title: why is model-driven action preferred over object backed bean properties
body: <p>i am learning struts2 from the book struts-2 in action. they say that for transferring data onto objects model-driven actions is preferred over object-backed beans properties. </p>
  
  <p>can some1 explain me why they say so?</p>
  
  <p>does the reason have something to do with the need to mention reference name in the view layer</p>
