Howdy folks!
After I finished migrating to the new velocity UI tags, I found out that my labels are not being looked up in the properties files anymore:
#tag(TextField "label='cadastro.userName'" "name='cadastro.userName'")
#tag(Password "label='cadastro.senha'" "name='cadastro.usuario.senha'")
#tag(Password "label='cadastro.confirmeSenha'" "name='confirmeSenha'")
#tag(Submit "value='continuar'")
