我第一次点击" Visa lista"时,图表不会显示任何结果。按钮。 " teamList"将在第一次正确更新。在第一次尝试退出函数时,将调用createChart()并具有正确的信息。该函数将返回CartesianChartModel。
如果我退出页面或重新加载页面,图表将是正确的。每次点击" Visa lista"。
时,它也会正确更新编辑:按下按钮后,页面也将停止处理咆哮信息。这也将在页面刷新后恢复工作。

根据要求。添加bean和图表。

答案 0 :(得分:0)
我相信serviceTeam
也是@ManagedBean
。您不能使用@ManagedBean
作为函数的参数。 serviceTeam
所需的内容是teamList
,因此请更改createChart
函数,如下所示:
public CartesianChartModel createChart(List<Team> teamList) {
...
}
然后你的<p:barChart>
应该是这样的:
<p:barChart id="chart" value="#{teamChart.createChart(serviceTeam.teamList)}" legendPosition="ne"
title="Lagresultat" animate="true" zoom="true" min="0" max="6000" xaxisLabel="År och vecka" style="height:300px"/>
答案 1 :(得分:0)
如果你试图在没有真实信息的情况下渲染图表,似乎有些东西会在Primefaces中以非法状态结束。
在初始化之前删除渲染后,它会起作用。缺少的是停止渲染空。
rendered="#{not empty serviceTeam.teamLists}"
这是我改变的barChart的样子。
<p:barChart id="chart" value="#{teamChart.CreateChart(serviceTeam.teamLists)}"
rendered="#{not empty serviceTeam.teamLists}" legendPosition="ne"
title="Lagresultat" animate="true" zoom="true" min="0" max="6000" xaxisLabel="År och vecka" style="height:300px"/>
