Re: [rules-users] Evaluating an attribute of an object in Arraylist

Thanks for your answer but I forgot to say that I want to use the gloabal variable *locacoes*. *locacoes *is an ArrayList containing a list of umLocacaoImediata. How do I iterate over *locacoes* and discover if there is an object with the same name of the variable $motorista??? Thanks!
