Agora lá vai o código das Actions.

package br.com.sofistcar.beans;

import javax.persistence.EntityManager;

import org.jboss.seam.ScopeType;
import org.jboss.seam.annotations.Destroy;
import org.jboss.seam.annotations.In;
import org.jboss.seam.annotations.Name;
import org.jboss.seam.annotations.Scope;
import org.jboss.seam.faces.FacesMessages;

import br.com.sofistcar.model.User;

@Name("register")
@Scope(ScopeType.EVENT)
@Stateful
public class RegisterBean implements Register {

	@In
	private User currentUser;

	@In("#{entityManager}")
	EntityManager em;

	@In(create = true)
	private transient FacesMessages facesMessages;

	private String verifyPassword;

	public String getVerifyPassword() {
		return verifyPassword;
	}

	public void setVerifyPassword(String verifyPassword) {
		this.verifyPassword = verifyPassword;
	}

	@SuppressWarnings("rawtypes")
	public String doRegister() {
		if (!currentUser.getPassword().equals(verifyPassword)) {
			facesMessages.add("Passwords didn't match!");
			verifyPassword = null;
		return null;
		}
		
		List existing = em.createQuery("select u.username from User u" +
				" where u.username = :uname")
				.setParameter("uname", currentUser.getUsername())
				.getResultList();
		if (existing.size() != 0) {
			facesMessages.add("User exists!");
			return null;
		} else {
			em.persist(currentUser); // Grava no Banco de Dados
			facesMessages.add("Registration complete.");
			return "login";
		}
		}

	@Remove
	@Destroy
	public void destroy() {
	}

}

Se alguem puder ajudar eu agradeço.

Brother, coloque seu componente no diretório (src/hot) e ver se funciona.

Poste se funcionou ou não.

Abraço.

Romildo_Paiter 20 de jan. de 2011

Beleza Alberthy. Fiz o que vc me disse criei um novo package no src/hot, e coloquei o meu Beam e não funcionou, estou postando agora também o codigo do xhtml.

O mais estranho que esta o #{currentUser} esta criando o componente normalmente. não da erro.

Estou com esse mesmo problema. Conseguiu a solução.
Já estou atrasado a dias por cauda deste mesmo erro.

Romildo_Paiter 22 de jan. de 2011

E ai meu amigo, Alex, tudo bem.

Cara não sei o que tinha haver, mais o problema foi solucionado quando removi as anotações o @Stateful e o @Stateless das minhas Actions. Todas voltaram a funcionar
Se alguém puder dar uma explicada o porque as duas anotações causaram esse erro, ficaremos muito agradecidos.

Se do pessoal que
