How to clear validation icons after form submit success event

What I'm triying to understand is where is your upsert form placed?
In a modal or in a container/column set as DataDetail inside your actual page?

In both cases the form isn't always visible and waiting for user's input for submittion...

So if you follow these steps you described here:

How is posssible the form is still active (waiting for user's input and submission) after it is successfully submitted, reset and obviously datadetail set to null etc...?
