As I understand it, if I set sessionForm == true in a SimpleFormController, then when the form is submitted, the formBackingObject will be retrieved from the session and used in the onSubmit method, rather than being created from a call to formBackingObject().
I am puzzled - I have set sessionForm == true in a SimpleFormController, but still get a call to formBackingObject() when the form is submitted. I assumed that the storing and retrieving of the object in the session was taken care of automatically, but perhaps not? Am I missing something? Can someone explain please what might be going on here?
