Ok.

The sequence can be: get_transaction.commit()
                     con.sync()
                     <modify object
                     get_transaction.commit()

This acts like a lock, no?

Need I to do a get_transaction.commit() or can I do a
get_transaction.commit(1)?

A lot of thanks.

Greetings
