Dialog Framework Primefaces - n�o consigo ter resposta de lista

20/04/2020

Ol�, pessoal.
Estou a precisar de utilizar o Dialog Framework do Primefaces para ter uma lista e em seguida selecionar um artigo. Vi no Show case do Primefaces o exemplo e tentei fazer, mas n�o consigo ter resposta da sele��o. Faz a lista mas n�o obtenho nenhuma resposta. Algu�m me consegue ajudar? Aqui tem o meu c�digo:
Esta � o meu faces-config:
<?xml version='1.0' encoding='UTF-8'?>
<faces-config version="2.2"
xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-facesconfig_2_2.xsd">
<application>
<action-listener>
org.primefaces.application.DialogActionListener
</action-listener>
<navigation-handler>
org.primefaces.application.DialogNavigationHandler
</navigation-handler>
<view-handler>
org.primefaces.application.DialogViewHandler
</view-handler>
</application>
</faces-config>

        return cars;
    }

        this.service = service;
    }
