I found the cause of the problem in my case.I was making some changes to
the Field Value and Field Property "mandatory" to one field on the
PreSign Event of a Signature. Looks like, next time the form is open the
default values will take place again, then I am changing them again,
which is a change.I changed the Form Properties/Default/Scripting to
Automatically. Now, the problem is solved.Tarek.
