Hi!

I have been wondering about some ways to write even less configuration with Tapestry-IoC and yet more convention over configuration.

At first we had:

public static void bind(ServiceBinder binder) {
        binder.bind(Service.class, ServiceImplementation.class);
}

Then, if ServiceImplementation is in the same package, we can write:

public static void bind(ServiceBinder binder) {
        binder.bind(Service.class);
}

I'm thinking of not even have that binder.bind() call, automatically binding services located in packages defined by some convention. How could I implement that? Can we add services to a Registry or use ServiceBinder just like we can use add objects to a service distributed configuration? I spent some time looking at the Tapestry sources, but I couldn't find an answer.

Another related funcionality I was thinking was to automatically provide some well-know service implementations when no one was explicitly providaded. Example: suppose we have the convention that every entity class must a corresponding controller class. Then I want to provide a default controller implementation for it if none is provided, because some components and pages expect one controller instance for each entity class. How could I do that?

My goal is to to have non-trivial zero configuration (or almost zero configuration) applications in Tapestry, provided that they follow the conventions.

Thanks in advance. :)
