Presentation: Exploring the details of APEX sessions (APEX Series)
A 'session' is one of the main features of APEX - it establishes stateful behaviour across pages for each user. Usually, we take a session for granted, but knowing how sessions work in detail can be of great use when debugging errors. How does APEX secure and validate a session and its items? We will see what happens between creation and destruction of a session and how you can interact with it. There are some important differences when assigning a value to an item via Automatic Row Fetch, Computation, Source or Default value. We all struggle with these things from time to time. And what happens exactly when you submit a page, for page processing?
