Adrian Torres 3f4f77fd9d [REF] *: adapt code to new related default behaviour
This commit adapts the business code to changes introduced by
the parent commit in order to keep the same behaviour as before.

All readonly=False fields will have to be checked afterwards to confirm
that the business case requires write access to the source field.
