经修改和测试后能用的代码,谢谢大家指导.
6.1测试成功,如果已经建立的表单,需要修改表单里的产品数量(任意)并保存才能显示新的计算产品量

回的值还是不对,还是0.00,请指点

添加return res[order.id]=value? 还是别的,请解释下,不太明白,谢谢

sale_order() 

sale_view.xml
<xpath expr="//field[@name='amount_untaxed']" position="before">
<field name="total_quantity" />
</xpath>

新添加的total_quantity field 回值显示0.00. 无报错,问题出在那里,请有经验的解答下, 求的值是全订单的物品数量值.谢谢
