This set works for me:


WHEN OBJECT ADDED CALL sqlInsertProduct(,, rate=self.rate, last_payment=self.last_payment, 

WHEN OBJECT CHANGED STORE email, rate, last_payment, primary, services 
USING sqlUpdateProduct(,, rate=self.rate, 
last_payment=self.last_payment, primary=self.primary,


WITH QUERY lookup_product( COMPUTE 


Where each of the queries does the 'right' thing. You generally don't
want to attribute that you are using for the 'id' to be present in any
propertysheet since that property will come from the ZClass and fool
the 'Virtual' instance machinery. Note that if you don't specify "STORE"
on the WHEN OBJECT CHANGED line then you'll have trouble with the
Rack not being able to find attribute storage for the changed

Good Luck!
