In Laserfiche Forms (we use LF Forms 11), I noticed that read-only fields do not trigger lookup rules. I have a read-only field that I would need to trigger a lookup rule and it doesn't, however, as soon as I uncheck the read-only checkbox it starts working.

Is there a way to make a lookup rule work with read-only fields ? My use case here is I need users to enter a customer first and last name (as 2 separate text fields) and this would dynamically build a read-only field for the customer full name (as "Firstname Lastname"). I need to check if this full name already exists in a customer table to avoid duplicates.

I do have a workaround which is to make the "Full Name" field read-write but hidden, however I would prefer to be able to show it in the form.

Thank you !
