I have had several scenarios where it would have been nice to be able to use a business rule to clear the content of a field on the form.
I currently have to choose between either doing it via a realtime Work flow. I trigger the workflow by a forced save event on the field changes that should trigger the clear action). Alternatively I found a way of doing it by creating a hidden "dummy" field of the same field type on the form. I then take the empty value of that field and insert it in the field that I want cleared. Neither solution is very nice. A Clear Action or allowing me to set an empty value on the Set Field Value action would be much appriciated. Thanks
