LazyInicializationException

Pessoal, estou recebendo essa exceção ao tentar usar a lista de e-mails do usuário na lista abaixo:

Obs.: Com fetch EAGER, funciona corretamente, mas são várias listas dentro do objeto.

<p:dataTable value="#{loginBean.responsavel.emails}" var="email" id="tabelaEmails" emptyMessage="Nenhum email">
    <p:column>
        <h:outputText value="#{email.endereco}" />
    </p:column>                        
</p:dataTable>
