I've searched all over the place for a solution to add notifications inside the edit form, whenever there's a problem on update, but no matter what I tried , it's either the edit form is open (which is good) but no notification apears and the data is refreshed to what it was before I pressed the update button,
or, the edit form get closed and still, no notification .
I used this example :Edit Form Types
Can someone explain to me, how to get is to work? there's no meaning to the update if I can't validate part of the data
