在获取数据表的过滤值后,我找不到更新组件的方法。我尝试了不同的方式:
测试1:我尝试使用Filter
事件的操作,但此事件在更改值之前完成,因此我无法使用新值进行计算
测试2:我尝试使用Filter
事件的监听器,但我在AjaxBehaviorEvent
测试3:我尝试在过滤值的setter中调用我的函数,计算已完成但未更新...所以我尝试使用RequestContext
的primefaces但它没有工作要么。
告诉我你是否有想法解锁一种方法,或提出新的解决方案=)
感谢您的帮助!
控制台返回,以显示事件的顺序。
>test 1
>test 2
>update other
>update filtered values
>test 3
HTML code:
<h:form id="form1">
<p:dataTable var="_remontee" value="#{ConsultationSaisieBean.m_valuesInDataGrid}"
filteredValue="#{ConsultationSaisieBean.m_filteredValues}" >
<p:ajax event="filter" listener="#{ConsultationSaisieBean.OnFilter}"
action="#{ConsultationSaisieBean.FilterAction}" update=":form2"/>
<p:columns value="#{ConsultationSaisieBean.m_columns}" var="column"
filterBy="#{_remontee[column.property]}" filterMatchMode="contains">
<f:facet name="header">
<h:outputText value="#{column.header}" />
</f:facet>
<h:outputText value="#{_remontee[column.property]}" />
</p:columns>
</p:dataTable>
</h:form>
<h:form id="form2">
<p:outputLabel id="other" value="#{ConsultationSaisieBean.m_serviceResult}" />
</h:form>
Java类:
/**
* function of the filter event's action
*/
public void FilterAction()
{
// TEST 1
System.out.println("test 1");
setM_consummableResult(Resultof(m_filteredValues))
}
/**
* function of event's listener
*/
public Map<String, Object> OnFilter(AjaxBehaviorEvent p_event)
{
// TEST 2
System.out.println("test 2");
setM_consummableResult(Resultof(m_filteredValues))
// return values wanted by the event
DataTable table = (DataTable) p_event.getSource();
Map<String, Object> filters = table.getFilters();
return filters;
}
/**
* Setter of the filtered values
*/
public void setM_filteredValues(List<Map<String, String>> p_filteredValues)
{
// UPDATE FILTERED VALUES
System.out.println("update filtered values");
super.setM_filteredValues(p_filteredValues);
// TEST 3
System.out.println("test 3");
setM_consummableResult(Resultof(m_filteredValues))
//Test to force update
RequestContext context = RequestContext.getCurrentInstance();
context.addCallbackParam("saved", true);
context.update("form2:other");
}
/**
* function to count the new result
*/
public void Resultof(List<Map<String, String>> p_filteredValues)
{
/* calcul the new values */
}
/**
* getter for update the other component
*/
public Double getM_consummableResult()
{
return m_consummableResult;
// UPDATE
System.out.println("update other");
}
public List<Map<String, String>> getM_filteredValues()
{
return m_filteredValues;
}
private void setM_consummableResult(Double m_consummableResult)
{
this.m_consummableResult = m_consummableResult;
}

我和你有同样的问题。我已经解决了使用remotecommand ...
<p:ajax event="filter" oncomplete="handleLoadStart();" update=":frm1:tablaFact :frm1:panelTotal"/>
...
<p:remoteCommand id="rcom" name="loadRemoteContent" process="@this" update="panelTotal, tablaFact" actionListener="#{listadoFacturasMB.filterListener2}"/>
...
<h:outputScript id="waypointScript" target="body">
function handleLoadStart() {
loadRemoteContent();
}
</h:outputScript>
...
public void filterListener2() {
try {
if (filterFacturaUtilList != null) {
//then filter is active, do something...
}
} catch (Exception e) {
JsfUtil.addErrorMessage(e, "Error: filterListener() " + e.getMessage());
}
}
filterFacturaUtilList是filteredValue
