I used several forums but no suitable response
http://stackoverflow.com/questions/21186366/org-hibernate-objectnotfoundexceptionno-row-with-the-given-identifier-exists
https://forum.hibernate.org/viewtopic.php?f=1&t=1030539&start=0
Is it so difficult question? Because if this usecase is allowed than in hibernate was introduced bug.

Please use the user forum (https://forum.hibernate.org/) for help.

I dont think that this is problem if you mean
Uvazek u = ppv.uvazeks.iterator().next();
u.ppv = null;
ppv.uvazeks.remove(u);
is right code for remove entity from collection??
With this fix test still fails.
Things changed after this change
Ppv ppv = (Ppv) getSession().get(Ppv.class, 1l);
getSession().clear();
ppv.uvazeks.remove(ppv.uvazeks.iterator().next());
//to ppv I saved merged entity
ppv = (Ppv)getSession().merge(ppv);
//instead of getSession().merge(ppv);
getSession().flush();
getSession().clear();
ppv.uvazeks.remove(ppv.uvazeks.iterator().next());
getSession().merge(ppv);
//this flush cause exception
getSession().flush();Problem is that we work with original entity after first merge instead of working with copy returned from merge. Is this forbidden??
This different behavior is probably caused by https://hibernate.atlassian.net/browse/HHH-6361.

Rejecting because only one side of the association was updated. Opposite side still refers to associated entity.
Hi i have two entities in OneToMany relation like this:
@Entity(name = "Ppv") @Table(name = "PPV") public static class Ppv { @Id Long ppvId; @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER, mappedBy = "ppv", orphanRemoval = true) Set<Uvazek> uvazeks = new HashSet<Uvazek>(0); } @Entity(name = "Uvazek") @Table(name = "UVAZEK") public static class Uvazek { @Id Long uvazekId; @ManyToOne @JoinColumn(name = "PPV_FXID") Ppv ppv; }and use case like this:
Ppv ppv = (Ppv) getSession().get(Ppv.class, 1l); getSession().clear(); ppv.uvazeks.remove(ppv.uvazeks.iterator().next()); getSession().merge(ppv); getSession().flush(); getSession().clear(); ppv.uvazeks.remove(ppv.uvazeks.iterator().next()); getSession().merge(ppv); //this flush cause exception getSession().flush();caused exception
