"Must use setCurrentEntity if select is not done through database"

After doing an insert of an account I want to change the "login" so I
call "account.update".  But it fails with a message of "Must use
setCurrentEntity if select is not done through database"... ?????
Anyone have a clue what his means?  

Otherwise, if it is not possible to change "login" what is the purpose
of account.update?
