Question

我在一个EAR存档中有两个基于JSF的WAR项目，两个项目都将OmniFaces作为依赖项，它们都将被部署。部署时抛出此错误：

如果从一场战争中删除OmniFaces，部署工作正常。

Omnifaces 2.3，PrimeFaces 5.3，Payara 4.1.152

Answer 1

这是一个已知的问题，它是由CDI规范中的不清晰引起的。另见：

我必须承认@Eager未在多模块EAR中进行测试。这个NullPointerException是不幸的，它永远不会以这种方式使Web应用程序无法使用。最多只有OmniFaces CDI相关功能应该无法使用，但其余部分应该继续工作。

我已在此创建issue 290，我将根据issue 281针对当前可用的服务器重新测试多模块EAR中的所有CDI功能。

您最好的选择是编辑OmniFaces JAR并从其EagerBeansPhaseListener中删除/META-INF/faces-config.xml。只有视图范围bean的@Eager功能才会停止工作。

根据{{3}}

更新我修复了这个NPE。它已于今天issue 290提供。
