jsf-2 - 警告 : Unsupported component-family/renderer-type: org.omnifaces.component.script/javax.faces.Button

Question

我定义了以下形式:

<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>

当我加载页面时，我会反复向 Stdout 发送此错误:

我在这里做错了什么？

Answer 1

你没有做错什么。 CommandScript从 UICommand 继承了 javax.faces.Button 的渲染器类型它继承自的类，而它应该 actually当 CommandScript 自行渲染时已设置为 null。 MyFaces 只是警告关联的渲染器实现无法解析。此问题已在 OmniFaces 1.5 中修复。
