Re: how to contribute a 'component context' service

[Paul Stanton]

So I can either contribute a markup renderer that can access the 
renderSupport object OR inject a service that can in turn inject 
ComponentSource

but I can't create/contribute/inject my own object/service/etc that has 
access to all of RenderSupport, ComponentResources, ComponentSource and 
PageRenderQueue

or at least I can't piece together the snippets of information i can 
find to achieve this...

I need an object, populated with all of RenderSupport, 
ComponentResources, ComponentSource and PageRenderQueue 
accessible/injectable from every component (and page) whether partial or 
full rendering. Is this at all possible?

Thanks, Paul.

That doesn't seem to work Thiago, or maybe I'm missing something:

public class TapestryExtensionImpl implements TapestryExtension
{
    @Inject
    private Environment environment;

    @SuppressWarnings("unchecked")
    public <T> T getPage(Class<T> pageClass)
    {
        ComponentSource componentSource = 
environment.peekRequired(ComponentSource.class);
        return (T) componentSource.getPage(pageClass);
    }
}

ComponentSource is a service, not an environmental object, so you 
should inject it directly.

As Christophe said, you can learn a lot of Tapestry by looking at the 
TapestryModule source. That's how I got most of my Tapestry knowledge.
