>Taht depends on exactly what you mean by field level validation. If you are referring to domain constraints it si done by the backend database server, if you eman business rules then it is done by the bizobj, and if you mean assistive validation it is done by the front end.

Wow. Ok, I guess I was thinking of a business rule. For example, a work order's done date must be later than its start date.

If you bind the done date control to the object property WorkOrder.dDone, how would you message the user and return the value of the control to the old value when they enter an invalid done date? (The new _ASSIGN methods will handle this nicely . . . ) Thank you.
