I have two objects from OpenEdge service: Customer and Invoices; and a relation (1 to many) between them.
On the Invoices Edit page I have an external lookup field for selecting the Customer info.
I have also implemented in OE business logic validations triggered on Save. If something is not ok a messages is trowed up from business logic. When this happens the value of the lookup field (customer id) is lost.
This did not happen on the old UI.
Do you know what may cause this?
See below some screen shots.
