I can’t see the validation errors.

this is the rules.

return array(

        array('cod_casa,preco,inicio, fim,defaccao', 'required'),


        array('ano, n_semana, cod_casa, preco', 'numerical', 'integerOnly' =&gt; true),


        array('nm_mes, inicio, fim, reservar', 'length', 'max' =&gt; 50),


        array('livre, promo, paga,defaccao', 'safe'),


        // The following rule is used by search().


        // Please remove those attributes that should not be searched.


        array('id, ano, nm_mes, n_semana, cod_casa, inicio, fim, preco, livre, reservar, promo, paga,defaccao', 'safe', 'on' =&gt; 'search'),


    );
