Hello guys I need your help. My problem is here :
public News merge(News detachedInstance) {
log.debug("merging News instance");
try {
News result = entityManager.merge(detachedInstance);
log.debug("merge successful");
return result;
} catch (RuntimeException re) {
log.error("merge failed", re);
throw re;
}
}
Error is : Caused by Java.lang
at News.merge(253) etc
