The Clay component under Shale is another example of using an alternative 
method of adding components to the component tree.  There is an example in the 
uses cases for using xml and runtime composition.  An HTML layout use case is 
coming soon.

I originally had considered Velocity integration. The concern that I had was that if you could not create JSF components and associated listeners, converters and validators, you really only have a sophisticated outputText component and your really missing out on allot of what JSF has to offer over Velocity.
The approach that I was taking was to merge a document using Velocity and 
reparse it building a JSF component tree.  Craig was not comfortable with this 
dual processing and David ended up steering us to the Tapestry like views.

Not that it’s directly relevant to this thread…. but I thought I would share 
our experience.

Hi Gary I do not really see the problem here.
Your approach sounds interesting, but I see it also as a little bit to complicated... You might get better performance using velocity to render the pages instead of using it as a component renderer. But I think Craig was right with his opinion that dual processing might be a problematic route.


But I think there might be another approach if we follow the approach in this thread of per component rendering.

Velocity is only a templating language, and probably the best there is currently (combined with WebMacro).

The problem I see what you mean with providing the entire infrastructure is to get more stuff up and running, like the event system, you basically have to add some kind of rendering infrastructure into the velocity context which allows you to render the additional data and scripts into the template which are needed for the rest of the mechanisms (most of them are dynamically rendered javascripts)

I do not see a real problem there, it is however a lot of work, because what I could gather from my limited works on the components, most of this rendering stuff is helper methods which are somehow referenced from base components and those reference back into helper classes.

If you go that route for velocity, I would recommend to follow the tools approach of Turbine. Turbine basically uses IOCed classes which are sent into every rendered velocity template, they are used for many things (therefore called tools) And those tools for instance in Turbine are used for creation of static links out of dynamic and semi dynamic data, or delivering entire control sets (which is what I did once)

Rendering that stuff in velocity probably should follow a similar approach of providing tool objects for every rendered template, which can enable the actions and other stuff, basically a lot of infrastructure JSF provides...
