Here we avoid calling field.get_recursive_orig_value

on all fields because it can be acquired from another
field in context. ie, from a listbox field.
AttributeError is not raised and get_recursive_orig_value
does not exists neither on that field.
So, test condition on meta_type attribute to avoid non desirable side effects.
