I am having the same problem. When a digital signature is applied, I get
an error pop-up for all of the Text Fields that are set as "required."
It will cycle through each one successively two times within each
"Group." It does this even when the required fields are completed. I
don't have the error boxes checked for scripting or validation pattern.
I get the error pop-ups in the same fashion when I try to close the
document as well. Note that this only happens with text fields and not
date, stat...
