Since commit e17c2135cb24aa600eeff9426b93665537a33d00, if an error is thrown during the "save" of X2ManyFieldDialog, the buttons are enabled(). So the patch on X2ManyFieldDialog in question_page_one2many_field.js is no longer useful. So we're going to remove it. closes odoo/odoo#139550 Signed-off-by: Aaron Bohy (aab) <aab@odoo.com>
