Cannot persist in final state for MassTransitStateMachine

[tianyingwang]

I have a MassTransitStateMachine with Automatonymous.

Several states such as Process and Completed. I can save Process state into database so I think my SagaRepository is setup OK, however cannot save the completed state or final state into database.

Below is the piece of code, I can see in my debugger that the PreprocessForComplete() function get called, so I assume the Finalize() should be called. But my database still stay in Process State.

Anyone could give me some suggestions where I should check?

Thank you so much.

            DuringAny(

                ..........

                ..........

                When(ReadyForComplete)

                    .Then(PreprocessForComplete)

                    .TransitionTo(Completed)

                    .Finalize()

                    );

Do you have 

SetCompletedWhenFinalized();

?

Alexey, thank you for your suggestion.

I did test with and without "SetCompletedWhenFinalized();", still cannot persist state into table.

Seems it will take some TransitionTo, but not the others, I double check the correlationid, all matched well. Very strange.

I am using NHibernate, anyone experience this kind of problem?

Finalize() is the same as TransitionTo(Final), so the TransitionTo(Completed) isn't really doing anything for you, unless it's part of a composite event.

With NHibernate saga persistence, completed sagas are removed. If you want to have your saga in some custom "Completed" state at the end, and not being removed, you can just remove "Finalize()". 

I believe you are making two conflicting transitions and this creates issues for you.

Thank you Alexey. I cannot get to test since our QA is testing for a release soon. I am going to build a small project to test your suggestion. Thanks again.

Quick question Chris,

Do you know which api call trigger the save the state change into database?  Is that TransitionTo(State)? 

Thank you.

I am not Chris but each persistence is a filter. It retrieves one or more instances and send them further. Each Send causes RaiseEvent in Automatonymous, which triggers all During/When combinations that match the received event. When all processing is done, the new saga state is persisted at once.

[Chris Patterson]

Alexey is correct, the flow is:

(message received)

(saga instance loaded)

(all state machine processing performed)

(sage instance saved)

(message receive complete)
