How low-level of an execution flow are you looking for? At a very high-level, your application is calling a servlet to display a simple form, then when the form is submitted, another servlet is executed which gets a reference to the PersistenceManager using a PersistenceManagerFactory singleton, uses it to store the data sent with the request to the servlet, and then prepares and returns the response. I'll have to see your domain classes and persistence code to determine why you're seeing null values. One thing you can do is, when running locally, open http://localhost:8080/_ah/admin in your browser. This should load a local data viewer, and you can see how the data is stored internally.
