> Hi,
> I am using Struts and am trying to display and edit a list of objects using
> nested iterate. However when I submit the form, the form is not getting
> populated causing the following exception.
> I am getting this exception when I set the scope of the action to request.
> However the same code is working properly when I set the scope of the action
> to session instead of request.
> java.lang.NullPointerException
