Hi,

In my custom wizard with different steps, I want to populate a m2m field defined on second step by selecting records with choice of first step... How can I do that in python code of action_choose ?

class account_change_lotnbr_wizard(osv.osv_memory):
_name='iota.change.lotnbr.wizard'

def act_cancel(self, cr, uid, ids, context=None):
    #self.unlink(cr, uid, ids, context)
    return {'type':'ir.actions.act_window_close' }

def act_destroy(self, *args):
    return {'type':'ir.actions.act_window_close' }

def action_choose(self,cr,uid,ids,context=None):
    if not context:
        context={}

    this = self.browse(cr, uid, ids)[0]
    wizard=self.browse(cr,uid,ids[0],context=context)

    # Contrôle pour recherche
    if not wizard.date_invoice:
        raise osv.except_osv(_('Error !'), _('No date !'))
    if not wizard.product_id:
        raise osv.except_osv(_('Error !'), _('No product !'))
    if not wizard.new_lot_nbr:
        raise osv.except_osv(_('Error !'), _('No new lot number !'))

    # Définition des objets
    invoice_obj = self.pool.get('account.invoice')

    # Recherche des factures à réaffecter
    inv_select_ids = []
    inv_ids = invoice_obj.search(cr, uid, [('date_invoice', '=', wizard.date_invoice), ('type', '=', 'out_invoice')])
    invs = invoice_obj.browse(cr, uid, inv_ids, context)
    for inv in invs:
        inv_select = False
        for line in inv.invoice_line:
            if line.product_id.id == wizard.product_id.id:
                inv_select = True
                break
        if inv_select:
            inv_select_ids.append(inv.id)

    # Mise à jour du wizard pour passer à l'étape suivante
    self.write(cr, uid, ids, {'state':'get'}, {'invoice_ids':inv_select_ids})

    return {
        'type': 'ir.actions.act_window',
        'res_model': 'iota.change.lotnbr.wizard',
        'view_mode': 'form',
        'view_type': 'form',
        'res_id': this.id,
        'views': [(False, 'form')],
        'target': 'new',
        }

def action_confirm(self,cr,uid,ids,context=None):
    if not context:
        context={}

    #this = self.browse(cr, uid, ids)[0]
    wizard=self.browse(cr,uid,ids[0],context=context)

    # Contrôle pour recherche
    if not wizard.invoice_ids:
        raise osv.except_osv(_('Error !'), _('No invoice !'))

    return {'type':'ir.actions.act_window_close' }

_columns = {
           'date_invoice': fields.date('Invoice Date'),
           'product_id': fields.many2one('product.product', 'Product'),
           'new_lot_nbr': fields.char('Lot number', size=15),
           'invoice_ids':fields.many2many('account.invoice','wiz_change_lotnbr','wiz_id','invoice_id','Invoices'),
           'state': fields.selection( ( ('choose','choose'),
                                        ('get','get'),
                                   ) ),
           }

_defaults = {
    'date_invoice': fields.date.context_today,
    'state': lambda *a: 'choose',
}

account_change_lotnbr_wizard()

E.g : In the first step, I give a date and product_id when I go to step 2, i want to obtain a list of invoices with a date and which have one line of product in invoice_ids field
