There is no mechanism in the smart-rules.pl to indicate that information entered was invalid. The rule is simply created omitting invalid information. For example, if you create a rule and put an invalid date in the hard due date, the rule is created, but the date is omitted. There is no warning that it changed what was entered, or what was changed. Christopher
I don't think it's possible to enter invalid dates with flatpickr, at least I didn't manage to, but there are also other fields like the numeric ones, that we could validate.
