Hello guys, i'm trying to seek an object in an ArrayList, but I don't know how I do it. I'm inserting this list as a global variable into drools, but I'd like to check if there is an ojbect in this list with a specific name. Could Anybody help me? The code is below: global java.util.List locacoes rule "Cliente pode alugar" when $motorista : umMotorista() // $list : ArrayList() from collect( umLocacaoImediata( cliente == $motorista(nome) ) ) then $motorista.setPodeAlugar(false); System.out.println($motorista.getNome() + " já possui uma alocacao"); update($motorista); end I'm trying to compare the attribute cliente from umLocacaoImediata with the attribute nome from motorista. How do I do it? If anybody can help me with the right way to do it, answer this mail, please.
