data:
insert into Language (id, name, code,) values (0, 'English','en') insert into Users(id, username, password,language_id) values (0,'admin' , 'admin', 0)
Nothing too fancy.
When I login, I create an Event, which has a @OneToOne link to a User.
userEvent = new Event(); userEvent.setUser(currentUser); entityManager.persist(userEvent);
It's working well here too.
Then, the auto-performed logout:
@Observer("org.jboss.seam.preDestroyContext.SESSION")
public void logout() {
if (userEvent != null) {
try {
userEvent.end();
entityManager.merge(userEvent);
} catch (Exception e) {
log.error(e,e.getMessage());
}
}It's right there, on the entityManager.merge, that I have this strange exception:

I actually have no idea why it's happening, since I have this same problem on different test in my application, some being on totally different models than this ones.
