Custom renderer for PrimeFaces component works fine in Tomcat, but not in Websphere

Solution
Custom renderers which needs to override renderers of 3rd party component libraries needs to be registered in webapp's own `faces-config.xml`, not in a `faces-config.xml` which is packed in another JAR in `/WEB-INF/lib` as well. The loading order of JAR files is unspecified, so it may happen that the custom renderer is loaded and registered before the one of the 3rd party component library which you'd like to override, exactly like as you faced.
Problem
I'm using MyFaces 2.1.9 and PrimeFaces 3.5. I've implemented a custom renderer for `<p:inputText>`. This works fine at home with Tomcat. But this does not work at work with Websphere. I've placed breakpoints in the custom renderer class, but they are never hit. I see nothing in my logs as well. However, when I register the very same custom renderer on standard JSF `<h:inputText>`, then it works fine. I've registered it as follows in `faces-config.xml`: ``` <render-kit> <renderer> <component-family>org.primefaces.component</component-family> <renderer-type>org.primefaces.component.InputTextRenderer</renderer-type> <renderer-class>xxx.xxx.xxx.MyInputRenderer</renderer-class> </renderer> </render-kit> ``` How can I troubleshoot the registration of the custom renderer?
