Virtual Field + Concat and find problems

Hi everyone, i have a table "clients" wich the model is "Client"... and in my table I have the fields "city" and "state" and others... Also I have the following virtualfield:

public $virtualFields = array(

    'local'=>"CONCAT(Client.city,' - ',Client.state)",

);

When i use a find "all" with the conditions 'Client.local'=>'Cascavel - PR' it works perfectly... but if I try to find with the conditions 'Client.local'=>array('Cascavel - PR','Toledo - PR'), cake gives me an error saying that the field Client.local doesnt exists...

Does anyone know where i am wrong??
