隐式表达语言对象"component"在jsf 2.2.6中不起作用 [英] Implicit expression language object "component" not working in jsf 2.2.6

问题描述

我正在将jsf 2.0应用程序迁移到jsf 2.2.6.

I'm migrating a jsf 2.0 application to jsf 2.2.6. There is a extensive use of implicit EL object component as styleClass="#{component.valid?'':'err'}".

在jsf 2.2.6(jsf-impl-2.2.6-jbossorg-4.jar)中，有效值无法识别，并抛出"ServletException:类'javax.faces.component.html.xxx'不具有该属性有效".

In jsf 2.2.6 (jsf-impl-2.2.6-jbossorg-4.jar) valid is not recognized, throwing "ServletException: The class 'javax.faces.component.html.xxx' does not have the property 'valid".

此功能是否在jsf 2.x.x中被弃用?

Is this functionality deprecated in jsf 2.x.x?

可以与JBoss EL相关吗?

Can be related to JBoss EL?

推荐答案

最终找到了异常原因.问题是我在包含"component.valid"的代码中有一个注释.删除评论即可解决问题.

Finally found the reason of the exception. The problem was that I had a comment in the code containing "component.valid". Removing the comment resolves the problem.

<!-- styleClass="#{component.valid ? '': 'err' }" -->

这很棘手.关于代码行，尚不清楚.

It's tricky. The exception was not clear about the line of code.
