In my form, I have some mandatory fields and a button which will open a popup.
Popup has YesNoCancel buttons at the bottom (not custom buttons)
When the user clicks the 'No' button of the popup, I have to throw validation error on the mandatory fields of the parent form (The form in which the button is present which calls the popup).
