Issue - Install Dashboard & Sales - Add a graph & a list to the dashboard - Go in the dashboard Rendering ok - Click on a list item - Go back with the breadcrumb Traceback Cause When going back with the breadcrumb we retrieve the previous view controller. https://github.com/odoo/odoo/blob/9400059073d7401789eb1a60d6a0ec6f58dfc66b/addons/web/static/src/js/chrome/action_manager_act_window.js#L457 By restoring the board controller, we restore all the subcontrollers too. But the actual board renderer is re-creating controllers. This creates inconsistencies with the view. Solution Remove the restored controllers OPW-2232713 closes odoo/odoo#49728 X-original-commit: 4f3d818052d689da762d8afbf1789daaa3d39821 Signed-off-by: Jason Van Malder (jvm) <jvm@odoo.com>
