Hello,

How is it possible to first persist and after that evict object from the same session in Hibernate?
I cannot afford to use flush on session before evict!

In my application user can open new panel A for inserting A in database.
Then in panel A user can click to open new panel for adding bean B in database and also to
open new panel C for adding bean C from panel B.
What i need is to persist A and B when user cliks to open panel C because bean C
has foreign key to bean B and B has foreign key to A.
I need to flush session only when user clicks OK on panel A.
However if user clicks Cancel on panel B i need to evict bean B from session because i don't
want to persist bean B. However Hibernate throws exception
possible non-threadsafe access to the session when i try to evict
already persisted object. I cannot use flush beacuse it will insert B into database.

Can someone help me about this.

After some tests i find out that evict does not do what i want.
E.g.
session.setFlushMode(FlushMode.MANUAL);
Stock stock = new Stock();
stock.setStockCode("4715");
session.save(stock);

session.evict(stock);
session.flush();

This will insert stock object in database even evict is called after save.
Is there any way to remove already persisted object to session to not be
saved when session is flushed?
Let say i needed to create and persist bean in session and afterwards i decided not to
save that bean in database on session flush. Is it possible?

Any help?

No way.
All changes till save method will execute , but the changes after SAVE won't goes to database

I can see that, but what is then proper way to handle this?

I need to persist object A in one panel to open new panel from first panel (beacuse bean in new panel
have foregin key to bean in first panel) and so on.
Now if user decide to insert beans in sub-panels and to not insert bean in first panel all
persisting should be discarded without any insert in database and that is ok beacuse
i am calling flush only on first panel. But problem is when user decite to not insert
beans in sub-panels and to insert bean in first panel. As i flush session here, all
previously persisted objects will be in database and i want to avoid this.

Any ideas?
