如何使用Ajax部分提交特定的jsf组件? [英] How to partial submit with ajax a specific jsf component?

问题描述

我有这样的东西:

<h:form id="form">
    <p:dialog id="profileDialogId">                 
        <p:panelGrid id="categoryFunctions" columns="2" >       
            <p:outputPanel id="profileFunctions" >
                <p:panelGrid  columns="1" >
                        <p:scrollPanel scrollMode="buttons" mode="native" >
                            <p:outputLabel for="functionList" value="Functions:" />
                                <p:selectManyCheckbox id="functionList" value="#{profileConf.selectedCategoryDto.selectedFunctions}" layout="pageDirection" >
                                    <f:selectItems  value="#{profileConf.selectedCategoryDto.functionList}" var="function" itemLabel="#{function.functionDesc}"  itemValue="#{function.functionCod}" />
                            </p:selectManyCheckbox>                                     
                        </p:scrollPanel>
                </p:panelGrid>
            </p:outputPanel>
        </p:panelGrid>                       
    </p:dialog>         
</h:form>           

我只想用ajax发送带有"functionsList" id的组件.

and I want to send with ajax only the component with "functionsList" id.

我已经尝试过

<f:ajax event="valueChange" execute=":form:functionList" listener="#{profileConf.functionsForCategory}" update=":form:functionList"/>

但是当我在functionsForCategory方法中放置一个断点时，selectedFunctions属性为null. 任何帮助将不胜感激.谢谢！

but when I put a breakpoint in functionsForCategory method selectedFunctions property is null. Any help will be appreciated. Thanks!

推荐答案

尝试一下

<p:ajax event="valueChange" listener="#{profileConf.functionsForCategory}" process="@this" update=":form:functionList"/>
