Stateless -> insert into FormA -> Field Actions don't happen?

Stateless -> insert into FormA -> Field Actions don't happen?

A stateless form has script that inserts a row into FormA.  Very cool.

FormA has script in  Field Action -> On User Input.  But, when the data comes in via the Stateless Form, the Field Actions don't kick in.  Should they?

Or, do I need to  fetch the associated values before I do the insert into FormA???
