<p：ajax>更新不工作primefaces 4.0到6.2迁移

Question

Primefaces 4.0到6.2迁移，那时Ajax更新事件无法正常工作

<p:selectOneMenu id="ddl_district"
 value="#{village_Entry.ddl_district}"
 valueChangeListener="#{village_Entry.ddl_district_changed}"
 styleClass="component-width">

     <f:selectItems value="#{village_Entry.ddl_district_options}"/>                                                                  

    <p:ajax event="change"
     Process="ddl_district"
     Update="ddl_taluka"/>

 </p:selectOneMenu>

 public void ddl_district_changed(ValueChangeEvent event) {
    ddl_district = event.getNewValue().toString();
    setDdl_taluka();      
}

Answer 1

您应该更新更准确：

<p:selectOneMenu id="ddl_district">                                                                    

<p:ajax event="change"
 Process="ddl_district"
 Update=":FORM_NAME:ddl_taluka"/>
