我应该在 RichFaces 4.0 中将 a4j:htmlCommandLink 替换为什么？

Question

我正在使用 JSF 2.1_29，在将 RichFaces 3.3.3 升级到 4.5.2.Final 之后，我遇到了 a4j:htmlCommandLink 标签的问题。它只是没有在 RichFaces 标记库中定义。我得到了以下异常：

javax.servlet.ServletException: bonusList.jspx @257,109 <a4j:htmlCommandLink> Tag Library supports namespace: http://richfaces.org/a4j, but no tag was defined for name: htmlCommandLink

顺便说一句，我已经阅读了 RichFaces a4j-components migration guide 并没有说明在 RichFaces 4.x.x 中替换该组件的任何内容。那么，我应该将该组件替换为什么？

您可以使用a4j:commandLink。见RichFaces documentation。

其他替代方案：h:commandLink、h:outputLink 和 h:link。见JSF documentation。
