e quando eu click em:

ele me aponta a variavel que está recebendo o resultado:

balancoLinkUmjAux = ocorrenciaLinkFacade.buscarGraficoUmjLink(unidadeBusca);

e essa variável está nesse método:

        if ("todas".equals(unidadeBusca)) {
            Long aux = 0L;
            balancoLinks = ocorrenciaLinkFacade.buscarOcorrenciaLinks(unidadeBusca, dataInicial, dataFinal);

                Integer value2 = ocorrenciaLinkFacade.contaFechouLink(b.getUnidade(), dataInicial, dataFinal);
//            Integer fechou = ocorrenciaLinkFacade.contaFechouLink(b.getUnidade()).size();
                b.setCfalha(value.longValue());
                b.setFinalizado(value2.longValue());
//            b.setFinalizado(fechou.longValue());
                if (b.getTotal() > aux) {

                } else {

                }

            }
            gerarGrafico();
            graficoPizza();
        } else {

            graficoLinhaUMJ();
        }
    }

alguém sabe o porque disso, o que está errado? agradeço muito.
