When I push the button to execute 'read_fees_file' I'm getting a error:
--> ' _.detect(self.cache, function (c) {return c.id === id;}) is undefined '

The problem is that in the function (read_fees_file), I delete the current links
of the one2many 'field_fees_ids' and update it whith the new one's, who's creating
new id's in the 'supplier.import.field' object but those id's aren't available when
creating/refreshing the new view.
