RE: Date Field Validation

Here is how Appian works for a field which is required.

1. When page loads and a required field have null value then it does not show default required validation unless user hit on submit button.

2. When page loads and a required field having some value and if you clear it off then also it does not show default required validation unless user hit on submit button.

However, we can customize when to show validation based on validation group (Use Validation Groups for Buttons with Multiple Validation Rules - Appian 23.3)

Coming to your question: We can't show validation on clear click as that's not a button its just a part of date field.

Business perspective: Why your business need that, Any how if user clear the data and try to submit, Appian will throw the validation??

The issue ist, that for "Not empty" implementation the "required" paramater is designated to solve it. required = true and a button widget with the default value for "valdite" (true) results in an evaluation aka null check.
Default error message:

is that not sufficient?
