This controller never really worked in the last 3 versions. It was fixed in 11.3 withe9350993cabut broken with refactoring in 12.0 at a higher level with19eacf7d23. It was even worse in 13.0 as it was leading to a traceback: `view_type` field got removed with3cd7ed07a2but this controller was still reading that field. closes odoo/odoo#38355 X-original-commit: a5c4e262449fef03d05d5250e4523832db5fbf00 Signed-off-by: Jérémy Kersten (jke) <jke@openerp.com>
