使用 panelGrid 时出现 xhtml 错误-解网

问：

我在 xhtml 中收到错误。. 代码是：

<h:form>
  <h:panelGrid columns="2">
    <h:outputLabel value="Name:" />
    <h:inputText value="#{newAuctionWizard.auction.name}" />

    <h:outputLabel value="Description:" />
    <h:inputTextarea value="#{newAuctionWizard.auction.description}" />

    <p:outputLabel for="category" value="Categories from which to pick:" />
    <p:selectOneRadio id="category" value="#{newAuctionWizard.auction.category}"  
     layout="grid" columns="3">
      <f:selectItems value="#{newAuctionWizard.auction.categories}" 
       var="c" itemLabel="#{category}" itemValue="#{category}"/>
    </p:selectOneRadio>

    <h:commandButton value="Cancel" action="#{newAuctionWizard.cancel()}" />    
    <h:commandButton value="Details" action="newAuctionDetails" />  
  </h:panelGrid>

包含此部分后出现错误：

 <p:outputLabel for="category" value="Categories from which to pick:" />
   <p:selectOneRadio id="category" value="#{newAuctionWizard.auction.category}"  
   layout="grid" columns="3">
     <f:selectItems value="#{newAuctionWizard.auction.categories}" var="c"
      itemLabel="#{category}" itemValue="#{category}"/>
   </p:selectOneRadio>

我已经为 p 元素添加了命名空间，但仍然无法将其包含在 panelGrid 中。有人可以告诉我我做错了什么吗？错误是：

做。。它现在说：新的缺失/不满意的依赖项：service jboss.deployment.unit。auctioner-0.0.1-SNAPSHOT.war”。WeldBootstrapService（缺失）依赖项：[service jboss.deployment.unit。auctioner-0.0.1-SNAPSHOT.war“.组件。AuctionManagerImpl.WeldInterceptorBindingsService，服务 jboss.deployment.unit。auctioner-0.0.1-SNAPSHOT.war“.组件。NewAuctionWizard.WeldInstantiator，服务 jboss.deployment.unit。auctioner-0.0.1-SNAPSHOT.war“.组件。UserManagerImpl.WeldInstantiator，服务

此日志与 selectOneRadio 无关

你必须把 itemLabel=“#{c}” itemValue=“#{c}”，并确保 auction.category 是一个字符串

是的，对不起..它说： SNAPSHOT.war#auctionPersistenceUnit\“： javax.persistence.PersistenceException： [PersistenceUnit： auctionPersistenceUnit] 无法构建 Hibernate SessionFactory 原因： javax.persistence.PersistenceException： [PersistenceUnit： auctionPersistenceUnit] 无法构建 Hibernate SessionFactory 原因： org.hibernate.MappingException：无法确定类型： java.util.List，在表： AUCTION，对于列： [org.hibernate.mapping.Column（categories）]”}}

上一个：在符合 XHTML 1.1 标准的同时使用 AngularJS 引用表单的正确方法？

下一个：JavaScript 仅验证第一个字段
