Autofill Using CDD Not Resetting Fields After Choosing "Please select"

[hominid4]

Hi. I have a simple form that has a Db Join element, then a CDD watching that element, and then based on the CDD selection (observed field) it autofills several fields using the Autofill plugin. All of that works fine.

After I choose from the CDD and it autofills the fields, and if I then choose "Please select" from the CDD the form refreshes but keeps the autofilled values of the previous selection. Same if I choose a different Db Join selection, which resets the CDD, but retains the previous autofilled values.

Is it possible to have the autofilled fields empty out if "Please select" is chosen from the field to observe?

Thanks!
