Cast to entity to the correct specialization.
, 8. What should you do if the Object type decision is empty?:

reusable microflow, which increases the consistency and
maintainability of your app.

when the entity in question isn't a true specialization of the
generalized entity and/or the generalized entity's properties are
not required when dealing with the entity in question.
11. Why is creating a new entity and making it a specialization
of the FileDocu- ment or Image entity preferred over using
original entities?: The original entities are part of the System
module, which makes them ineditable.

that entity's side of the association.
