Drees,

If you used the wizard, the Save and Close buttons(on footer) will automatically close the pop up. If you are doing a call of method from wizard, you must return {'type': 'ir.actions.act_window_close'} and your purpose will be served.

If you used dialog box from JS, you must use window.close for that.

How did you manage to add the pop up?

Thanks.

Hey,

I had the same issue and I solve it by adding footer to the form view :

<footer>
    <field name="id" invisible="1"/>
    <button string="Create" name="action_close" type="object" class="btn-primary"
            attrs="{'invisible': [('id', '!=', False)]}"/>
    <button string="Save" name="action_close" type="object" class="btn-primary"
            attrs="{'invisible': [('id', '=', False)]}"/>

    <button string="Cancel" class="btn-secondary" special="cancel"/> footer>

then In my model i define the function action_close : 

def action_close(self):
    return {'type': 'ir.actions.act_window_close'}

Thanks for the answer friend.

Here is my code:

def edit_data(self, cr, uid, ids, context=None):

mod_obj = self.pool.get('ir.model.data')

res = mod_obj.get_object_reference(cr, uid, 'test_paie', 'test_paie_form')

momo_id = self.read(cr, uid, ids,['id','year','period','employee_id'])

print("momo_id =" , momo_id)

ref_id = self.check_data(cr, uid,momo_id[0]['employee_id'][0],momo_id[0]['year'],momo_id[0]['period'])

return {

'name': 'New Data',

'view_type': 'form',

'view_mode': 'form',

'view_id': [res and res[1] or False],

'res_model': 'test_paie',

'context': {'default_employee_id':momo_id[0]['employee_id'][0],'default_period' : str(momo_id[0]['period']), 'default_year' : str(momo_id[0]['year'])},

'type': 'ir.actions.act_window',

'nodestroy': True,

'target': 'new',

'flags' : { 'action_buttons' : True,},

'res_id': ref_id,

}

return {}
