Utilizando listShuttle com Seam

Olá!

Estou tendo dificuldades em utilizar o componente listShuttle com o Seam.

Eis o trecho da página xhtml

<s:decorate id="usuariosField" template="/layout/display.xhtml">
				<ui:define name="label">#{messages['areaPesquisa.usuarios.label']}</ui:define>
				<rich:listShuttle id="usuarios"  sourceCaptionLabel="#{messages['areaPesquisa.usuarios.tabela.fonte.label']}"
								  var="_usuario" targetRequired="true" targetCaptionLabel="#{messages['areaPesquisa.usuarios.tabela.destino.label']}"
								  targetValue="#{areaPesquisa.usuarioList}"
								  sourceValue="#{administrarAreaPesquisaAction.listaUsuarios}"
								  converter="#{usuarioConverter}">
					<rich:column>
						<h:outputText value="#{_usuario.nome}" />
					</rich:column>				  
				</rich:listShuttle>
			</s:decorate>

O problema esta relacionado a classe que faz a conversão do objeto em string e vice-versa.

Esse é o código do converter

@Name("usuarioConverter")
@Converter
@BypassInterceptors
public class UsuarioConverter implements javax.faces.convert.Converter {

	@Logger
	private Log log;
	
	@In
	private EntityManager entityManager;
	
	@Override
	public Object getAsObject(FacesContext arg0, UIComponent arg1, String arg2) {
		Usuario usuario = null;
		long id = Long.parseLong(arg2);
		
		if (entityManager != null) {
			usuario = (Usuario) entityManager.createQuery("select u from Usuario u where u.id = ?").setParameter(1, id).getSingleResult();
		} else {
			log.info("TA VINDO NULO!!");
		}
		
		return usuario;
	}

	@Override
	public String getAsString(FacesContext arg0, UIComponent arg1, Object arg2) {
		Usuario u = (Usuario) arg2;
		return Long.toString(u.getId());
	}

}

Inicialmente eu não utilizava a anotação @BypassInterceptors mas o JBoss se quer subia. Sem esta anotação é exibida a seguinte exceção.

16:05:44,421 WARN  [HDScanner] Failed to process changes
org.jboss.deployers.client.spi.IncompleteDeploymentException: Summary of incomplete deployments (SEE PREVIOUS ERRORS FOR DETAILS):

No entanto, quando eu adiciono a anotação passo ter problemas com o DI do entityManager.
Sem o entityManager não tenho como recuperar o objeto.

Bom, como não tenho muito conhecimento em JSF e Seam, gostaria de saber se existe outra maneira de fazer a recuperação do objeto ou como conseguir uma instância do EntityManager.

Obrigado pela ajuda!
