Omnifaces FullAjaxExceptionHandler + <error-page> 生成 ContextNotActiveException

Question

我在访问应用程序的任何视图（xhtml）时遇到问题。javax.enterprise.context.ContextNotActiveException：如果我设置了错误页面标记，那么在访问任何视图时都会发生以下异常。应用程序工作正常，但在访问任何视图时都会发生异常。如果我删除错误页面标记的配置，则不会发生异常。我使用的是primefaces 4+WAS 8.5.5.1（MyFaces+OpenWebBeans）。我将感谢的任何帮助

编辑：我注意到只有在设置标记错误代码时才会出现错误。

<error-page>
    <error-code>500</error-code>
    <location>/paginas/erro/erro500.xhtml</location>
</error-page>

如果我只设置了异常类型标记，则不会出现问题。

<error-page>
    <exception-type>java.lang.RuntimeException</exception-type>
    <location>/paginas/erro/erro500.xhtml</location>
</error-page>

*编辑2*如果我删除404错误页面定义，则不会引发异常

Answer 1

我们遇到了同样的问题，现在这是WAS v8.5.5.x 中的一个已知错误

我们打开了IBM的PMR，刚刚收到他们的修复：这是APAR PI26908

我不知道它是否会包含在WAS v8.5.5.4中（我们现在使用WAS V88.5.5.3）

还有这个修复程序，我们需要在web容器上设置com.ibm.ws.webcontainer.deferreServletRequestListenerDestroyOnError=true

您应该联系然后接收此iFix

Answer 2

也许为时已晚，但更多信息：

• APAR：http://www-01.ibm.com/support/docview.wss?uid=swg1PI26908
• "修复"：http://www-01.ibm.com/support/knowledgecenter/api/content/nl/hu/SS7K4U_8.5.5/com.ibm.websphere.nd.doc/ae/rweb_custom_props.html#com.ibm.ws.webcontainer.deferServletRequestListenerDestroyOnError

短：应向server.xml添加一个自定义属性，其中包含以下内容：

<webContainer deferServletRequestListenerDestroyOnError="true" />

属性描述："如果此自定义属性设置为true，则web容器使CDI能够在自定义错误页面上正常工作"（属性默认为false）
