In a form I have some fields, one of these is an eMail that I would like to validate but only if the user enters it, meaning that it is not a mandatory field, I have not found a way to do it..
Has anyone succeeded?
Another thing, the fields have the "Initial Value" property and I tried to set this value with a json path but it does not work, I did a debug and I saw that FF assigns the value before executing the query that I put on the initialization action!
Any trick to overcome this problem?
