That looks like another framework, not Tapestry. With that approach, you add a lot of code and lose out on a lot of Tapestry features in terms of data type coercion and built-in smarts about caching.

> In tapestry 5, most things are done in codes and I like that approach. So naturally I want to pass parameters to components in codes.
> The parameters must be passed using attributes in html or in code like this:
> @ComponentClass
> public class Start {
> 	private String name = "john";
> 	@Component(parameters={"value=name"})
> 	private Echo echo;
> }
> I'd like to set parameters in code like following:
> @ComponentClass
> public class Start {
> 	private String name = "john";
> 	@Component
> 	private Echo echo;
> 	@SetupRender // or BeforeRender
> 	public void initComponents() {
> 		echo.setValue(name);
> 	}
> }
> It's more swing alike and has all the benefits of typed using like refactoring and static type check.
> Currently, Tapestry will complain that the required parameters not filled. I think move the required parameter checking AFTER the @SetupRender will work. But another issue is that it seems that you can't set parameter value using method like setValue.
> BTW, Wicket also uses this style of component parameter setting as I know.
