how can I list items on one2many without have to click on add item? I have two classes to build two tables:

class tabela_recintos(osv.osv):

_name = 'tabela.recintos'

_columns = {

'recinto_ids': fields.one2many('tabela.lista','id_wizard','teste')
}

tabela_recintos()

class tabela_lista(osv.osv):

_name = 'tabela.lista'

_columns = {

        'id_wizard':fields.many2one('tabela.recintos','id_wizard'),
       'cod': fields.char('Código', size=20, required='True'),
       'nome': fields.char('Designação', size=60, required='True')
        }

I click on a menu on the left and pop's up a wizard, this wizard ll list the items, but I dont know what can I do more. it only shows a field and the button add item...

my xml is this

<record id="carrega_form" model="ir.ui.view">
    <field name="name">carrega.form</field>
    <field name="model">tabela.recintos</field>
    <field name="arch" type="xml">
        <form string="carrega" version="7.0">

            <group string="carrrega" col="1">

        <field name="recinto_ids"/>

            </group>

            <footer>
               <button name='name' type='object' string='Criar novo Recinto' class="oe_highlight"/>
                ou
                <button string="Cancelar" class="oe_link" special="cancel"/>
            </footer>
        </form>
    </field>
</record>

<record id="gs_carrega_act" model="ir.actions.act_window">
    <field name="name">Carregar os Recintos</field>
    <field name="type">ir.actions.act_window</field>
    <field name="res_model">tabela.recintos</field>
    <field name="view_type">form</field>
    <field name="view_mode">form</field>
    <field name="target">new</field>
</record>

<menuitem
    name="Carrega Recinto teste"
    parent="gs_menuLotacoes"
    action="gs_carrega_act"
    id="gs_carrega"
    sequence="0"/>
