[12.0] Problem when creating a return to customer

[marcgendron-dyze]

When I click on the button Return to customer, I choose a date, then I click on Deliver, it sends a python error. I don't understand why the date_expected is readonly. The move_form is in draft (I logged it just before the error) so It should not be read-only. Does any one had the same issue?

Hi, @marcgendron-dyze . Can you reproduce the error on a runbot a give some complete steps to reproduce it?

[marcgendron-dyze]

@chienandalu I just tried on the run but. It does not the error. So it must be something in conflict on my installation. I will continue ton investigate, but I'm new on odoo, and I have a hard time to understand why I get this error. The declaration in stock\model\stock_move.py seams to say that it should only be readonly if the state is Done. I verified the state and its 'draft'. If you have any cue for me, I would appreciate.

Thank you.
