在Tomcat7.0.40中JSF2.1 OF1.4.1 PF3.5 我在docs中配置了FacesExceptionFilter和FullAjaxExceptionHandlerFactory - http://showcase.omnifaces.org/exceptionhandlers/FullAjaxExceptionHandler - http://showcase.omnifaces.org/filters/FacesExceptionFilter
我还添加了web.xml
<error-page>
<exception-type>java.lang.IndexOutOfBoundsException</exception-type>
<location>/errors/bug.xhtml</location>
</error-page>
登录后，我通过此导航规则进入主页
<navigation-rule>
<from-view-id>/stdPortal/index.xhtml</from-view-id>
<navigation-case>
<from-outcome>mainPortal</from-outcome>
<to-view-id>/stdPortal/stdPages/mainPortal.xhtml</to-view-id>
<redirect/>
</navigation-case>
</navigation-rule>
在mainPortal.xhtml中我有一个图表
<p:poll interval="60" update="graficoPresidio03Top" />
<p:barChart id="graficoPresidio03Top" value="#{mainPortalBean.graficoPresidio03Top}" legendPosition="ne"
style="width:1050px;height:300px" stacked="true" animate="true" xaxisAngle="45" seriesColors="ADFF2F, FFFF00, FFA500, FF4500"/>
</p:panel>
每次更新图表
@ManagedBean
@ViewScoped
public class MainPortalBean implements Serializable {
private static final long serialVersionUID = 5783190881181226264L;
@ManagedProperty( value = "#{user}" )
private UserBean userBean;
public void setUserBean( UserBean userBean ) {
this.userBean = userBean;
}
....
public CartesianChartModel getGraficoPresidio03Top() {
createGraficoPresidio03Top();
return graficoPresidio03Top;
}
我更改了for以创建索引超出范围的异常
private void createGraficoPresidio03() {
//here code with for modified
}
我在Tomcat LOG中获得当前响应

如何调整相关方向？看完FullAjaxExceptionHandler with datatable and lazydatamodel后 我没有日志，但是页面管理得当。
答案 0 :(得分：1)
停止在getter方法中执行业务逻辑。在生成HTML输出期间调用Getter方法。但是，如果由于响应缓冲区被刷新而已经将该输出的一部分发送到客户端，则存在无返回点的方法。您不能将alread-sent字节返回并呈现完全不同的页面（在本例中为错误页面）。客户端最终会出现半熟的页面，因为生成HTML输出已完全中止。
在生成HTML输出之前，您应该在动作/侦听器方法中执行业务逻辑。
更改滥用的getter方法
public CartesianChartModel getGraficoPresidio03Top() {
createGraficoPresidio03Top();
return graficoPresidio03Top;
}
public CartesianChartModel getGraficoPresidio03Top() {
return graficoPresidio03Top;
}
并将该操作方法调用为poll侦听器
<p:poll ... listener="#{mainPortalBean.createGraficoPresidio03Top}" />
无关，具有特定RuntimeException的错误页面是一种气味（这是一个错误！）。应该通过改变代码逻辑来修复RuntimeException，以免它被抛出。例如。通过if块预先检查苛刻条件。
