[send in copy on Struts-dev list]
In ActionServlet (Struts 1.0.2) you can read that formBean object found in
scope is compared to the form name declared in ActionMapping by testing
class name, not testing it using an "isInstance" or any other reflection
mecanism that could allow using inheritance or abstract FormBeans.
instance = (ActionForm) session.getAttribute(attribute);
...
className = formBean.getType();
...
className.equals(instance.getClass().getName())) {
Can any Struts developper explain if there is a technical reason to this
limitation ?
