How can I add a component inside another component without template in T5?

[Carlos Gómez Montiel]

I have a component without template, how can I add another component
(render) inside it?

 

public class Component1 {

 

    void beginRender(MarkupWriter writer) {

        // How can I render for example a tapestry's textfield component
inside this component without have a template?

    }

 

}

 

Note: Component1 has no template (tml file)
