You need to set the employee in the Account (you need a setEmployee() method in Account).

See,

Thank you for the reply...
I am trying to understand why it works only from the owner side in one to one relationships...
I will read again your link...

so doing ac.setemploye() only instead of e.setaccount it would work?
i ll try...thanks...
