Hello,

I'm trying to do a wizard. But when I try to launch it on OpenERP, I have a blank view. I think I miss something, but I don't know what.

XML: <openerp> <data> <record model="ir.ui.view" id="view_staff_pay_push_form"> <field name="name">staff.pay.push.form</field> <field name="model">staff.pay.push</field> <field name="type">form</field> <field name="arch" type="xml"> <form string="Pay Push" version="7.0"> <field invisible="1" name="state"/> <group states="init"> <field name="user_id"/>
</group> <group states="defineAmount"> <field name="amount"/>
</group> <footer states="init"> <button name="action_next" string="Next"/> </footer> <footer states="defineAmount"> <button name="action_previous" string="Previous"/> </footer> </form> </field> </record> <record model="ir.ui.view" id="view_staff_pay_push_tree"> <field name="name">staff.pay.push.tree</field> <field name="model">staff.pay.push</field> <field name="type">tree</field> <field name="arch" type="xml"> <tree string="Pay Push" version="7.0"> <field name="user_id"/> <field name="amount"/> </tree> </field> </record> <record model="ir.actions.act_window" id="show_Field"> <field name="name">Pay Push</field> <field name="res_model">staff.pay.push</field> <field name="view_type">form</field> <field name="view_mode">tree,form</field> </record> <menuitem name="Field" id="menu_staff_pay_pushs" sequence="49" parent="menu_staff_options" action="show_Field" groups="group_staff_management_in_charge"/> </data> </openerp>

Python file:

from openerp.osv import osv, fields
from openerp.osv.orm import TransientModel

class staff_pay_push(TransientModel):
_name="staff.pay.push"
_columns={
    'user_id':fields.many2one('res.users', 'User', relate=True),
    'amount': fields.float('Amount', readonly=False),
    'state': fields.selection([('init', 'init'),('defineAmount', 'defineAmount')])
}

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

def action_previous(self, cr, uid, ids, context=None):
    #your treatment to click  button previous 
    #...
    # update state to  step1
    self.write(cr, uid, ids, {'state': 'init',}, context=context)
    #return view
    return {
        'type': 'ir.actions.act_window',
        'res_model': 'staff_pay_push',
        'view_mode': 'form',
        'view_type': 'form',
        'res_id': this.id,
