I created a workflow with "Request Approval" workflow action in my acceptance server. This action has a custom task form. Later I exported and imported this workflow into production server. When tried to publish, the "Request Approval" action shows a message "The form has control(s) that have incomplete property settings" and not allowing me to publish the form.
I tried open and save each and every field from the custom task from and also make sure the fields are connected to respective list columns (wherever applicable). But still no luck.
