Fala galera buenas?
Então… estou com o seguinte problema o f:setPropertyActionListener não esta passando o OBJETO :@ o que eu quero é simplesmente passar um objeto e excluir a bendita linha da tabela.
ERRO: java.lang.IllegalArgumentException: Object: null is not a known entity type.
QUEM SERÁ MEU HEROI?
