带有Primefaces图表的CDI无法正确呈现

时间：2014-05-29 16:13:08

标签： java jsf primefaces cdi

我有4个Primefaces条形图，有时会呈现，有时不会。在其中一个中，我注入一个http用户会话属性并使用它来呈现图表（想法是仅显示与（登录的）用户部门对应的数据）。

有4个会话bean我正在使用javax.enterprise.context.RequestScoped。有时，Glassfish会按预期破坏实例，但有时不会。

根据以下异常，我该如何解决？

提前致谢。

下面的xhtml显示了4个条形图中只有2个的主要代码：

<p:tab title="Horas de Treinamento (por Funci)" closable="true" >
 <p:barChart id="horasBars" value="#{chartHorasFunci.modelHoras}" 
    legendPosition="ne" 
    orientation="horizontal"
    seriesColors="AA5555, 00438F"
    xaxisLabel="Horas" yaxisLabel="Funcis"
    title="34 Horas de Treinamento (Orçado/Realizado) por Funci" 
    >
</p:barChart>
</p:tab>

<p:tab title="Horas de Treinamento (por Escritório)" closable="true" titletip="Este subitem impacta no ATB.">
<p:barChart id="horassBarsEsc" value="#{chartHorasEsc.modelHorasEsc}" 
    legendPosition="ne" 
    orientation="vertical"
    seriesColors="AA5555, 00438F"
    xaxisLabel="Prefixo" yaxisLabel="Quantidade"
    title="Horas de Treinamento (Orçado/Realizado) por Prefixo" 
    >
</p:barChart>

下面的会话bean仅显示4会话bean中的1个的主要代码：

@Named(value = "chartHorasFunci")
@RequestScoped
public class ChartHorasFunci implements Serializable {

private final BeanLogin sessionPrefDep = new BeanLogin();
private final String sessionAttribute = FacesContext.getCurrentInstance().getExternalContext().getSessionMap().get("xPrefDep").toString();

public ChartHorasFunci() {
}

@EJB
private CapacitacaoFacade cf;

@EJB
private PrefDepsFacade pf;

private CartesianChartModel modelHoras;

public CartesianChartModel getModelHoras() {
    return modelHoras;
}

public void setModelHoras(CartesianChartModel modelHoras) {
    this.modelHoras = modelHoras;
}

private void HorasChart() {
    List<Capacitacao> orcList = cf.findByPrefDep();
    List<PrefDeps> prefDepsList = pf.findAll();

    sessionPrefDep.setxPrefDep(sessionAttribute);
    System.out.print("from init:" + sessionPrefDep.toString());

    modelHoras = new CartesianChartModel();

    ChartSeries orcHorasSeries = new ChartSeries("Orçado");
    ChartSeries rlzHorasSeries = new ChartSeries("Realizado");

    for (PrefDeps p : prefDepsList) {
        Integer metaHoras = 0;
        Integer rlzHoras = 0;

        Integer x = 0;
        Integer y = 0;

        for (Capacitacao r : p.getCapacitacaoCollection()) {
            if (r.getIdDtRef().getId().intValue() == 1) {
                if (r.getIndicativo().equals("")) {
                    x++;
                }

                if (r.getAtgHoras().equals("Sim")) {
                    y++;
                }
                metaHoras = x.intValue();
                rlzHoras = y.intValue();

            }
        }
    }

    for (Capacitacao o : orcList) {
        if (o.getPrefDep().getPrefDep().toString() == null ? sessionPrefDep.getxPrefDep().toString() == null : o.getPrefDep().getPrefDep().toString().equals(sessionPrefDep.getxPrefDep().toString())) {
            orcHorasSeries.set(o.getFunci(), o.getMetaHoras().getValor());
            rlzHorasSeries.set(o.getFunci(), o.getRlzHoras().floatValue());
        }
    }
    modelHoras.addSeries(orcHorasSeries);
    modelHoras.addSeries(rlzHorasSeries);
}

@PostConstruct
private void initialize() {
    HorasChart();
}

@PreDestroy
public void cleanUp() {
    System.out.println("Destoy the instances here!!"); // <-- sometimes destroys, sometimes not!
}

}

@PostConstruct触发的应用程序代码中似乎存在问题。这是stacktrace的有趣部分：

看起来你生成的输出比流可以处理的更多，所以它毕竟不是CDI问题。
