JSF Plugin

Hi Brown:

I have a case about the JSF. I my faces-config.xml, setting is as appendex A1. I get start with my first page, index.faces. But when I do some static navigation based on JSF, it fails. I trace on it, it show me the error as appendex A2. Detial code is :
ActionConfig config = ctx.getActionInvocation().getProxy().getConfig();

ctx.getActionInvocation() is got null. So I want to know what shall I set if I want to use the normal navigation above JSF.

Thanks
Watson
