【问题描述】:
我有一个包含以下代码的 Web 应用程序:
<rich:dataScroller id="id1" for="tableX" execute="tableX" page="#{formBackingBean.navigationHelper.scrollerPage}" render="tableX-sc1 tableY" maxPages="5" scrollListener="#{aBean.handleScrollPage()}" fastControls="hide" />
我使用的是 Richfaces 4.2.0 final,在 JBoss 6 下(我使用 Mojarra 2.0.3 作为 JSF 实现)这工作正常。我在 JBoss EAP 6(即 Jboss 7)上安装了应用程序,但出现以下异常:

关于什么可能是错误的任何提示? 非常感谢!
【问题讨论】:
-
尝试删除那些不必要的括号。也许它扼杀了 JBoss 7 的 EL 实现。
