Hello, I 've made some custom fields in account invoice form, and i want to make them required or not depended on journal_id. As far {'required':[('journal_id', '=', 1)]} works, but its only for 1 condition. i want to make something like {'required':[('journal_id', '=', 1), ('journal_id', '=', 12)]} but nothing happens. Also I 've tried {'required':['I', ('journal_id', '=', 1), ('journal_id', '=', 12)]} but then it says that "I" is not in the domain. Any ideas?

Also I want to know if there is a way to invoice products without delivery order and manage quantity on hand.

Thanks in advance
