Primefaces import enum all 选项不适用于 JSF PROJECT_STAGE 设置为 Production

问题描述 投票：0回答：1

我有一个 Java EE Web 项目，我在其中使用 Primefaces 作为 UI 组件。我正在使用 Primefaces 提供的带有全后缀的导入枚举功能。当我的 JSF PROJECT_STAGE 设置为 Development 时，一切正常。当我将其更改为生产时，出现以下异常

我的网页分数如下

            <p:importEnum type="org.myEnum" var="opt" allSuffix="ALL_OPTS"/>
            <p:outputPanel style="display:flex;">
                <p:selectOneRadio id="one-radio"  
                                  value="#{myView.option}" 
                                  >
                    <f:selectItems value="#{opt.ALL_OPTS}" var="ui_opt"
                                   itemLabel="#{ui_opt.displayName}"
                                   itemValue="#{ui_opt}" itemLabelEscaped="false"/>
                </p:selectOneRadio>
            </p:outputPanel>

我认为这可能是一个错误，但是当我尝试在一个独立的示例项目中使用这个 Web 部分并将项目阶段设置为生产的一个页面时，它可以工作。我现在很困惑。

以下是项目详情

Import Enum 有一个定义“allSuffix”的选项。我将其定义为自定义字符串。当我删除它并使用默认的 ALL_VALUES 时，生产 PROJECT_STAGE 中一切正常。

我不知道为什么，但它有效。我需要挖掘更多才能理解。

下面是抛出异常之前的片段 - 

            <p:importEnum type="org.myEnum" var="opt" allSuffix="ALL_OPTS"/>
            <p:outputPanel style="display:flex;">
                <p:selectOneRadio id="one-radio"  
                                  value="#{myView.option}" 
                                  >
                    <f:selectItems value="#{opt.ALL_OPTS}" var="ui_opt"
                                   itemLabel="#{ui_opt.displayName}"
                                   itemValue="#{ui_opt}" itemLabelEscaped="false"/>
                </p:selectOneRadio>
            </p:outputPanel>

以下是工作片段--

            <p:importEnum type="org.myEnum" var="opt"/>
            <p:outputPanel style="display:flex;">
                <p:selectOneRadio id="one-radio"  
                                  value="#{myView.option}" 
                                  >
                    <f:selectItems value="#{opt.ALL_VALUES}" var="ui_opt"
                                   itemLabel="#{ui_opt.displayName}"
                                   itemValue="#{ui_opt}" itemLabelEscaped="false"/>
                </p:selectOneRadio>
            </p:outputPanel>

**注意，

allSuffix
未定义，内置名称
ALL_VALUES
用于引用
f:selectItems
中的所有枚举值。 **
