There are a couple of problems in your code...
The big problem I see is that you are mapping your form to an object in
your template and then trying to access it with the DEFAULT_KEY in your
action class.
The second problem may be a misunderstanding in how to use intake. In
your screen class you pass a Customer object into the context. This
only makes sense if you are trying to populate the form with the values
of that object (for example if the form is to update a customer's info)
which your arent since the object is empty and you create a new object
in the action class. Since the purpose of the form seems to be to
populate new customer objects, then map the form to Default, remove the
code in your screen class that places the customer object in context,
and leave your action class the way it is.
To put it another way, i think you confused the purpose of mapTo( object
). This is not to map the elements of the form to fields of a class,
thats whats in intake.xml. This is to map the values of an existing
object to the elements of a form.
