Hello, I created a wizard and have a many2one field that is related to the sale.order. I would like to pass in the sale.order active id to the many2one field that is on the wizard.

In the Sale Order form I have a button with the type set to action, and I am using the context to pass in the active id of the sale.order to the sale_order_id field

<button name="%(action_view_wiz_pay_auth_net)d" type="action" string="Pay with Authorize.net" context="{'sale_order_id': active_id}" class="oe_highlight" />

Here is my xml wizard action:

<record id="action_view_wiz_pay_auth_net" model="ir.actions.act_window">
        <field name="name">Credit Card Info</field>
        <field name="res_model">sale.auth.net.payment</field>
        <field name="view_type">form</field>
        <field name="view_mode">form</field>
        <field name="view_id" ref="view_wiz_auth_net_payment_form"/>
        <field name="target">new</field>
    </record>

here is the wizard form:

<record id="view_wiz_auth_net_payment_form" model="ir.ui.view">
        <field name="name">wiz.auth.net.payment Form View</field>
        <field name="model">sale.auth.net.payment</field>
        <field name="arch" type="xml">

I have another many2one field partner_id that is related to res.partners on my wizard which actually loads the partner that is related to the sale.order. Im not sure why the partner_id is loaded, but not the order_id in the wizard. Can anyone explain why? Thank you
