Hello,

I have a custom field value that doesn't change, even if I set a fixed value:

    def set_support(self):
        self.id_selected_support = 3
        _logger.info(self.id_selected_support)

When the method is called, the logger show me 0, instead of 3.

This custom field is set on sale.order.line model. So, when I create a new sale.order, no sale.order.line is currently stored on DB. I cannot write.

This method is called from another model. I have multiple lines in a Many2many field, and when a checkbox is updated in one of these lines, it calls the set_support method of sale.order.line.

What could be the problem ?
