ResultElement does not have a HTML but is an AbstractComponent rendering
its content using the renderComponent(). The name "ResultElement" is  
a little
missleading; in reality, ResultElement's renderComponent() method  
renders
a tree-like structure and needs to emit lots of DirectLinks with update-
Components:

In the meantime I've taken a look at DefaultLinkRenderer.java and see  
how
they output the onClick element. But this does not seem to anwser my
original question:

How can I programatically generate a DirectLink? Is the above way of
doing it (using getComponent("link"), referring to an existing  
DirectLink
component, that is) the "right" way? If so, how would I add a body to
the component?

I'd prefer to generate the link like this:

   DirectLink mylink = new DirectLink(...);
   // how to add the body of the link?

How can I do this?
