The create link goes to '/person.html' which is mapped to the person flow. The search link still goes through the PersonController.

The edit link goes to the person flow (ex: '/person.html?id=1'). The flow will look up the person record based on the id request parameter.

The form:form element just needs to have it's modelAttribute set to correspond to where the flow put
the Person instance. The save and cancel buttons specify which event id they are associated with for this step in the flow.
This value should match the flow's transition element's on attribute.
The link to add an address goes to the address subflow. If there are any addresses, they are displayed in a table with an edit next to each record. There is also a delete link if the user is an admin.
The top of the page has a 'messages' div which can display a status message key or any Spring bind errors. This is where Spring Web Flow will store any errors for automatic validation performed based on a method on the model instance or a bean. In this case, there is a personValidator bean that validates if the first and last name are not blank.

The 'messages' div at the top of the page can display a status message or any Spring bind errors. The validation for address is
in a method in the Address class. The method in this case is validateAddressForm(MessageContext context).
It is for the 'addressForm' view-state so the method name should be 'validate' + ${viewStateId} and take
a MessageContext as a parameter.
