Boa noite,
Alguém poderia ajudar solucionar meu problema, toda vez que tento cadastrar um novo setor eu tenho esse problema, ele retorna null.
Erro: /cadastrosetor.xhtml @44,79 value="#{setorBean.setor.nome}": Target Unreachable, 'setor' returned null
Já tentei de diversas maneiras e mesmo assim não funciona.
cadastrosetor.xhtml<?xml version='1.0' encoding='UTF-8' ?>
