What will happen within the scope of a single transaction, the FlushMode is changed.

Here is my pseudo code.

//*************
Txn Begin;

sesseion.setFlushMode(Manual);

do some query;

sesseion.setFlushMode(AUTO);

update an entity's properties; // dirty entity

sesseion.setFlushMode(Manual);

do some query;

// No call on session.flush();

commit Txn;
//****************

Will the updates be committed?
