When the context param org.apache.myfaces.CONFIG_REFRESH_PERIOD is != 0 (which seems to be the default) the second page request causes a
javax.faces.FacesException: Undefined component type javax.faces.ViewRoot Exception.
In FacesConfigurator.class method void update() the method purgeConfiguration() is called. This method throws an NoSuchMethodException. In the catch block for this Exception there is a return; - so the configure(); below isn't called.
It looks like RenderKitFactory and / or CoreRenderKitFactory (trinidad) doesn't implement the purgeRenderKit method which is called by reflection from the purgeConfiguration() method - so the Exception rises up.
Setting the context param org.apache.myfaces.CONFIG_REFRESH_PERIOD to 0 works because the purgeConfiguration() is never called then.
