In the order flow there are three order flow transition types - manual, auto and on event. What is the difference between them?
Manual - transition is made on manual button click. On event and Auto - on transition the flow handler assigned is attempted to be executed, it is done automatically. As a result success/failure/exception is returned. If the transition is On Event then there is a database commit in case of exception. If the transition is Auto and exception is received, that means the transaction rollback to the previous status.
