从迁移到tomcat后，将JSF页面中的枚举值作为参数传递给bean方法失败 [英] Passing enum value as parameter to bean method from JSF pages fail after migrating to tomcat

问题描述

我最近将我的JSF应用程序（使用primefaces）从glassfish 3.1迁移到tomcat7服务器。以前通过 actionlistener 属性将enum值作为字符串传递给托管bean方法（不需要转换器将字符串转换为枚举）但现在它失败了 javax.el.MethodNotFoundException 。

I recently migrated my JSF app(using primefaces) from glassfish 3.1 to tomcat7 server. Previously passing the enum value as string to managed bean methods through actionlistener attribute worked(without the need for a converter to convert string to enum) but now it fails with javax.el.MethodNotFoundException.

JSF页面：

<h:form>
   <h:outputLabel value="Title"/><br/>
   <p:inputText value="#{lobController.current.title}"/>

   <p:commandButton action="#{lobController.create('CAR')}" value="Post"/>
</h:form>

管理bean方法

public void create(Type type) {
  ...
}

记录消息：

编辑

如果我更改托管bean方法，这将开始工作如下：

Edit

This starts working if I change the managed bean method as follow:

public void create(String type) {
     Type type = Type.valueOf(type);
     ...
}

在Tomcat 7.0.14上使用Primefaces 3.1和JSF 2.1.6

推荐答案

这是Tomcat的EL实现中的一个错误。我已经为您报告过了： issue 52970 。希望他们不像我以前的报告那样挑剔。

It's a bug in Tomcat's EL implementation. I've reported it for you: issue 52970. Hopefully they aren't as picky on this as on my previous reports.

在他们修复之前，最好的办法是删除 Glassfish 3的EL 2.2实现JAR文件在你的webapp的 / WEB-INF / lib 中，告诉Mojarra使用它来代替 web.xml ：

Until they get it fixed, your best bet is to drop a copy of Glassfish 3's EL 2.2 implementation JAR file in your webapp's /WEB-INF/lib and tell Mojarra to use it instead by the following entry in web.xml:

<context-param>     
    <param-name>com.sun.faces.expressionFactory</param-name>
    <param-value>com.sun.el.ExpressionFactoryImpl</param-value>   
</context-param>

更新：机票提到它是固定的，它将在7.0.27及之后。

Update: the ticket mentions that it's fixed and it will be in 7.0.27 and onwards.
