I want to add discount to the tree in account.invoice.form view.
I'm just wondering why it is not shown. I set invisible false but still no effect.
...
<page string="Invoice Lines"> <field name="invoice_line" nolabel="1" widget="one2many_list" context="{'type': type}">
<tree string="Invoice Lines" editable="bottom"> <field name="product_id" on_change="product_id_change(product_id, uos_id, quantity, name, parent.type, parent.partner_id, parent.fiscal_position, price_unit, parent.currency_id, context, parent.company_id)"/>
<field name="name"/> <field name="company_id" invisible="1"/>
<field name="account_id" groups="account.group_account_user" domain="[('company_id', '=', parent.company_id), ('journal_id', '=', parent.journal_id), ('type', '!=', 'view')]" on_change="onchange_account_id(product_id, parent.partner_id, parent.type, parent.fiscal_position,account_id)"/>
<field name="account_analytic_id" groups="analytic.group_analytic_accounting" domain="[('type','!=','view'), ('company_id', '=', parent.company_id)]"/>
<field name="quantity"/>
<field name="uos_id" groups="product.group_uom" on_change="uos_id_change(product_id, uos_id, quantity, name, parent.type, parent.partner_id, parent.fiscal_position, price_unit, parent.currency_id, context, parent.company_id)"/>
<field name="price_unit"/>
<field name="discount" invisible="0"/>
<field name="invoice_line_tax_id" widget="many2many_tags" context="{'type':parent.type}" domain="[('parent_id','=',False),('company_id', '=', parent.company_id)]"/>
<field name="price_subtotal"/> </tree>
...
I tried <field name="discount"/> and <field name="discount" invisible="0"/> but still nothing, no errors.
What could it be?
