I have been using the nested tag for a moment and it is great for displaying nested information but I got a problem when submitting information using the tag. When I submitting the form with nested tag, it always comes out with null pointer exception during populating values to the bean if I do not instantiate all the child object and array size in the bean's constructor. Since I do not know the actual size of the object before those properties can be populated, this make me need to set the MAX of the array size and always instantiate them in the bean's constructor, is there better method for doing that?
