In Odoo version 8, I noticed that wizards do not behave the same as in v7. If the wizard have some fields displayed in its view, and a button to execute an object method, the fields are not written before calling the method, but after. In v7, clicking on a button would result in a write of the fields values, and then calling the method, which is more handy in my opinion.
Do you know a reason for this change ? And do you know how we could force the wizard to persist the changes made in the view before executing a button's click method ? I would like to have the latest changes available in the method when it is called.
