Before this commit, coming back on a view when in 'debug=assets' would erase the previously loaded favorites with an 'undefined' value. This was due to an incorrect cache invalidation mechanism in the DataManager's load_views' method. Now the views and filters caches are properly loaded if any of them has been invalidated. closes odoo/odoo#48085 Signed-off-by: Aaron Bohy (aab) <aab@odoo.com>
