i have this structure class:



public class A 
private list<B> b;


public class B
public class B1 extends B
public class B2 extends B


At the controller:



@RequestMapping("/A")
public ModelAndView getA()
model.addObject("a", a);



This method return the list with all B1 and B2 to the view and all ok.



But when i try submit the form:



@PostMapping("/saveA")
public ModelAndView saveA(@ModelAttribute A a, BindingResult bindingResult)


the specific values ​​of each class dont save.



Is there any way to do this?
