[eclipselink-users] synchronization of new object question

[Leon Derks <leon.derks@xxxxxxxxxx>]

I get the error message below when I run the following:

getEntityManager().createNamedQuery("findImageInfoByExample").setParameter("visualElementId", 
visualElementId).getSingleResult();

My question is, why is the entitymanager synchronizing during this 
query? I would expect to synchronize only during entityManager.persist() 
or merge().

I don't want to persist the new , but want to check if the same is 
already stored in the db.

Is it possible to disable the synchronisation?

Error:
During synchronization a new object was found through a relationship 
that was not marked cascade PERSIST: ****.model.ImageInfo
