警告：不支持的组件家庭/渲染器型：org.omnifaces.component.script/javax.faces.Button

Question

我有以下形式定义：

<ui:define name="body"> 
    <h:form 
     id="posForm" 
     styleClass="well span12"> 
.... 
     <o:commandScript 
      id="createTransactionCommandScript" 
      rendered="#{multiTenantBean.currentAccount.stripePublishableKey != null}" 
      name="createTransaction" 
      actionListener="#{posMB.createTransaction}" 
      execute="@form" 
      render="@form" /> 
    </h:form> 
</ui:define> 

当我打开我的网页，我得到这个错误吐到Stdout反复：

我在做什么错在这里？

Answer 1

你没有做错什么。 CommandScript继承自UICommand类的javax.faces.Button的渲染器类型，它从其扩展而来，而actually已被设置为null，因为CommandScript自己渲染。 MyFaces只是警告相关的渲染器实现无法解析。这在OmniFaces 1.5中得到了解决。
