Showing :

ValidateError Error occurred while validating the field(s) arch: Invalid XML for View Architecture. Try all other stackoverflow solution or similar solution. But still stuck.

Answer 1

update your xml file,

  <?xml version="1.0" encoding="utf-8"?>
  <openerp>
  <data>
  <record model="ir.ui.view" id="product_extension_product">
    <field name="name">product.normal.form</field>
    <field name="model">product.product</field>
    <field name="inherit_id" ref="product.product_normal_form_view"/>
    <field name="arch" type="xml">
        <xpath expr="//field[@name='partner_id']" position="after">
            <field name="product_extension_style_number"/>
            <field name="product_extension_where_used"/>
            <field name="product_extension_est_yield"/>
            <field name="product_extension_cost_dz"/>
        </xpath>
    </field>
 </record>
 </data>
 </openerp>

Hope this will give you desired output. Don't forget to update your module.

Answer 2

There is no field called partner_id in that form you r inheriting & also inherit must be module.xml_id not view name

See for example:

<record model="ir.ui.view" id="product_extension_product">
    <field name="name">product.normal.form</field>
    <field name="model">product.product</field>
    <field name="inherit_id" ref="product.product_normal_form_view" />
    <field name="arch" type="xml">
        <xpath expr="/form/sheet/notebook/pages[@string="Information"/group/group/field[@name='type']" position="after">
            <field name="product_extension_style_number" />
            <field name="product_extension_where_used" />
            <field name="product_extension_est_yield" />
             <field name="product_extension_cost_dz" />
        </xpath>
    </field>
</record
