I'm trying to extend the registration form in combuilder for national number (Belgium) . I need to check the date part of the national number with the date of birth on screen. Is there a way to check this inside the user plugin with ajax? I already created my own class for the item type and the validation logic is working, I just can't reach the other values in the form.
