Hello,

I'm stuck to populate a wizard and I'm completely lost on the way to do that.

Until know, I've created a custom button on the stock module, view_picking_form record with an inherited model (see views.xml). I also know how to create a custom wizard (wizard.py wizard.xml).

But what I do not know is how to populate it with the list of products fields (product_id, product_qty, qty_done) that are linked to the active view. I'm working with the new API on Odoo 10 and couln't find the method to do that. Odoo always tells me it doesn't know the fields I want to pass and they don't display on the wizard.

Can anyone help me on that please ?

views.xml

            <record id="view_picking_form_inherit" model="ir.ui.view">
                <field name="name">stock.picking.form.inherit</field>
                <field name="model">stock.picking</field>
                <field name="inherit_id" ref="stock.view_picking_form"/>
                <field name="arch" type="xml">

                        <div class="oe_right oe_button_box">

                            <button string="Open Wizard" name="%(action_wizard)d"
                                    type="action" class="oe_button oe_form_button oe_highlight"
