在嵌套控件内更新PrimeFaces DataTable



我是JSF和PrimeFaces的新手。我正在尝试在嵌套元素中更新数据。到目前为止,我尝试过的一切都打破了页面或失败。这是标记:

我试图通过命令按钮从第二个布局单元中更新第三个布局单元中的数据表。

我尝试使用命令按钮的更新属性,但似乎要做的就是打破向导,不允许我输入它的标签。

我还尝试从bean更新它:

public void addAnother(Flight f){
    flightMB.addFlightToCreate(f);
    flightMB.setFlight(new Flight());
    RequestContext reqCtx = RequestContext.getCurrentInstance();
    // reqCtx.update("form2:submissionUnit");
    reqCtx.update("form2:layoutUnit");
}

此时的任何帮助将不胜感激。

,而不是更新整个p:layoutUnit。您可以更新数据表,也可以围绕它放置h:panelGroup并进行更新。

@xhtml:

<h:form id="form1">
<p:layoutUnit id='submissionUnit'>
<h:panelGroup id="tablePG">
<p:dataTable id='submissionTable'>
...
</p:dataTable>
</h:panelGroup>
</p:layoutUnit>
</h:form>

@managedBean:

RequestContext.getCurrentInstance().update("form1:tablePG");

,请注意,在使用RequestContextManagedBean更新组件时,您无需在组件ID的开始时提供:
