I have a situation where I want to have an ActionForm (let's say AutomobileForm) w/
only 1 variable (Automobile). If the Automobile class's get/set parameters were all
run of the mill types (String, int, boolean, etc), I would normally just have a method
called 'getAutomobileObject()' inside
If I understand what you're saying, (using the previous Automobile example)
you would have something like
// THE ORIGINAL VALUE CLASS
public class Automobile
{
private CarType carType = null;
public CarType getCarType(){ return carType; }
public void setCarType(CarType ct)
