Question

我最近将我的JSF版本从2.2更改为2.3，从而将javax.faces.PROJECT_STAGE的默认值从Development修改为Production。这导致了意外的行为-f:param的值不再包含在ExternalContext requestParameterMap中。

用例很简单-我希望仅在发生特定的用户操作时才执行验证。例如：

<h:commandLink value="Save changes">
    <f:param name="performValidation" value="true"/>
    <f:ajax listener="#{bean.save()}"
            execute="#{cc.clientId}:content"
            render="#{cc.clientId}:content" 
            onevent="showLoader"/>
</h:commandLink>

这会执行一些输入，包括带有验证器的隐藏输入：

<h:inputText style="display:none;" value="abc" validator="#{bean.validate}"/>

验证器代码如下：

public void validate(FacesContext context, UIComponent component, Object value) {
    if (!"true".equals(context.getExternalContext().getRequestParameterMap().get("performValidation"))) {
        return;
    }

    ... Prepare the List<FacesMessage> and throw it in ValidatorException if not empty ...
}

消息显示在单个h:messages组件中，该组件放置在带有rendered="#{facesContext.validationFailed}"的渲染容器中。

将javax.faces.PROJECT_STAGE中的web.xml设置为Development可解决此问题。不过，我很想了解-为什么Production设置会破坏此代码？
