Lets say that i have the following button
<button string="Set landing page" nolabel="1" type="object" name="set_landing_page" class="oe_highlight" confirm="Will set landing page and go to the selected page, 
 It can be changed later in settings or introduction module"/>I want to return the ir.actions.act_window
And i have some code to identify the view and return it
....The view is possible to open, but it is not possible to refresh the menu
landing_page = landing_page.read()[0]
landing_page['tag']='main' #Is set to remove the breadcrumbs
return landing_page
asd
Are trying
return { 'type' : 'ir.actions.act_close_wizard_and_reload_view' }
