I'm using Glassfish V4 and Mojarra 2.2.x is already installed.
But, I use MyFaces 2.1.15 in my application.
java.lang.RuntimeException: The JSF implementation 2.1.15 does not support the RichFaces ExtendedPartialViewContext. Please upgrade to at least Mojarra 2.1.28 or 2.2.6
Mojarra is on the classpath by default.
Hope you can do something with it!
