Craig, I was actually referring to the class names. I was confused by the use cases app which didn't list the faces ViewHandler, NavigationHandler, etc. Is there another working example which could show me how those work? I only saw the use case using the ShaleFilter, not the Shale JSF parts. As for why, I was wondering if Shale could work with FaceLets but after reading the API which suggests using the ShaleViewHandler, I'm doubting it since I don't think JSF can use multiple ViewHandlers in one webapp/JSF-config.

Can someone point that > out to me? > I'm not positive what "dollar signs" you are referring to ... but there are two delimiters for dynamic expressions that might be of interest: * "${xxx}" is typically an expression in the syntax/semantics supported by the JSP Standard Tag Library (JSTL), as well as that supported by JSP 2.0. These expressions are evaluated as the page is rendered, and are dynamically replaced by the result of the expression evaluation. Shale is totally agnostic to such expressions, and does not know whether or not they exist. * "#{xxx}" is a JSF 1.0/1.1 expresion. At rendering time, it has identical syntax and semantics to a corresponding "${xxx}" expression as described above. The difference is that a "#{xxx}" expression also has meaning on the subsequent postback caused by a form submit, when the JSP page that originally created this view no longer exists. Can you clarify which usage of expresion syntax you are referring to? NOTE: One of the primary objectives of the JSF 1.2 and JSP 2.1 specs was to resolve the semantic differences between the "${...}" and "#{...}" expression syntaxes -- but Shale itself doesn't care anything about this area. It's more an issue for the underlying JSP pages and JSF components that you are using.
