Error when deleting sale return - no attribute "parse" - Tryton 3.2
When I make a return for an sale and confirm the wizard I have a view of an return sale. When I delete this return sale now, I have an empty grey sale view form.
When I now change the view (to tree) I get this error:
"NoneType" object has no attribute "parse"
