我将 PrimeFaces 5.2 与 Mojarra 2.2.8 和 JSF 2.2.10 一起使用.
I'm using PrimeFaces 5.2 with Mojarra 2.2.8 and JSF 2.2.10.
推荐答案
当 runtime 类路径因重复的不同版本库而变脏时，可能会发生这种情况.然后在类加载和资源解析过程中会发生冲突.
That can happen when the runtime classpath is dirty of duplicate different versioned libraries. Conflicts would then occur during class loading and resource resolving.
确保您只使用一个版本的库.这不仅适用于 PrimeFaces，也适用于 Mojarra.同时拥有 2.2.8 和 2.2.10 肯定是不对的.
Make sure that you're using only one version of a library. This not only applies to PrimeFaces, but also to Mojarra. Having both 2.2.8 and 2.2.10 is definitely not right.
