Question

我在index.xhtml中显示了三个图表，表示来自数据表的数据。

在这样的数据表（在List.xhtml中）中插入一个寄存器之后，所有三个图表也应该立即更新，但只有2个按预期更新 - 顺便说一下，这两个barCharts。

pieChart已更新，但不会像其他两个barCharts一样立即更新，只会在重新启动Glassfish后或插入很长时间后更新。

为什么在数据表中插入新寄存器后，pieChart没有立即更新？我该如何解决这个问题？

遵循图表bean的代码摘录：

import br.com.bb.upb.diage.treinamentos.facades.UorPosFacade;
import java.io.Serializable;
import javax.annotation.PostConstruct;
import javax.annotation.PreDestroy;
import javax.ejb.EJB;
import javax.enterprise.context.RequestScoped;
import javax.inject.Named;
import org.primefaces.model.chart.PieChartModel;

@Named(value = "chartBeanUPB")
@RequestScoped
public class ChartBeanUPB implements Serializable {

    @EJB
    private UorPosFacade uf;

    private PieChartModel modelChartBeanUPB;
    //get and set ommited

    private void TreinamentoUPBChart() {

        modelChartBeanUPB = new PieChartModel();

        //get data from database

        modelChartBeanUPB.set("Orçado", orcData);
        modelChartBeanUPB.set("Realizado", rlzData);
        //another settings for the graphic
    }

    @PostConstruct
    public void initialize() {
        TreinamentoUPBChart();
    }

    @PreDestroy
    public void cleanUp() {
    }

}
