I’m trying to create a custom screen/graph that will have a Complete action (like the existing Project screen) but I can’t figure out how the actual Status column is getting changed on the existing or how it is persisting after this action runs.

In my custom screen/graph I am having to explicitly call Persist() and the status code itself does not change to Completed.  I wasn’t able to step any further or find any events that are setting the status and/or calling Persist()

UPDATE: I think the answer is Workflow (which I have not delved into much)  I see there is a transition from Active to Complete.  Does this implicitly cause the status to change from the action complete trigger?  And, if so, does this also fire Persist()?
