Hi everyone. I want to make table under the <page> like order lines in sales. But now, I will add like that in payroll module. When I'm using <notebook>, my new page doesnot show. I used odoo v10. Here my code :

my .py

from openerp import models, fields, api

class PurchaseOrder(models.Model):

_inherit = 'hr.payslip'

     gaji_pokok = fields.Integer(string="Gaji Pokok")

     t_lembur = fields.Integer(string="Tunjangan Lembur")

Here my xml

<?xml version="1.0" encoding="utf-8"?>

<openerp>

<data>

<record id="view_hr_payslip_inherit_form_extended" model="ir.ui.view">

<field name="name">hr.payslip.inherit.form</field>

<field name="model">hr.payslip</field>

<field name="inherit_id" ref="hr_payroll.view_hr_payslip_form" />

<field name="arch" type="xml">

    <xpath expr="//page[1]" position="after">

         <form string="tes_table" colspan="4" nolabel="1">

             <notebook>

                 <page string="Pendapatan Karyawan">

                     <separator string="Tes Hasil"/>

                         <group col="4">

                             <tree colspan="4" nolabel="1" string="Tunjangan Gaji">

                                 <field name="gaji_pokok"/>

                                 <field name="t_lembur"/>

                             </tree>

                         </group>

                     </page>

                 </notebook>

             </form>

         </xpath>

       </field>

     </record>

</data>

</openerp>

Anyone can help me please about this?
