Question

CombinedResourceHandler是否可以忽略RichFaces JS文件？

当我让omnifaces结合所有JS文件时，包括RichFaces和Richfaces优化关闭

<context-param>
   <param-name>org.richfaces.resourceOptimization.enabled</param-name>
   <param-value>false</param-value>
</context-param>

我收到以下异常

    ...

但是，无论我在上下文参数org.omnifaces.COMBINED_RESOURCE_HANDLER_EXCLUDED_RESOURCES中输入什么，我都无法排除任何Richfaces资源。我尝试了诸如

之类的参数值

<param-value>richfaces:richfaces.js, richfaces:richfaces-queue.js, richfaces:richfaces-base-component.js</param-value>

您需要提供确切的资源标识符。那些不是有效的RichFaces资源标识符。你似乎已经猜到了。使用CombinedResourceHandler 不时，您可以通过查看生成的HTML输出轻松确定它们。给定/playground的上下文路径和*.xhtml的JSF映射，它看起来像这样：

<script type="text/javascript" src="/playground/javax.faces.resource/richfaces.js.xhtml"></script>
<script type="text/javascript" src="/playground/javax.faces.resource/richfaces-base-component.js.xhtml"></script>

/javax.faces.resource/ 之后没有 JSF映射的部分是资源名称。 ln请求参数中的部分是资源库（但是，正如您可能观察到的那样，RichFaces没有！）。资源标识符由library:name表示法表示，如果没有库，则表示name。

所以，这应该适合你：

<context-param>
    <param-name>org.omnifaces.COMBINED_RESOURCE_HANDLER_EXCLUDED_RESOURCES</param-name>
    <param-value>richfaces.js, richfaces-queue.js, richfaces-base-component.js</param-value>
</context-param>

请注意，不遵守资源库（并在其上预置另一层）确实是RichFaces的一个严重错误。另见其他What is the JSF resource library for and how should it be used?

对于具体问题

无关，我无法再使用RichFaces 4.3.6重现问题39。请随意在GitHub重新打开该问题，以及从完全空白项目开始重现问题所需的最少信息。
