            </form>
        </field>
    </record>

What I want is t call this view from a wizard, with steps, so every 'x' field quantity can be filled on every step, this is my wizard code:

def action_next1(self, cr, uid, ids, context=None):
  #your treatment to click  button next 
  #...
  # update state to  step2
  self.write(cr, uid, ids, {'state': 'step2',}, context=context)
  #return view
  return {
        'type': 'ir.actions.act_window',
        'res_model': 'bsi_production_order',
        'view_mode': 'form',
        'view_type': 'form',
        'res_id': this.id,
        'views': [(False, 'form')],
        'target': 'new',
         }

def action_next2(self, cr, uid, ids, context=None):
  #your treatment to click  button next 
  #...
  # update state to  step2
  self.write(cr, uid, ids, {'state': 'step3',}, context=context)
  #return view
  return {
        'type': 'ir.actions.act_window',
        'res_model': 'bsi_production_order',
        'view_mode': 'form',
        'view_type': 'form',
        'res_id': this.id,
        'views': [(False, 'form')],
        'target': 'new',
         }

def action_next3(self, cr, uid, ids, context=None):
  #your treatment to click  button next 
  #...
  # update state to  step2
  self.write(cr, uid, ids, {'state': 'step4',}, context=context)
  #return view
  return {
        'type': 'ir.actions.act_window',
        'res_model': 'bsi_production_order',
        'view_mode': 'form',
        'view_type': 'form',
        'res_id': this.id,
        'views': [(False, 'form')],
        'target': 'new',
         }

def action_previous1(self, cr, uid, ids, context=None):
  #your treatment to click  button previous 
  #...
  # update state to  step1
  self.write(cr, uid, ids, {'state': 'step1',}, context=context)
  #return view
  return {
        'type': 'ir.actions.act_window',
        'res_model': 'bsi_production_order',
        'view_mode': 'form',
        'view_type': 'form',
        'res_id': this.id,
        'views': [(False, 'form')],
        'target': 'new',
         }

def action_previous2(self, cr, uid, ids, context=None):
  #your treatment to click  button previous 
  #...
  # update state to  step1
  self.write(cr, uid, ids, {'state': 'step2',}, context=context)
  #return view
  return {
        'type': 'ir.actions.act_window',
        'res_model': 'bsi_production_order',
        'view_mode': 'form',
        'view_type': 'form',
        'res_id': this.id,
        'views': [(False, 'form')],
        'target': 'new',
         }

def action_previous3(self, cr, uid, ids, context=None):
  #your treatment to click  button previous 
  #...
  # update state to  step1
  self.write(cr, uid, ids, {'state': 'step3',}, context=context)
  #return view
  return {
        'type': 'ir.actions.act_window',
        'res_model': 'bsi_production_order',
        'view_mode': 'form',
        'view_type': 'form',
        'res_id': this.id,
        'views': [(False, 'form')],
        'target': 'new',
         }

And this is the respective view:

        <field name="model">bsi.production.order</field>

        </field>

Now, if I want to open this wizard view, it just shows an empty white form, also, the vey same thing is happening with the non-wizard view, this are the menuitems and actions

For wizard:

 <record id="action_prod_order" model="ir.actions.act_window">
        <field name="name">Production Order (Wizard)</field>
        <field name="type">ir.actions.act_window</field>
        <field name="res_model">bsi.production.order</field>
        <field name="view_type">form</field>
        <field name="view_mode">tree,form</field>
       <field name="view_id" ref="view_wizard_prod_order_form"/>
       <field name="target">new</field>
 </record>
 <menuitem action="action_prod_order" id="menu_mrp_production_order_action_1"
        parent="mrp.menu_mrp_manufacturing" />

And for form view:

 <record id="mrp_production_order_action_2" model="ir.actions.act_window">
        <field name="name">Production Orders</field>
        <field name="type">ir.actions.act_window</field>
        <field name="res_model">bsi.production.order</field>
        <field name="view_type">form</field>
        <field name="view_mode">tree,form,calendar,graph,gantt</field>
        <field name="view_id" eval="False"/>
        <field name="context">{}</field>
        <field name="help" type="html">
          <p class="oe_view_nocontent_create">
            Click to create a production order. 
          </p><p>
            A production order...
          </p><p>
            Production orders are usually proposed automatically based
            on customer requirements or automated rules like the minimum
            stock rule.
          </p>
        </field>
</record>
<menuitem action="mrp_production_order_action_2" id="menu_mrp_production_order_action_2"
        parent="mrp.menu_mrp_manufacturing" />

Any ideas?

Answer 1

I think the problem is in your action

         <field name="view_mode">tree,form</field>

You are showing your record In tree view in a popup this not allowed in odoo. Generally the tree will be just a simple bare and when you click on it than the record are loaded this is in odoo 10.

Just use form mode

And make sure you status field has a default value too.
