We have several Forms processes where the end user types in a value and then a lookup is performed and populates other fields on the form, usually fields within a table row.

End users seem to get confused after they have typed in a value, but none of the fields get populated that they are expecting to because they don't know if the lookup didn't return something or if it is still performing the lookup.

It would be great if when the lookup didn't return any rows that a message could be displayed on the form. It would be even better if the process admin could customize the message, much like creating an error message.
