We have an extremely old application that is now used on 8.5.1 servers. I am enhancing it a bit, but rather than redeveloping, I am just adding to what is already there. I want to add some field validation to a form that has a layout region and is called from an @DialogBox. I have added to the Input Validation and Lotuscript to the Exiting event of the field, but neither seem to work. Is this even possible to do in a layout region?
