Help with PrimeFaces

I am working slowly through the PrimeFaces showcase, I am using NetBeans 7.0, JDK1.6, PrimeFaces 2.2.1, GlassFish 3.1, JSF 2.0, Win XP Prof

Some of the examples work fine, others don't work and then I get errors that a component doesnt exist in the library or the component doesn't have a specific attribute. I have not done any configuration and the purchased very lacking PrimeFaces Manual seemed to suggest I didn't need to

I keep reading about snapshots and am wondering, should I be using a snapshot:

1) Do I need to use this snapshot to get everything to work, if so HOW do I use it?

2) Is there any more documentation / tuts / examples/ books ... of using PrimeFaces components with the above requirements that I have, that have been tested and work.

I have tried other forums but get no response, I would like to eventually develop some apps using PrimeFaces, but can't get the answ开发者_开发技巧ers or help I need.

On the Primefaces web page there is a "Showcase 2.2.1" and a "Labs Showcase 3.0". Maybe you tried some features of the Labs Showcase with your 2.2.1 installation?

If not, please give an example of a not working component.
