This article explains the order the various elements of Flow are called.

Process

1. Entry Pipeline calls JS function
2. (optional) JS function loads data
3. JS function calls DisplayForm pipeline
4. DisplayForm Pipeline sends page to visitor
5. Visitor submits page
6. Continuation Pipeline returns to JS
7. JS validation, loop to #3 if necessary
8. JS saves data
9. JS calls Exit Pipeline
10. Exit Pipeline sends confirmation to visitor
