<a4j:support event="onchange" reRender="datatableId"
    ajaxSingle="true"
    actionListener="#{bean.appRed}" />

Answer 1

你应该把a4j:support它作为一个孩子rich:inputNumberSlider来让它工作。

同样出于性能和可用性的原因，我会考虑使用ignoreDupResponses和requestDelay属性（文档）：

<rich:inputNumberSlider id="slider"
    rendered="#{bean.showReductionForm}"
    value="#{bean.reduction}" 
    showArrows="true"
    width="220">

    <a4j:support event="onchange" reRender="datatableId"
        ajaxSingle="true"
        actionListener="#{bean.appRed}"
        ignoreDupResponses="true"
        requestDelay="300"/> 

</rich:inputNumberSlider>
